A semiconductor is irradiated with the light of a wavelength which has the energy more than the band gap. If it carries out, an oxidation-reduction reaction will arise. such a semiconductor -- a photocatalyst semiconductor -- it is it is -- it is only called a photocatalyst.

A photocatalyst, the case where it is powdered, make solution suspended and it is used, and base of some kind It may be used in the form supported upwards. it sees from the standpoint of photocatalyst activity Practical, although former one is generally more active from the size of the surface area are . considering a standpoint, it says from the ease of handling -- the former -- latter one -- Adoption -- not carrying out -- profit nothing and a case -- many t,

for making a photocatalyst support on a base -- a base top -- photocatalyst particles -- high temperature -- sintering -- Holding is carried out -- the method is adopted. Po of a certain kind of fluorine system The method of supporting a photocatalyst to a base, using Limmer as a binder is also proposed. It is. for example, Provisional Publication No. 4 -- 1 -- 2 8 4 8 5 No. 1 gazette -- photocatalyst particles and fluoride a system -- a mixture with polymer 1 -- lamination and the method of press-fitting -- Provisional Publication No. 4 -- 3 3 4 5 5 The method of carrying out thermal melting arrival of the photocatalyst particles to No. 2 gazette at fluorine system polymer 1 is indicated. ing. Provisional Publication No. 7 -- 1 7 1 4 0 In No. 8 gazette, The difficulty resolvability binder which consists of organic systems, such as inorganic systems, such as water glass, and silicon system polymer, is passed, and it is Light touch. It is the first about the binder of difficulty resolvability on the method of pasting up intermediation particles on a base, and a base. It provides as a layer, the first layer top -- the binder of difficulty resolvability, and photocatalyst particles -- from The manufacturing process of the photocatalyst object which provides the second layer of To is indicated. Provisional Publication No. 5 - 3 0 9 2 6 It is metal oxide Sol as support fixed material of No. 7 gazette photocatalyst powder. The method of using the metal oxide which carries out Generation is indicated, Organic metal compounds, such as Alkoxide of metal in which the sol of a metal oxide is adopted by a sol gel process, Assecil Assetne ♪, and carboxylate, and a chloride called titanium tetrachloride It is obtained by hydrolyzing an alcohol solution under acid or the Al power Li catalyst existence. There is a statement of a purport. The indication of an invention

these days, a photocatalyst is used -- the trial which decomposes, purifies or sterilizes the toxic substance which arises in an everyday living environment, a bad smell ingredient, oil, etc. occurs -- application of a photocatalyst The range is expanded quickly. it follows on this -- it being firm and going over photocatalyst particles on all bases, at a long period of time, without hurting the photocatalyst function The method of making it support is searched for. titanium oxide which was excellent in the photocatalyst function especially Binder 1 function to a base is [ case where sol is used as a photocatalyst ] weak. , -- especially the adhesive improvement was called for.

however, there are few the method of the above-mentioned conventional technology not being enough as adhesive strength and things which can be supported over a long period of time -- raising adhesive strength -- long -- If it tries to make what can be supported during the period, it will be said that a photocatalyst function falls conversely. There was a problem. rutile type oxidization said to compare with a Anatase type and for the photocatalyst function to be weak when using the base consisting of organic polymers resin even if it is titanium, a photocatalytic reaction advances -- the photochemistry of organic polymers resin itself -- anti- -- A deteriorated part understands it as Response by prolonged use conjointly.

moreover -- the case where organic polymers system resin is used as a base -- silica sol etc. beforehand -- Co 1 tee although it considered carrying out Tongue -- silica sol -- Condensation a crack and a hole occur in process of a collection and dryness -- performance top problem as a binder It was.

the above-mentioned subject should be solved -- photocatalyst particles -- all the base top -- the photocatalyst machine Without it hurts ability It is firm and there is direction made to support over a long period of time. Result for which it searched about the method, amorphous type titanium peroxide sol -- binder As -- if it is used -- being also unexpected and photocatalyst particles -- all the base top -- the photocatalyst Without hurting a function, it is firm and makes it support over a long period of time. it finds out that things are made -- the present invention was completed.

Namely, manufacturing process of the photocatalyst object which carries out support fixation of the present invention and the photocatalyst at a base It is, A photocatalyst and amorphous type titanium peroxide sol, such as titanium oxide Manufacturing process of the photocatalyst object to be used, On a base, it is amorphous type titanium peroxide sol. The first layer that does not have the Light touch function used and prepared is provided, On the first layer, it is Light touch. The second layer prepared using intermediation and amorphous type titanium peroxide sol is provided. It is related with the photocatalyst object manufactured by the manufacturing process of a photocatalyst object, and the method of these, and the photocatalyst constituent used for the manufacture.

the amorphous type titanium peroxide sol used in the present invention -- for example, -- It can manufacture as follows. Titanium tetrachloride T i C 1₄of -- it needs titanium salt water solution -- water oxidization like an ammonia solution thru/or water oxidization Na ♪ Lyme Al power Li is added. Titanium hydroxide T i (O H) 4 [ light blueness white / arising / and formless ] is alt. titanic acid H.₄T i 0₄it is called -- this titanium hydroxide -- washing . separation if it processes with the back and hydrogen peroxide solution -- peroxidation Chita of the amorphous form of the present invention A liquid is obtained. This amorphous type titanium peroxide sol is p H 6 .0*. 7.0, diameter of a particle It is 8* 20 nm. the appearance -- yellow -- it is a transparent fluid, and it is stable even if saved at normal temperature for a long period of time. sol concentration -- usually -- 1.4 although adjusted to 0* 1. 60 %, the concentration can be adjusted if needed -- when using it by low concentration, it is diluted and used with distilled water etc.

This amorphous type titanium peroxide sol, amorphous at normal temperature to Anatase type titanium oxide, it does not yet crystallize in the state -- adhesion nature -- A Re and membrane formation nature are high -- uniform -- Flush creating a Fancy thin film -- ' -- it can do -- and the dry tunic has the character in which it does not melt into water.

the sol of amorphous type titanium peroxide -- 1 It heats or more by 00. it becomes Anatase type titanium oxide sol -- amorphous type peroxidation Titanium sol -- a base -- Co 1 tee what carried out dry-after Tongue fixation -- 250 or more heating It becomes Anatase type titanium oxide.

It can be used in the present invention. As a catalyst, it is T i 0.₂Z nO, S r T i 0₃C d S, C d 0, C a P, I n P, I n₂O₃C a A s, B a T i O₃K₂N b 0₃F e₂O₃T a₂0₅W0₃S a 0₂B i₂0₃N i O. C u₂0, S i C, S i 0₂Mo S₂Mo S₃I n P b, R uO2, C e O₂although Such can be mentioned, titanium oxide is preferred also in these -- titanium oxide -- the shape of a particle, a powdered form, or a sol-like form -- use.

Sol-like titanium oxide, Namely, titanium oxide sol, It is above, Family type titanium peroxide sol It heats at the temperature more than 1 00"C. Although it can manufacture, Quality of titanium oxide sol is some by heating temperature and cooking time. It changes, For example 1 00 Anatase type oxidization generated by processing for 6 hours Titanium sol is p H 7. 5*9. 5 and a diameter of a particle. It is 8*20 nm. Besides [ the ]. A view is a fluid of yellow suspension. although it is stable even if saved at this titanium oxide sol and normal temperature for a long period of time -- acid and gold if it mixes with Aqueous solution etc., precipitation may arise -- again -- Na ion -- Existence If In is carried out, photocatalyst activity and acid resistance may be spoiled. Sol concentration is usually 2.7. 0*2.9 Although adjusted to 0 %, necessity is accepted, and it is the concentration. It can also be used, being able to adjust.

It is marketing although it is desirable to use the above-mentioned titanium oxide sol as a photocatalyst. "S T -- 0 1 J (made by Ishihara Sangyo Kaisha, Ltd.) and "S T - 3 1" (made by an Ishihara Sangyo stock company) can be used.

it sets to the present invention -- as a base -- Cerami the organic quality of the materials, such as quality of non-equipment, such as A and glass, a plastic, rubber, a tree, and paper, and aluminum -- Steel The thing of which quality of a metallic material can be used. It is a strike also especially in these. Ronitril resin, vinyl chloride resin, and poly power 1 Bonet resin and methyl Methacrylate resin (bitter taste Lil resin), polyester resin, polyurethane resin, etc. The effect which was excellent in application to an organic polymers resin material is demonstrated. the size it is not restricted to a form -- the shape of a honeycomb, the shape of a fiber, a Overpass sheet shaped, and bead What A state, the letter of firing, and they accumulated may be used. Ultraviolet rays are passed. On the article which could apply the photocatalyst object to the inside when it was a base, and was painted again It can apply.

it sets to the present invention -- the binder which is not disassembled with a photocatalyst, for example, the above Provisional Publication No. 7 -- 17 1 4 0 as [ describe / in No. 8 gazette ] -- water glass and Collot An inorganic system and fluorine system polymer, such as Pedals silica and cement, and Silicon-based port organic systems, such as Limmer, -- from -- the binder which is hard to be disassembled with the becoming photocatalyst -- meaning It carries out.

Next,' of some [ manufacture / the constituent for manufacturing the photocatalyst object of the present invention ] There is a method. First, titanium oxide powder is uniformly suspended to amorphous type titanium peroxide sol. The method of using what was carried out can be mentioned. In order to make it become muddy uniformly, it is advantageous to use an after [ mechanical Agitation ] ultrasonic wave.

next, the above-mentioned titanium oxide sol and Amor -- face -- type titanium peroxide sol -- Mixed it unites -- mixed sol is prepared. Both mixed percentage and the photocatalyst object of the present invention apply. Although determined by the operating condition of the product part carried out or apparatus, it is the mixed A that time. The adhesion to the base of the photocatalyst object prepared using Le, membrane formation nature, corrosion resistance, and makeup A sex etc. are taken into consideration. And it can approximately divide into the following three classification.

(1) people contact -- or the possibility is high -- visual -- makeup nature -- necessity it carries out -- for example, an interior tile, sanitary chinaware, and various Nun Inside of A products, tableware, and construction Exterior cases, automotive interior material, etc.

(2) although people do not contact, makeup nature is needed visually -- for example, a light, an underground passage, a road, a tunnel, engineering-works materials, an electrical-appliances face panel, etc.

(3) usually, contact and carrying out vision do not have people -- part of an organic matter based on a photocatalyst function the character which a solution function and the semiconductor metal itself have is used -- a septic tank and various Waste water treatment equipment, Water heater, a bath heater, air-conditioning equipment, and Range 1 the inside of Do -- constructing in apparatus in addition to this Crowded member etc.

And in the above-mentioned classification (1), they are titanium oxide sol and amorphous type peroxidation Chi. As opposed to a total amount with tongue sol, titanium oxide sol -- 3 It is mixture at 0% of the weight or less of a rate. That the photocatalyst object which formed membranes using the mixed sol carried out is preferred, and product using this Is it appears in the sterilization in everyday life, or pollution control and remains bad smell decomposition enough, and is in them, and the film surface is hard -- there is neither wear by cleaning etc. nor adhesion of miscellaneous No -- finger by contact It turned out that a crest etc. are not attached easily.

it belongs to the above-mentioned classification (3) -- a septic tank Remains of the last effluent treatment water In order to demote an organic matter (BO D) value, high photocatalyst activity, Light touch used it is the most important performance demanded as a medium -- this -- titanium oxide sol as opposed to a total amount with amorphous type titanium peroxide sol -- titanium oxide sol -- 7 The photocatalyst object which formed membranes using the mixed sol mixed at 0% of the weight or more of a rate is the optimal. A certain thing was understood. although makeup nature is inferior in this photocatalyst object -- thing of this classification people are usually contact and a thing which does not carry out vision -- when some residues adhere again, it is A problem, and periodical removal and cleaning showed that it obtained and could solve. furthermore -- the above-mentioned classification (2) -- titanium oxide sol and amorphous type peroxidation Chita as opposed to a total amount with Sol -- titanium oxide sol -- 2 0*8 It is mixture at 0% of the weight of a rate. It turned out that the photocatalyst object which formed membranes using the mixed sol carried out is suitable. it sets to the adhesion of this photocatalyst object, hardness, and miscellaneous No, photocatalyst activity, etc. -- front 2 persons' inside The character of a between is shown.

They are titanium oxide sol, amorphous type titanium peroxide sol, mixed sol, etc. to a base. It is a day in order to apply, or spray and act as Co 1 Tyng. Publicly known methods, such as Tsubingu, a spray with Blow, and an application, can be used. Coatee Tongue If it faces, it is good to repeat an application two or more times in many cases.

making it above -- an application -- or -- spraying -- coatee although it can be made to be able to dry, it can be made to be able to solidify after carrying out Tongue and the photocatalyst object of the present invention can be acquired -- 2 0 0*4 0 Solidification support can be sintered and carried out before and behind 0 °C. Oxidization Chita Since the photocatalyst function of A falls by Na ♪ Liuion, let it be a base. When organic polymers resin which is easy to receive decomposition by Photocatalyst is used, coating is preceded -- making the source of Na ♪ Lyme exist by Ning(ing) the resin surface chestnut 1 by the substance containing Na ♪ Lyme ion, such as sodium hydroxide solution Setting is advantageous.

It is 2 when using amorphous type titanium peroxide sol as the first layer. 5 When it heats to 0 or more The, it becomes a crystal of Anatase type titanium oxide, and is a photocatalyst. Since a function arises, it is low temperature, for example, 8, from it. Dry solidification is carried out or less by zero. It is Sodiumy in this case to titanium peroxide sol since it is the same as that of the above. ON is added. Things are also made.

Before fabrication, they are a photocatalyst, spontaneity type ultraviolet irradiance material, or phosphorescent model ultraviolet irradiance. The particles which mixed the particles which consist of a material of material, or these radiation material are mixed. Lycium chinense grows.

Spontaneity type ultraviolet irradiance material (spontaneity type luminescence ceramics) Internal energy Radiation collapse of radium and promethium is used by Material which consumes and emits light itself. It has an ultraviolet range in Am and luminescence. Such [ under the present circumstances ] an ingredient The crushed grain child who ground what hardened the refining powder of the included rock again is used. Phosphorescent model ultraviolet irradiance material (phosphorescent model luminescence ceramics) External energy It has an ultraviolet range in luminescence by Material which emits light while emitting taking in and its part. ing. "Luminova" (brand name , Inc. Nemoto) "Kiplass"

(Brand name Nexus, Inc. ♪ and eye) It is marketed. These and strontium aluminum Nate containing the ingredient of highly pure Alumina of a degree, carbonic acid strontium, Yu mouth Pium, dysprosium, etc. (S r A l)₂0₄Main ingredients It carries out. absorption Speak the maximum point of Toru -- 3 6 it is in 0 n m -- particle diameter -- 2 0 m* 5 It is 0 beta *eta. However, it is the Up about the thing in the state where it crushed before pulverization. It can also obtain as Shredding particles.

In these commercial items, if humidity is absorbed, performance will fall greatly and will carry out. In the case of a Watch thing it is beforehand like Glass poly car Bonate -- transparent are . it can also enclose and use into organic polymers resin -- it carries out -- again -- the inside of a base -- Mixed It can also be used, being able to stick on carrying out ON or the base surface.

Such spontaneity type luminescence Cerami Cuckoo luminous type luminescence Cerami Particles which particle Yes 'of A mixed the particulates of these ceramics, and were fabricated (the following and mixing particles it calls) If it mixes to a photocatalyst and a photocatalyst object is prepared, Outside of the purple to a photocatalyst object Even if irradiation of a line is interrupted, he is spontaneity type luminescence Cerami. Outside of the purple emitted from A particles Line, or phosphorescent model luminescence Cerami Enel which the particles of A accumulated by then the ultraviolet rays which consume and emit Gee -- the photocatalyst semiconductor of a photocatalyst object -- excitation -- Re and a photocatalyst function are maintained. Spontaneity type luminescence Cerami A and phosphorescent model luminescence Cerami Since the particles of A, and usual green and blue or orange visible light are also emitted, it can use for guidance by Decoration ** using this.

A photocatalyst semiconductor and its composition are adjusted. (addition of an inorganic pigment or metal) It carried out. Required for exertion of a catalyst function by adjusting heat treatment in Ri and a manufacture process It is changeable, wavelength of ultraviolet rays (absorption belt), i.e., the excitation wavelength, to carry out. For example, T i 0₂It is alike and is C r 0.₃If small-quantity addition is carried out, an absorption belt will be displaced to the long wavelength side._cthis -- the photocatalyst object side -- spontaneity type ultraviolet irradiance material or phosphorescent model ultraviolet irradiance material it can unite with the emission-spectrum characteristic -- wavelength of the ultraviolet rays supplied The set photocatalyst semiconductor can be chosen.

On the other hand, being contrary to this, spontaneity type ultraviolet irradiance material, or phosphorescent model ultraviolet irradiance material Luminescence Speak The Toru characteristic can also be united with the excitation wavelength of a photocatalyst semiconductor. For example, the excitation wavelength of titanium oxide is 1. 8 0 n m*4 0 It is it although it is 0 n m. There is nothing that is marketed now by the phosphorescent model ultraviolet irradiance material which balances.

phosphorescent Cerami who does an afterglow for a long time which is marketed as A -- Nemoto there is "N noctilucence" of incorporated company -- afterglow time -- 1 0 0 There is also a 'thing exceeding 0 minute._cThis adds alumina for carbonic acid Stronchiu carbonic acid calcium to the main materials. Yu mouth Bium and dysprosium are added as a Activation agent, They are a lantern, cerium, praseodymium, samarium, and power U U in it, terbium and Hol boric acid is added as Vlux and it is [ Mom, erbium, thulium, ytterbium, lutetium, manganese, tin, which element of bismuth, and ] 1. 3 It heat-treated by 0 o"c, and the phosphorescent ceramics of the afterglow are produced for a long time. this -- In a mixed process, short wavelength is also a blue photogen with a peak of 440 nm most. this is made into the luminescence wavelength below 400 nm which is an excitation wavelength of titanium oxide To The absorption wavelength with a peak of 360 nm which the above-mentioned "N noctilucence" has, and 44 It is Addition about the addition metallic elements for bringing the luminescence wavelength with a peak of 0 nm close. Power to acquire, or strontium, potassium, Borax, etc. and a mineral have -- from the first blue luminescence before and behind 450 nm which is the phosphorescence wavelength characteristic -- 44 Below 0 n m a luminescence wavelength does not arise -- then although a phosphorescence color does not emit light, it is short wavelength much more than strontium etc. -- luminescence wavelength below 400 nm which does not carry out coloring the mineral element which it has is refined -- This which carries out preparation processing and develops phosphorescent model ultraviolet irradiance material It can do.

When making only the surface of a photocatalyst semiconductor and unit particles support beforehand He is spontaneity type luminescence Cerami to unit particles. Cuck um luminous Cerami The particles or Mixed of A The surface of the whole after mixing ON particles and making it a cast may be made to support. former one -- spontaneity type luminescence Ceramic, phosphorescent luminescence Cerami the particles of A -- or -- a photocatalyst semiconductor does not adhere to the surface of mixing particles -- it emanates from these particles -- purple The quantity of outside line increases. the case of a phosphorescent model luminescence ceramic particle -- the exterior , -- ultraviolet rays are efficiently absorbable.

Photocatalyst function auxiliary addition metal (P t, A g, Rh, Ru O, Nb, C u, S n, N i O, etc.) may be added to a photocatalyst object in the manufacture process. . embodiment by which these are well known as what carries out the promotion complement of the photocatalytic reaction

Although a reference example and an example are hung up over below and this invention is explained to it still more concretely - The scope of this invention is not limited to these illustration. Reference example 1 (manufacture of amorphous type titanium peroxide sol)
