Photocatalyst-carrying structure and photocatalyst coating material

A specification photocatalyst support structure and photocatalyst coatee Tongue agent Technical field :

growth control of the present invention, antifouling, clean water, deodorization, sterilization, effluent treatment, a moisture solution, and an alga -- and -- each -- It is related with the structure which supported the photocatalyst used for a seed chemical reaction etc. Background art :

the energy of ultraviolet rays -- disassembly of water, deodorization, sterilization, purification of water, effluent treatment, etc. Photocatalyst which advances various kinds of chemical reactions it carries out -- oxidization Chita of an n type half-' conductor A -- Knowledge . Being. It is also the shape of powder about a photocatalyst. It spreads. Those who used it in the form where solution was made suspended are generally Touch. In the form supported on a certain carrier practical although it was said that intermediation activity was high It must be used in many cases. The energy of the ultraviolet rays which are light is exploited effectively. In a sake, Paper Si 1 with possible the shape of a carrier taking a large irradiation area of light To the shape of To contact with that it is more advantageous to carry out and a reaction thing [ a thing ] to make it start a chemical reaction with a photocatalyst moreover Size comes Touch area. The direction in which the surface is vesicular structure in order to carry out To is good Up. It is by carrying out and is .. It is proposed, for example, various carrier quality of the materials which support a photocatalyst are (A) nitroglycerine cells. Sirloin, Glass, polyvinyl chloride, and Plastic, Nay Ron, Metaku Lil resin, Poly Light transmittance state substances, such as propylene (Provisional-Publication-No. 6 2 -- 66 8 6 1) (B) Poly Prop The Wren textiles and Serra Mick (Provisional Publication No. 2 -- 6 8 1 9 0), (C) glass, and Serra Mick, nylon, and bitter taste There are Lil, polyester (Provisional Publication No. 5 -- 3 0 9 2 6 7), etc.

However, the thing which makes an organic matter a subject in the quality of the material of these, If a photocatalyst is supported An organic matter being disassembled by the catalytic action, or deteriorating has been reported. (Fumiaki Otani, polymer processing 4 2 volume, No. 5, P 1 8 (1 9 9 3), Seino Education, and "oxidization Chita A" Gihodo Shuppan Co., Ltd., P 1 6 5) in which a problem was in endurance.

Carrier materials are glass and Serra. Even if it is a case of inorganic substances, such as Mick, Photocatalyst If organic polymers resin is used for adhesives in order to support, a photocatalyst particle surface is resin. Catalyst activity not only falling, since it is covered but this resin is a part by photocatalyst operation. The problem arose also in To etc. which cause solution degradation and a photocatalyst * Detaches, and endurance.

Then, when carrier material is a heat-resistant inorganic substance, Spa where an organic matter does not remain at all Buddha The ring method (Provisional-Publication-No. 6 0 -- 0 4 4 0 5 3) Organic Chinese 1 Application of ♪ -- The calcinating method (JP,6-0,A - 1 1 8 2 3 6) Spraying of Chi Tha A Titania sol -- Methods, such as the calcinating method (Provisional Publication No. 5 -- 2 5 3 5 4 4), are adopted.

however, generation of the method of these, and the photocatalyst particles on a carrier, crystallization, and a carrier in order to give adhesiveness -- support of that calcination by high temperature is required, and a large area -- it can do -- To it is -- foolish Rika and manufacture Kos There was a problem said that ♪ is very high.

On the other hand, in order to support a photocatalyst on glass fiber paper, it is metal oxide sol as adhesives. The method of using (Provisional Publication No. 5 -- 3 0 9 2 6 7) is proposed. - since [ however, ] the adhesive strength of metal oxide sol, such as the Thilly power sol, is what is depended on fan' A deer . Wharska -- very much -- weak (Finance mix 1st volume p 2 1 6~)

2 2 3 1 9 8 0, adhesiveness, and endurance are insufficient -- again -- with baking in high temperature Processing by being required -- all the carriers which include thermal decomposition for Crawl general-purpose resin It is inapplicable.

Example smell which supported photocatalyst powder to metal oxide gels, such as the Thilly power and argillite The, It is Propionaldehyde by the effect as adsorbent of a carrier. Photocatalytic degradation of Degas with the report to which it was presupposed that a reaction is carried out as for Prompt . Advance (symposium" the latest deployment "of a photocatalytic reaction proceedings, 1 9 9 4, an optical functional-materials study group, 2 - 1 1, p .3 9).

However, like this It is high in the photocatalyst uniformly distributed in the metal oxide gel carried out. Report referred to as having acquired the support object which was [ having maintained catalyst activity ] excellent in adhesiveness and endurance as There is nothing and it is Oh.

How to fix a photocatalyst by a fluoro-resin is also proposed. (Provisional-Publication-No. 6 -)

3 1 5 6 1 4. however, a fluoro-resin is [ about / being expensive ] firm in power and photocatalyst particles covering many of catalyst particle surfaces by a fluoro-resin, in order to paste up -- Must it is an important point -- a result -- the time of catalyst activity and powder -- comparing -- falling -- stripes There was Problem of saying. a photocatalyst -- Hook matter Resin polyorgano mixing with difficulty resolvability binders, such as Shiroki Sun, -- basis although the body has support Learn more and tried Example (E P -- 0 6 3 3 0 6 4) -- adhesiveness and a long period of time -- -proof -- It is insufficient for solution of practical subjects, such as Kumi.

As mentioned above, it does not solve in order to support a photocatalyst on a carrier. Subject which The does not become It carries out, 1 ) -- that Adhesiveness of Photocatalyst and Carrier is Good, and 2 Photocatalyst Activity -- Carrier Do Not Fall by being Supported Upwards, 3) the supported photocatalyst -- Carrier and adhesive does not deteriorate but it maintains intensity over a long period of time -- maintaining endurance and catalyst activity Three points of That, are mentioned. furthermore -- the case where it is used in the environment of heat and high humidity -- for example, -- It is required that the adhesion after being immersed in boil underwater should be excellent.

Photocatalyst Co 1 tee for supporting a photocatalyst to a carrier The characteristic required of a Tongue agent It carries out and the minimum is also one-month Desirable. It spreads.
