Photocatalyst body and method of production thereof

It relates to a photocatalyst having an excellent photocatalytic function, characterized by using an amorphous sol peroxide, and a method for preparing the same. A photocatalyst such as powdery or sol titanium oxide and amorphous titanium oxide sol are prepared in various mixing ratios depending on the use, and the product is coated on a substrate such as an organic polymer resin, dried, solidified and/or sintered. , to prepare a photocatalyst in which a photocatalyst is supported and fixed on a substrate. Further, a photocatalyst is prepared in which a first layer made of an amorphous titanium peroxide sol is placed on a substrate, and a second layer made of a photocatalyst is placed on the first layer. According to the present invention, the photocatalyst can be supported and fixed on the substrate without degrading the photocatalytic function of the photocatalyst, and a photocatalyst that can be used over a long period of time is obtained.
