PHOTOCATALYTIC BODY AND METHOD FOR MAKING SAME

摘要

The invention relates to a photocatalytic body having a good photocatalytic function characterized by using an amorphous titanium peroxid e sol, and a method for making the same. A photocatalyst such as titanium oxid e in the form of powder or a sol and an amorphous titanium peroxide sol are mixed in different mixing rations depending on the purpose in use and the resultan t mixture is coated onto a substrate such as an organic polymer resin, dried.cndot.solidifed and/or baked to support and fixed the photocatalyst on the substrate to make a photocatalytic body. Alternatively, a first layer consisting of an amorphous titanium peroxide sol on a substrate, and a second layer mad e of a photocatalyst is formed on the first layer to make a photocatalytic bod y. According to the invention, the photocatalyst can be supported and fixed on the substrate without lowering the photocatalytic function of the photocatalyst to obtain a photocatalytic body which is usable over a long time.
