CA 2222869

The invention relates to a photocatalytic body having a good photocatalytic function characterized by using an amorphous titanium peroxide sol, and a method for making the same. A photocatalyst such as titanium oxide 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 resultant 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 made of a photocatalyst is formed on the first layer to make a photocatalytic body. 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.

L'invention se rapporte à un corps photocatalyseur présentant une excellente fonction photocatalytique par l'utilisation d'un sol de peroxyde de titane de type amorphe, ainsi qu'à son procédé de production. On prépare un photocatalyseur tel que l'oxyde de titane sous forme de poudre de sol et un sol de peroxyde de titane de type amorphe selon divers rapports d'un mélange conformément à certaines applications. Ce mélange est ensuite appliqué sur un substrat constitué d'une résine polymère organique et autre, puis est séché, solidifié et/ou fritté de façon à obtenir un corps dont le photocatalyseur est supporté et fixé sur le substrat. On obtient également un photocatalyseur pourvu d'une première couche de sol de peroxyde de titane de type amorphe et d'une seconde couche comprenant le photocatalyseur de la première couche. On obtient ainsi un corps pouvant supporter et fixer le photocatalyseur sur le substrat sans que la fonction photocatalytique soit réduite, et pouvant être utilisé sur une longue durée.
