Document Type and Number:
WIPO Patent Application WO/1997/036677
Kind Code:
A1
Abstract:
A photocatalyst body having an excellent photocatalytic function by using an amorphous type titanium peroxide sol, and a production method thereof. A photocatalyst such as titanium oxide in the powder of sol form and an amorphous type titanium peroxide sol are prepared in various mixing ratios in accordance with intended applications; the mixture is then applied to a substrate made of an organic polymer resin, etc., and is thereafter dried, solidified and/or sintered so that a photocatalyst body having the photocatalyst supported and fixed on the substrate is produced. Also, a photo catalyst having a first layer made of the amorphous type titanium peroxide sol disposed on the substrate and a second layer comprising the photocatalyst on the first layer is produced. A photocatalyst body is provided that can support and fix the photocatalyst on the substrate without lowering the photocatalytic function of the photocatalyst and can be used for a long time.
