  • Publication number: 20010019776
    Abstract: A hydrophilic treatment by the use of a surface active agent and the like is not required for a base even the surface of which is water-repellent or thermoplastic when a viscous amorphous type titanium peroxide is used for fixing a base as a binder. In addition, a thin layer of a photocatalyst semiconductor, a dielectrical ceramics or an electrical ceramics can be easily formed by adhering particles of a photocatalyst semiconductor, a dielectrical ceramics or an electrical ceramics to the layer of a viscous amorphous type titanium peroxide, which is a layer as a binder, in a homogeneously floating state gas. Furthermore, a layer of a titanium oxide having a photocatalyst function can be formed when a base is fixed with a viscous amorphous type titanium peroxide.

  • Patent number: 6107241
    Abstract: 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-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.
