HYDROPHILIC MIRROR COATED TIO2 MEMBRANE ON CHROME PLATE

摘要

A photo-catalytic body is provided to improve the photo-catalytic characteristic, by forming the photo-catalytic body of an amorphous-phase titanium dioxide thin layer and an anatase-phase titanium dioxide thin layer. A first titanium dioxide thin layer of amorphous phase is coated on a chrome-plating layer(20) formed on a substrate(10). A second titanium dioxide thin layer(32) of anatase phase is formed on the first titanium dioxide layer. A silicon dioxide thin layer(40) is formed on the second titanium dioxide thin layer. The substrate is formed of one of glass, metal, and ceramic.
