<P>PROBLEM TO BE SOLVED: To provide a photocatalyst coating liquid, capable of producing an inorganic material which has excellent photocatalyst function when used under an environment where it contacts with water. <P>SOLUTION: The photocatalyst coating liquid contains photocatalytic titanium oxide particles, alkali silicate, copper, and alkanol amine and/or quaternary ammonium. The content of the copper is 0.03<CuO/TiO<SB POS="POST">2</SB><0.3, relative to the photocatalytic titanium oxide particles, in terms of CuO-based mass ratio, and when silver is included as an optional component, its content is Ag<SB POS="POST">2</SB>O/TiO<SB POS="POST">2</SB><0.001 in terms of Ag<SB POS="POST">2</SB>O-based mass ratio. The inorganic material having photocatalystic function is obtained by applying the coating liquid to a substrate followed by baking. <P>COPYRIGHT: (C)2013,JPO&INPIT |
