Photocatalytic Material, Method for Decomposing Organic Matter, Interior Material, Air Cleaner, and Oxidizing Agent Production Apparatus

PROBLEM TO BE SOLVED: To provide a metal ion-doped titanium oxide type photocatalyst material which shows high oxidation decomposition activity by visible light radiation. ; SOLUTION: The photocatalyst material includes a metal ion-doped titanium oxide, which is made to have a potential of the valence band of 3 V (vs. SHE, pH=0) or higher and a band gap of the level of electrons excited from the valence band (including the conduction band lower end potential and lone pair potential) from valence band of 3 V or lower by doping titanium oxide with a metal ion, and a cupric salt and/or a ferric salt supported on the surface of the metal ion-doped titanium oxide. The metal ion-doped titanium oxide is enabled to exhibit high oxidation and decomposition activity under visible light radiation by utilizing that the cupric salt and/or the ferric salt can work as a multi-electron reduction catalyst. ; COPYRIGHT: (C)2010,JPO&INPIT
