PHOTOCATALYST USING OXIDE CONTAINING TYPICAL METALLIC ION IN d10 ELECTRONIC STATE

摘要

PROBLEM TO BE SOLVED: To provide a novel photocatalyst, particularly useful for the complete decomposition of water. SOLUTION: The photocatalyst, particularly the photocatalyst for the complete decomposition of water is composed of an RuO2 supported B2 Xn Om (where, B represents an alkaline earth metal atom or Zn, X represents a metallic ion in d<10> electronic state and particularly Ge, Sn or Sb, (n) has a relation of n=(m-1)/3 and (n) represents 1 or 2).
