Photocatalytic decomposition of pure water over NiO supported on KTa(M)O-3 (M=Ti4+,Hf4+,Zr4+) perovskite oxide

摘要

Photocatalytic decomposition of pure water on NiO supporting KTaO3 partially substituted with acceptor was investigated. Formation rate of H-2 and O-2 increased by partially substituting Ta with group 4 element. The increased photocatalytic decomposition activity by additives might be caused by a charge carrier annihilation. [References: 6]
