NOVEL Z-SCHEME TYPE VISIBLE LIGHT ACTIVE PHOTOCATALYST SYSTEM FOR PERFECTLY DECOMPOSING WATER AND WATER PERFECTLY DECOMPOSING METHOD USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a Z-scheme type visible light active photocatalyst system using FeSP3+/SP/FeSP2+/SPredox system. PSOLUTION: The Z-scheme type visible light active photocatalyst system comprises a combination photocatalyst system composed of at least one oxygen forming photocatalyst selected from a WOSB3/SBsystem, a BiVOSB4/SBsystem and a BiSB2/SBMoOSB6/SBsystem and a hydrogen forming photocatalyst of Pt/SrTiOSB3/SB:Rh. An Fe compound for forming the FeSP3+/SP/FeSP2+/SPredox system constituting the Z-scheme type visible light active photocatalyst system is allowed to be present in the combination photocatalyst system.
