Outline of Final Research Achievements

We investigated the effect of co-catalyst loading on photocatalytic activity of Ni-doped Mn-Cd based sulfide photocatalysts and development of water splitting reaction system consisting of our sulfide based photocatalysts for H2 evolution and O2 evolution photocatalysts. We found that Pt loaded Ni-Mn-Cd sulfides showed stable H2 evolution with 25% of quantum yield. Moreover, we also found that the photocatalyst system composed of Pt loaded Ni-Mn-Cd based sulfide photocatalyst and co-catalyst loaded BiVO4 and electron mediator showed water splitting under visible light irradiation.
