摘要: Black TiO2 was usually obtained via hydrogenation at high pressure and temperature. Herein, we reported a facile of in the presence small amount Pt relatively low temperature atmospheric pressure. The hydrogen spillover from to accounts well for greatly enhanced capability. as-synthesized Pt/TiO2 exhibits remarkably improved photocatalytic activity water splitting.
