Abstract

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