Abstract

Photocatalytic reaction is a challenging topic because it is an important solution to energy and environmental issues. Recently, many oxide composited powders for water splitting have been developed. For example, Pt/ZnO, TiO₂ photocatalystwith a 3.2 eV band gap showed high activity for water splitting into H₂ and O₂ withan apparent quantum yield of 67% at near UV ranges. In this composite, two oxide couples as an electron relay system employing to increase the efficiency of hydrogen production. Moreover, highly efficient for solar hydrogen production in the presence of electron donors were developed by adding platinum.
