Water Splitting Reaction by Coupled Semiconductor Photocatalysts

Abstract:

Photocatalyst materials is a challenging topic because it can be used in an important solution to energy and environmental issues. Recently, Z schemes based catalysts have been developed for increaseing the efficiency of water splitting process. In this paper, Pt doped Zno@ TiO₂ photocatalyst with a 3.2 eV band gap showed high activity for water splitting into H₂ and O₂ with an apparent quantum yield of 6.8 % 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.
