The role of water in reducing WO3 film by hydrogen: Controlling the concentration of oxygen vacancies and improving the photoelectrochemical performance.

Abstract

H2O, as a product of reduced reaction by H2, may affect the chemical equilibrium according to the changing of the pressure ratio of H2O/H2 in the system. Meanwhile, the performance may also be influenced by adsorption of H2O on the surface of the material. In this work, the effect of H2O is studied by reducing plate-like array WO3 films under different… (More)
