The integration of tri-component semiconductors are a promising approach to utilize the solar light without the compromise of the redox ability of photogenerated charge carriers for H2 generation. In this study, a less finicky and effective method is developed to synthesize Fe2O3/TiO2/AgVO3 heterostructures. The as synthesized samples are characterized by XRD, SEM, TEM, HRTEM, XPS, EDAX, UVDRS, PL, RAMAN and FTIR techniques. The photocatalytic activity of Fe2O3/TiO2/AgVO3 heterostructures are evaluated by hydrogen production under solar irradiation. The possible mechanism for the enhanced photocatalytic properties of Fe2O3/TiO2/AgVO3 heterostructure is also discussed. |
