Photoelectrochemical (PEC) water splitting supplies an environmentally friendly, sustainable approach to generating renewable hydrogen fuels. Oxides semiconductors, e.g. TiO2, BiVO4, and Fe2O3, have been widely developed as photoelectrodes demonstrate the utility in PEC systems. Even though significant effort has made increase efficiency, these materials are still far from practical applications. The main issue of metal oxides is wide bandgap energy that hinders effective photons harvesting...
