Photoelectrochemical (PEC) water splitting to produce hydrogen fuel is an attractive strategy to achieve a sustainable energy supply. To achieve stable hydrogen production, light harvesting, charge separation/transport, charge transfer, and the stability or durability of PEC cells are strongly required. In recent years, cost-effective, stable, and earth abundant n-type metal oxides have been extensively studied for the efficient PEC water oxidation. However, the slow charge migration, electronic-state-mediated rapid trapping, and poor surface catalytic kinetics of metal oxides remain a significant obstacle for its use as a water oxidation catalyst. As a part of our effort to achieve simultaneously high light absorption, charge separation, and charge transfer efficiencies, divergent metal oxide based photoanodes have been rationally designed to have efficient heterojunction structures. Our recent findings on strategies to improve the metal oxide nanostructure based photoelectrochemical water oxidation will be introduced in this talk.
