Recent advances in synthesis of metal oxides as photoelectrochemical catalysts for photoelectrodes in water splitting process

Abstract

Amidst the global challenges of energy supply and the severe impacts of climate change, hydro energy is considered one of the most crucial options to replace fossil fuels and contribute to the goals of clean and sustainable energy development. The water-splitting reaction plays a vital role in hydro production by separating and collecting hydrogen gas from water. This necessitates the presence of highly efficient catalysts that can accelerate the reaction rate and ensure sustainability during operation. The key focus of catalyst research and development lies in optimizing performance and reducing the cost of hydro production. In this report, we present some advancements in the synthesis of photoelectrochemical catalyst materials for oxide-based water-splitting reactions.
