Abstract:

Water electrolysis is one of the most efficient and environmentally benign methods for the hydrogen production using renewable but intermittent power sources. Proton exchange membrane (PEM) water electrolyzers hold great significance for renewable energy storage and conversion. The acidic oxygen evolution reaction (OER) is one of the main roadblocks that hinder the practical application of PEM water electrolyzers. Highly active, cost-effective, and durable electrocatalysts are indispensable for lowering the high kinetic barrier of OER to achieve boosted reaction kinetics. To date, a wide spectrum of advanced electrocatalysts has been designed and synthesized for enhanced acidic OER performance, though Ir and Ru based nanostructures still represent the state-of-the-art catalysts. In this Progress Report, recent research progress on novel electrocatalysts with acidic OER performance is reviewed. First, the basic understanding of acidic OER, including the reaction mechanism, is discussed. On this basis, the design and synthesis progress of noble metal acidic OER electrocatalysts are reviewed for noble metal Ir, Ru single atoms, alloys, oxides, etc. Finally, the future development of acidic OER is prospected from the aspects of reaction mechanism research and more efficient electrocatalyst design.

Key words: Acidic oxygen evolution reaction, Iridium-based catalysts, Ruthenium-based catalysts
