Aldehyde replacement advances efficient hydrogen production in electrolyser

Abstract

The high energy consumption and production of undesired oxygen greatly restrict the wide adoption of water electrolysis for hydrogen production. In a paper recently published in Nature Catalysis, Wang and coworkers rationally introduce aldehydes for oxidation at anode to replace oxygen evolution reaction, which can produce hydrogen and value-added products at low potential, realizing efficient bipolar hydrogen production with high-purity. Moreover, these aldehydes are biomass-derived and contribute to sustainable hydrogen production.
