Recent advances of polyoxometalates in water electrolysis

Le résumé fourni par la source

Electrolytic water splitting for hydrogen production is a highly promising green hydrogen preparation technology, featuring renewable raw materials, high product purity, zero carbon emissions, and compatibility with fluctuating renewable energy sources such as wind and solar power, thus facilitating the achievement of the "dual carbon" goals. Polyoxometalates (POMs) offer an efficient solution for this technology, with adjustable structures, reversible multi-electron transfer capabilities, and excellent catalytic activity. Their electronic structures can be optimized through strategies such as metal substitution and interface anchoring to lower the reaction energy barrier. Additionally, POMs can prevent catalyst dissolution and deactivation, enhance stability under acidic or alkaline conditions, and improve electrolytic efficiency through a synergistic proton-electron transfer mechanism, significantly reducing energy consumption. This article mainly introduces the applications of POMs in oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and bifunctional catalysts, and reveals the structure-activity relationships, providing an important direction for the development of low-cost and highly stable electrolytic water splitting catalysts for hydrogen production, and promoting the large-scale production of green hydrogen.
