Dissolution and reconstruction of organic ligands in electrocatalysts for efficient OER

电催化剂中有机配体的溶解与重构引发的高效OER

Electrocatalytic water splitting is a highly promising method for green hydrogen production,which is highly important for sustainable and low-carbon societal development.Despite tremendous scientific and technological efforts dedicated to thisfield,its practical application faces challenges owing to heavy energy consumption,mostly from the elevated potentials needed for the oxygen evolution reaction(OER)at the anode[1].Strategies such as developing efficient OER electrocatalysts and using sacrificial agents or electrosynthesis-assisted water splitting have emerged,collectively known as‘‘electrocatalytic hydrogen production trilogy”[2,3].While the latter two strategies show potential,especially the last one,they are still in the early development stages.Currently,there is a pressing need for efficient OER electrocatalysts to promote the commercialization of electrocatalytic water splitting.
