Regulating the coordination environment of a metal–organic framework for an efficient electrocatalytic oxygen evolution reaction

Abstract

Oxygen evolution reaction (OER) plays a vital role in fuel cells, water splitting and metal-air batteries. Efficient electrocatalysts could overcome the higher overpotential of OER, improve electron transfer efficiency, and...

Machine learning-aided unraveling of the importance of structural features for the electrocatalytic oxygen evolution reaction on multimetal oxides based on their A-site metal configurations

“…Various electronic 7 and structural factors [8][9][10][11] have been proposed as descriptors of OER activity. These factors include the number of d electrons in the e g orbital of transition metals in perovskite-type multimetal oxides, 12 and the charge-transfer energy, 13 which represents the energy level gap between the occupied p orbitals of oxygen and the unoccupied d orbital of the transition metal.…”
