Engineering Lower Coordination Atoms onto NiO/Co₃O₄ Heterointerfaces for Boosting Oxygen Evolution Reactions

Low-coordination atoms (LCAs) have been proven to play a critical role in boosting electrocatalysis. However, for enhancing catalytic activity, suitably engineering the LCAs in catalysts through rational design remains a challenge. Herein, we demonstrated self-supporting NiO/Co3O4 hybrids for advanced oxygen evolution reaction (OER) performance. Contributed to an abundance of heterointerfaces and increased oxygen vacancies at the interfaces, the...
