摘要
高效电催化氧还原反应催化剂的设计是推动金属空气电池和燃料电池应用的关键。双原子催化剂因具有协同作用的活性位点,显著提升了电催化氧还原活性、选择性和稳定性。目前关于双原子催化剂协同强化电催化氧还原反应的作用机制尚不明确,基于此,重点综述了双原子催化剂在电催化氧还原反应中的研究进展,总结了强化电催化氧还原反应性能的双原子催化剂调控机制,包括双功能协同机制、几何效应、电子效应等,对双原子催化剂在电催化氧还原反应中的机遇与挑战进行了展望,为设计高效双原子催化剂提供了借鉴思路。
The design of efficient electrocatalyst for the oxygen reduction reaction(ORR)is crucial for advancing the practical applications of metal-air batteries and fuel cells.Diatomic catalysts(DACs)have attracted considerable interest due to their synergistic active sites,which significantly enhance the electrocatalytic ORR performance in terms of activity,selectivity,and stability.However,the exact mechanism through which these DACs achieve such synergistic enhancement remains inadequately understood.The recent advances in DACs for ORR are reviewed,with a focus on the regulation strategies that enhance catalytic performance,including the bifunctional synergistic mechanism,geometric effects,and electronic effects.These insights provide valuable guidance for the atomic-level design of efficient DACs.Furthermore,future opportunities and challenges for DACs in ORR electrocatalysis are discussed.
