摘要
Abstract
The unavailability of high-performance and cost-effective electrocatalysts has impeded the large-scale deployment of alkaline water electrolyzers.Professor Zidong Wei's group has focused on resolving critical challenges in industrial alkaline electrolysis,particularly elucidating hydrogen and oxygen evolution reaction(HER/OER)mechanisms while addressing the persistent activity-stability trade-off.This review summarizes their decade-long progress in developing advanced elec-trodes,analyzing the origins of sluggish alkaline HER kinetics and OER stability limitations.Professor Wei proposes a unifying"12345 Principle"as an optimization framework.For HER electrocatalysts,they have identified that metal/metal oxide interfaces create synergistic"chimney effect"and"local electric field enhancement effect",enhancing selective in-termediate adsorption,interfacial water enrichment/reorientation,and mass transport under industrial high-polarization conditions.Regarding OER,innovative strategies,including dual-ligand synergistic modulation,lattice oxygen suppres-sion,and self-repairing surface construction,are demonstrated to balance oxygen species adsorption,optimize spin states,and dynamically reinforce metal-oxygen bonds for concurrent activity-stability enhancement.The review concludes by addressing remaining challenges in long-term industrial durability and suggesting future research priorities.关键词
