摘　　要：Electrocatalytic water splitting,which is recognized as an ideal technology to tackle escalating energy demands and related environmental problems,has attracted growing interest.The sluggish dynamics of the oxygen evolution reaction(OER)has posed an intractable problem in this regard,hindering the practical commercial application of hydrogen production via water splitting.Therefore,the development of active and stable electrocatalysts is a prerequisite for accelerating OER kinetics,which greatly relies on the mechanistic understanding of the structural-property relationship.Owing to the harsh anodic oxidation conditions,most of the catalysts undergo surface reconstruction during the OER process,which means the authentic active sites are the in-situ reconstructed species rather than the freshly prepared one.In this regard,fully comprehending the surface reconstruction process will help us to determine the active sites on the catalyst surface and gain insights into the design principles for more efficient OER catalysts.In this review,we will first give a summary of surface reconstruction of OER electrocatalysts.Then we will focus on the factors that affect surface reconstruction,in-situ/operando characterization technologies,and the strategies to govern surface reconstruction.In addition,we outline existing challenges and the outlook for the development of OER catalysts by tuning surface reconstruction.
