摘　　要：催化剂的亲疏水性是影响氧还原反应(Oxyen Reduction Reation,ORR)性能的关键因素之一。本文综述了亲疏水调控策略在提高催化剂性能方面的应用,包括杂原子掺杂、结构设计、表面改性等方法。特别强调了超亲水和超疏水表面在促进氧气传输、增加活性位点和改善三相接触界面方面的作用。为设计高效、稳定的催化剂提供了理论基础和实践指导。The hydrophilicity of catalyst is one of the key factors affecting the performance of oxygen reduction reaction(ORR).This paper reviews the application of hydrophilic and hydrophobic regulation strategies in improving catalyst performance,including heteroatom doping,structure design,surface modification and so on.In particular,the role of superhydrophilic and superhydrophobic surfaces in promoting oxygen transport,increasing the active site and improving the three-phase contact interface is emphasized.It provides theoretical basis and practical guidance for designing efficient and stable catalysts.
