摘　　要：析氧反应作为水分解反应的一个半反应,由于其在反应过程中需转移更多电子,因此研究性能优异的析氧催化剂意义重大。铁因其储量丰富,毒性小,优异的氧化还原性质而逐渐受到关注,从而铁基催化剂用于电催化析氧反应的研究逐步深入。电沉积法,因其制备简单、重现性好等优势,而作为制备铁基催化剂一大基本方法,因此分析总结电沉积方法对制备析氧催化剂起到一定的参考作用。电沉积法主要分为两类:阳极电沉积法和阴极电沉积法。通过展现这两种方法制得的铁基催化剂的析氧性能的差异,为新型提升性能的催化剂的合理开发提供进一步的依据。As half-reaction of water electrolysis,oxygen evolution reaction（OER） requires a highly efficient electrocatalyst to elevate the reaction rate due to the intrinsic multiproton-coupled electron transfer.Because of the abundant,low toxic and excellent redox properties,iron has been paid more and more attention as electrocatalyst.Electrodeposition method develops as a basic method for preparing iron based catalyst due to the advantages of simple preparation and good reproducibility.Therefore,the analysis and summary of this method can be used as reference for the preparation of oxygen evolution catalysts.There are two types of electrodeposition：anodic and cathodic electrodeposition.The discrepancies in OER of the iron based catalysts prepared by these two methods,which provides a basis for the rational development of the new catalysts.
