摘　　要：电解水制氢技术作为当下最有效的制氢技术之一,低成本、高性能的电催化剂是提高电解水效率的理想选择。本文采用了一步电沉积法在泡沫镍上制备镍、铁、锰三元纳米片(NiFeMn)作为析氧反应(OER)电催化剂。当电流密度为20mA·cm^(-2)时,过电位达到297mV,Tafel斜率达到了143.2mV·dec^(-1),经过了12小时的I-T测试后,其电流密度为86mV·cm^(-2),表明该材料具有较好的稳定性和活性。NiFeMn纳米片良好的OER性能可能是由于其高的电化学活性表面积,为OER反应提供了更多的活性位点。As one of the most effective hydrogen production technologies,low cost and high performance electrocatalyst is an ideal choice to improve the efficiency of water electrolysis.In this paper,nickel,iron and manganese ternary nanosheets(NiFeMn)were prepared on nickel foam by one step electrodeposition as electrocatalyst for oxygen evolution reaction(OER).When the current density is 20 mA·cm^(-2),the overpotential reaches 297 mV and the Tafel slope reaches 143.2 mV·dec^(-1).After 12-hour I-T test,the current density is 86 mV·cm^(-2),indicating that the material has good sta-bility and activity.The good OER performance of NiFeMn nanosheets may be due to their high electrochemically active surface area,which provides more active sites for OER reaction.
