英文摘要	运用电化学电位阶跃技术，在玻碳基底上制得FeCo合金纳米电催化剂（FeCo/GC）.XRD、SEM和TEM表征结果显示，合成的FeCo合金纳米粒子为单晶，呈立方体形貌，分布较均一，平均粒径65 nm，Fe和Co原子百分比约1:1.电化学测试结果表明，FeCo/GC具有比Fe/GC更高的电催化活性，对亚硝酸盐还原的活性是Fe/GC的4.7倍.FeCo/GC对氧还原也表现出优异的催化性能.; The FeCo alloy nanoparticles were electrodeposited on glassy carbon electrode by chronoamperometry and were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results showed that the shapes of FeCo nanoparticles were cubes with an average size of 65 nm. The atom ratio of Fe and Co is 1:1. As indicated from the pattern of selected area electron diffraction (SAED), the FeCo cubic nanoparticles were single crystal which belonged to body-centered cubic with an interval of 0.201 nm referring to the (110) facets of FeCo alloy. The FeCo cubic nanoparticles exhibited the enhanced electrocatalytic activities toward nitrite electroreduction and oxygen reduction reaction.; 新世纪优秀人才支持计划（No. NCET-10-0715），高等学校全国优秀博士学位论文作者专项资金（No. 201126）和浙江省重中之重学科开放基金项目(No. 20090503)资助; 作者联系地址：厦门大学固体表面物理化学国家重点实验室，化学化工学院化学系，福建厦门 361005; Author's Address: State Key Laboratory of Physical Chemistry of Solid Surfaces, Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, Fujian, China; 通讯作者E-mail：shpchen@xmu.edu.cn
