摘要/Abstract

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.

关键词: FeCo合金, 立方体, 电催化, 亚硝酸盐还原, 氧还原

Abstract: 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.

Key words: FeCo alloy, cube, electrocatalysis, nitrite reduction, oxygen reduction reaction
