摘要

以六水三氯化铁为铁源,采用水热法合成了高活性Fe2O3@Ni复合电极材料。运用X射线衍射、拉曼光谱、扫描电镜对产物的物相及微观形貌进行了表征。结果表明在泡沫镍表面原位合成的氧化铁是由直径约为5~20 nm的纳米丝交织而成的,从而构成有序三维网状结构,分布均匀紧密。采用循环伏安测试、恒电流充放电测试研究了Fe2O3@Ni复合电极材料的电化学性能,Fe2O3@Ni复合电极呈现赝电容的特性,在电流密度为1 A/g时,Fe2O3@Ni复合电极材料比电容可达532 F/g。

Abstract

Fe2O3@Ni composite electrode material with high activity was synthesized by hydrothermal method using FeCl3·6H2O as iron source.The phase and microstructure of the products were characterized by X-ray diffraction,Raman spectroscopy and scanning electron microscopy.The results showed that the iron oxide synthesized in situ on the surface of the nickel foam was interwoven by nanowires with a diameter of about 5~20 nm,which constituted an ordered three?鄄dimensional network structure with uniform distribution.The electrochemical properties of Fe2O3@Ni composite electrode materials were studied by cyclic voltammetry and galvanostatic charge-discharge tests,and the Fe2O3@Ni composite electrode exhibited the characteristics of pseudocapacitance.The Fe2O3@Ni composite electrode material showed a specific capacitance of 532 F/g at a current density of 1 A/g.
