摘要

采用水热法一步制备了氧化铁(Fe2O3)/碳纳米管复合材料,并对制得的Fe2O3/碳纳米管复合材料的形貌、结构进行了表征。对Fe2O3/碳纳米管复合材料的循环伏安特性和电化学性能进行了研究。七水合硫酸亚铁(FeSO4·7H2O)用量为200mg制得的Fe2O3/碳纳米管复合材料,在放电电流密度为0.5A/g条件下,Fe2O3/碳纳米管复合材料的比电容高达618F/g,在500次循环之后电容保持率可达56.8%。

Abstract

A type of Fe2O3 supported carbon nanotubes was prepared by hydrothermal method,and the morphology,structure and thermal stability of obtained materials were characterized.Moreover,the cyclic voltammetry curves and electrochemical impedance spectroscopy were measured.In the case of Fe2O3/carbon nano-tubes materials with 200mg of FeSO4·7H2O in-feeding,when the discharge current density was 0.5A/g,the specific capacitance of material was 618F/g,and maintaining as 56.8% after 500 cycles.
