基于碳纳米管-FexOy复合材料电极的电化学性能
Electrochemical Property of Carbon Nanotubes-FexOy Nanocomposite Electrode
摘要
Abstract
CNTs-FexOy nanocomposite film was employed as the electrode,and its electrochemical performance was investigated in both water solution and gel electrolyte.Carbon nanotube(CNTs) film was first fabricated by chemical vapor deposition,on which FexOy vapor was condensed by ultrasonic spray pyrolysis to form the CNTs-FexOy nanocomposite film electrode.After the electrode morphology analysis,the electrochemical property including cyclic voltammetry,chronopotentiometry and AC impedance were measured.The results show that the composite electrodes exhibited enhanced capacitive behavior relative to pure CNTs.However,over loaded FexOy in CNTs-FexOy composites deteriorated their capacitive performance.And the sample FexOy deposited for 10min demonstrated the optimized electrochemical capacitive properties,with the highest specific capacitance(Csp) in gel electrolyte of 102.8 F·g^-1 and lowest interface charge transfer resistance.关键词
