摘要

优化的电极是诸如超级电容器之类的基于能量的应用的主要要求。本文讨论了由氧化石墨烯（GO）、聚苯胺（PANI）和氧化锌（ZnO）组成的三元复合材料作为超级电容器电极材料的结构和电化学性能。为了实现这一点，采用了（i）改良的鹰嘴豆泥法（ii）原位聚合法和（iii）水热法。这些材料之间的协同效应提供了具有多孔结构和高比电容的高效电极材料。通过循环伏安法、恒电流充电和放电测量以及在6M KOH电解质中的电化学阻抗谱分析了样品的电化学性质。三元复合材料在1 A g−1时表现出278 F g−1的最高比电容。

Enhancement of the Carbon Content and Electrochemical Performance by Decorating Zinc Oxide over Graphene Oxide/Polyaniline Composite

An optimized electrode is the main requirement for energy based applications such as supercapacitor. In this work, ternary composite made up of graphene oxide (GO), polyaniline (PANI) and zinc oxide (ZnO), as an electrode material for supercapacitor was discussed with its structural and electrochemical properties. To attain this, (i) modified hummers' method (ii) in-situ polymerization method and (iii) hydrothermal method were employed. Synergistic effects between these materials provided efficient electrode materials with porous structure and high specific capacitance. The electrochemical properties of the samples were analysed by cyclic voltammetry, galvanostatic charge and discharge measurements and electrochemical impedance spectroscopy in 6 M KOH electrolyte. The ternary composite exhibited the highest specific capacitance of 278 F g−1 at 1 A g−1.
