Abstract

This work reports the development of carbon sphere (CS) anchored cobalt tungstate (CoW) nanomaterial through simple and cost-effective method. To prepare CS, dextrose was used and with a simple displacement reaction CoW nanomaterial was obtained. The purity of all the synthesized material and their surface morphologies were analysed with the help of various spectroscopy techniques. While, electrochemical studies were performed to analyze the catalytic property of the material. The developed material was deposited on carbon sheet and electrochemical supercapacitor studies were performed in 1 M KOH electrolyte. The composite material exhibited maximum specific capacitance of 1124 F/g at 2 mV/s during cyclic voltammetry studies. The electrode material displayed greater stability during life cycle studies, and at the end of 6000 cycle of charge-discharge studies it exhibited 85 % retention in columbic efficiency. Thus, the material is recommended as electrode material for supercapacitor energy storage system.

钨酸钴纳米复合材料固载碳球增强超级电容器性能

本文报道了碳球（CS）锚定钨酸钴（CoW）纳米材料的简单、经济的制备方法。以葡萄糖为原料，通过简单的位移反应制备了纳米材料。利用各种光谱技术对合成材料的纯度和表面形貌进行了分析。同时进行了电化学研究，分析了材料的催化性能。将所制备的材料沉积在碳片上，并在1 M KOH电解液中进行了电化学超级电容器的研究。循环伏安法研究表明，复合材料在2 mV/s下的最大比电容为1124 F/g。电极材料在寿命周期研究中表现出更大的稳定性，在6000次充放电循环研究结束时，其哥伦比亚效率保持在85%。因此，推荐该材料作为超级电容器储能系统的电极材料。
