文章以KB600型活性炭和少量氯铱酸为原料,分别采用共沉积法和还原氧化法制备了碳载氧化铱电极材料,通过循环伏安测试和恒流充放电测试对比分析了材料的电化学性能。其中,还原氧化法制备的碳载IrO2电极材料的比电容量高达389.7 F·g-1,具有较好的应用前景。

In this work, the electrode materials of IrO2 have been successfully synthesized by a chemical co-precipitation route and reduction-oxidation method, respectively, using KB 600 active carbon and H2IrC16 as raw materials. Cyclic voltammogram（CV） and galvanostatic charge-discharge（GC） were performed to analysis electrochemical performance. The specific capacitance of frO2 obtained by reduction-oxidation method is up to 389.7 F g 1, which shows that lrO2 will be promising materials in supercapacitor applications.
