In this paper, we report CoP nanowires supported on carbon cloth (CC) (CoP/CC) as a bifunctional electrode for hydrogen evolution reaction (HER) and supercapacitor. CoP/CC possess an excellent electrocatalytic performance for HER, with a Tafel slope of 56 mV/dec and a low overpotential of 68 mV to achieve a current density of 10 mA cm-2. Remarkably, the bifunctional CoP/CC used as electrode for supercapacitor exhibit a higher specific capacitance of 674 F g-1 at a scan rate of 5 mV s-1 and maintains long-life cycling stability, retaining 86% of the initial capacitance after 10,000 cycles. CoP/CC will be a promising candidate as electrode for HER and supercapacitor.摘要本文利用微波辅助水热法在碳布上快速合成了 CoP纳米线阵列(CoP/CC)双功能电极材料可用于析氢反应(HER)和超级电容器的电 极.CoP/CC用于Hm时展现了优越的电化学性能,其塔菲尔斜率为56 mV/dec.当电流密度为10 mA cm-2时,其电位低至68 mV. 值得注意 的是, CoP/CC也可用于超级电容器的电极.在扫描速率为5 mVs-1时, 其比电容高达674 F g-1.同时具有高的循环稳定性, 在循环10000次 后, 比电容仍然可以维持在初始值的86%.本文结果表明, CoP/CC可以作为HER和超级电容器电极的有力候选者.
