摘　　要：采用一步电沉积在柔性胶带石墨烯电极(GTE)上制备了CoP,并研究了其对葡萄糖的电催化性能。实验结果表明:CoP/GTE对葡萄糖有良好的电催化作用,且葡萄糖在该电极上的氧化还原反应受电化学表面控制。同时,计时电流法(CA)研究表明:CoP/GTE对葡萄糖氧化具有高效的催化作用,线性检测范围为0~3mmol/L。另外,在0~5 mmol/L检测范围内,对葡萄糖产生的响应电流没有受到电极表面活性位点的催化限制,表明了制备的电极具有良好的表面控制。In this paper, one-step electrodeposition was used to prepare Co P on a flexible tape graphene electrode(GTE), and its electrocatalytic performance for glucose was studied. The results showed that Co P/GTE has a good electrocatalytic effect on glucose, and the redox reaction on the electrode is controlled by the electrochemical surface. Meanwhile, CA studies revealed that the Co P/GTE performed well by attaining a wide linear response range of glucose from 0 to 3 mmol/L. In addition, no“catalytic saturation”occurred during the 0~5 mmol/L glucose test, which also shows that the prepared electrode has good surface control.
