肼是较难氧化的物质,在酸性溶液中,在碳电极上电化学检测要求检测电位正于1.0V.用董绍俊等报道的方法,我们在750℃下对四苯基钴卟啉修饰玻碳电极热处理1h,制得修饰电极(简称HCME).首次发现这种HCME在酸性溶液中对肼具有良好的电催化氧化作用和极高的催化稳定性. 循环伏安实验发现,在pH2.5的磷酸缓 Hydrazine is more difficult to oxidize the material, in acidic solution, the electrochemical detection on the carbon electrode requires that the detection potential is at 1.0 V. With the method reported by Dong Shaojun et al., We modified tetraphenyl cobalt porphyrin at 750 ℃ The electrode was heat-treated for 1h to prepare a modified electrode (HCME for short) .The HCME was found to have good electrocatalytic oxidation and high catalytic stability to hydrazine in acidic solution for the first time.The cyclic voltammetry test found that at pH 2.5 Phosphate slow
