摘　　要：在150μm的铱电极上,采用高电位氧化和低电位还原的方法制备纳米多孔Ir/IrOx电极,并用扫描电镜、循环伏安方法对其结构和电极的电化学进行表征。纳米多孔Ir/IrOx电极用于过氧化氢的检测,灵敏度高,线性范围宽,分别为10～590μmol/L和2～60 mmol/L,检测限为2.77μmol/L。实验结果令人满意。Nano porous Ir/IrOx electrode was successthlly prepared on 150 υm iridum electrode by using high potential oxidation and low potential reduction methods, meanwhile scanning electron microscope and cyclic voltammetry were used to evaluate its structure and electrochemistry. The application of nano porous Ir/IrOx electrode in hydrogen peroxide detection has high sensitivity and wide linear range which is 10～590υmol/L and 2～60 mmol/L, respectively. And its detection limit is 2.77 υmol/L. The results are satisfactory.
