摘　　要：采用嵌入修饰法制得了碳纳米管负载铂修饰的浸蜡石墨电极，结果发现该修饰电极对H2O2的氧化还原都有良好的电催化性能。但对H2O2的还原有更好的催化性能。H2O2的浓度在2．5×10^-6～1×10^-4mol／L范围内呈现良好的线性关系；检出限为1．26×10^-6mol／L。A novel modified electrode was constructed by intercalating platinum-decorated carbon nanotube to graphite surface. The electrochemical reduction of hydrogen peroxide （H2O2） was studied on this modified electrode. The linear range for the determination of hydrogen peroxide is from 2.5×10^-6 to 1× 10^-4 mol/L and the detection limit is 1.26×10^-6 mol/L.
