摘要：

在含镍离子和铜离子的溶液中用循环伏安法在玻碳电极(GCE)表面电化学沉积一层镍-氧化镍及铜-氧化亚铜纳米粒子 ( Ni /NiO、 Cu/Cu2O)，在-0.3 V电位条件下，该传感器能催化还原H2O2。用安培法测定H2O2的响应电流与浓度在2.5×10-6 ~2.8×10-3 mol/L范围内呈线性关系，研究了各种实验条件对H2O2传感器性能的影响。该传感器制作简单， 使用寿命长，在实际试样的回收率测定中，结果满意。

Abstract:

A sensor was fabricated by means of electrodeposition nickel-nickel oxide and copper-cuprous oxide on a glass carbon electrode in the solution of Ni2+and Cu2+. It was based on the catalytic reduction of H2O2 by nickel-nickel oxide and copper- cuprous oxide at a certain applied potential of -0.3V. The response current was linearly changed with the concentration of H2O2 in a range from 2.5×10-6 to 2.8×10-3 mol/. The effects of assay conditions on performances of hydrogen peroxide sensor were studied. The preparation of the sensor is  simple and it can be used for a long time. The sensor was used for the determination of real samples containing hydrogen peroxide with satisfactory recovery and result.

Key words: nickel-nickel oxide,copper-cuprous oxide,cyclic voltammetry,amperometric,electrodeposition
