Carbon supported oxide composite electrocatalysts were prepared through the absorption of Vulcan XC-72R carbon on Sb3+,Ce3+-doped SnO2 precursors which were obtained by sol-gel method.The changes of impedance values of Sb3+ and Ce3+-doped SnO2/C electrodes under the different potential and Phenol concentration were measured by electrochemical impedance spectroscopy（EIS）.The results indicate that the reaction resistance becomes lower with the increasing voltage and has higher impedance with the increasing concentrations. 溶胶-凝胶法 苯酚 电化学交流阻抗法 sol-gel method phenol AC impedance method 10.14188/j.1671-8836.2011.01.005 O657.1 国家自然科学基金（20071026）资助项目 2011-01-01 2021-04-01 1 57
