Abstract The mesoporous SnO₂ support was prepared by hydrothermal method using cetyltrimethylammonium bromide (CTAB) as template, and the catalyst supported was prepared by Adams method, and the dosage of IrO₂ was 40% (mass fraction). The structures and properties of the supporters and catalysts were characterized and analyzed by BET, XPS, XRD, and TEM. Then, Sb and Co doped SnO₂ carriers were used to synthesize the catalyst to explore its influence on the structure and performance of the supporters and catalysts. The results show that when the hydrothermal reaction time is 24 h, the obtained carrier is most beneficial to the catalyst and obtain the optimal performance. Simultaneously, Sb and Co doped SnO₂ supporters are used to synthesize the catalyst, and the effects of ion valence state and ion size on the structure and properties of the supporters and catalysts are investigated. Doping with Sb and Co can effectively improve the proton transfer of SnO₂. When Sb is doped with SnO₂, the electrochemical cycle performance of the catalysts continues to increase. When the doping amount is 20%(mole fraction, the same below), the catalyst obtains the best electrochemical performance; and with the increases of Co doping, the electrochemical cycle performance of the catalysts is reduced. When the doping amount is 5%, the electrochemical active area is the largest, the voltammetric charge Q^* is equal to 1 478 mC·(cm²·mg)^-1. Finally, by testing the performance of single cell with different doping elements to research: Co doped SnO₂ has the greatest improvement on the performance of IrO₂ single cell. The anodic overpotential for oxygen evolution was 1.884 V under the test conditions of 1.0 A/cm². The performances of the doped catalyst are directly related to the valence state and ion size of the doped ion. The larger the valence difference between ions, the higher the catalytic performance of the catalysts. The ionic sizes of Sb are larger than that of Sn⁴⁺, and the performance improves with the increase of doping amount; and the average ionic size of CO is smaller than that of Sn⁴⁺, and the perfo-rmance decreases with the increase of doping amount.
