  • 摘要: 使用电镀法制备了含SbO2-SnO2中间层的TiO2/SbO2-SnO2/SnO2-Sb-CeO2电极.采用扫描电镜（SEM）、X射线衍射仪（XRD）、电化学工作站等分析仪器研究了中间层对电极表面结构、组分和电化学性能的影响.在大电流密度下测定了电极的强化使用寿命，并以酸性黑10B为模拟污染物研究了电极的电催化性能.研究结果表明，SbO2-SnO2中间层可有效改善电极表面结构，从而影响电极的寿命和催化性能.相比不含中间层的TiO2/SnO2-Sb-CeO2电极，加入SbO2-SnO2中间层后，电极表面的活性层更加致密和平整，寿命增加了10倍，对酸性黑10B的降解速率提高了一倍.
    Abstract: Electrodes with SbO2-SnO2 intermediate layers were prepared via electrochemical deposition. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and electrochemical techniques of the electrodes were used to investigate the morphology, phase composition and electrochemical performance Accelerated service life test was conducted under a high current density in 1 mol·L-1 H2SO4 solution, and the acid black 10B was used as a model pollutant to investigate the electrocatalytic activities of different electrodes. The results demonstrated that the SbO2-SnO2 intermediate layer enhanced the service life and electrochemical performance. The surface of electrode become smoother and denser when SbO2-SnO2 intermediate layer was added. The lifetime and degradation rate of electrode with SbO2-SnO2 intermediate layer was 10 times and 1 time higher than that of TiO2/SnO2-Sb-CeO2 electrode, respectively.
