| 摘 要： | 采用热分解和电沉积的方法制备了稀土元素Y掺杂Ti/SnO2+MnOx/PbO2耐酸阳极.用XRD、SEM表征了电极的物相和表面形貌,用CV、EIS测定了电极的电化学性能,并研究了Y掺杂对电极在强酸性溶液中使用寿命的影响.结果表明:Y以Y2O3的形式与SnO2形成半导体固溶体,使电极在高电流密度(4 A/cm2)下的预期使用寿命达到70 h;同时该电极的析氧电位高达2.1 V,且电极表面呈蘑菇状,电催化性较好,Ti/SnO2+Y2O3+MnOx/PbO2电极是一种较理想的耐酸阳极材料.

| Abstract: | Acid-proof Ti/SnO2+MnOx/PbO2 anode doped with rare earth Y was prepared by thermal decomposition method and electrodeposited method. The surface characterization of the electrode was characterized by scanning electron microscopy(SEM) and the element composition of layers was analyzed with X-ray Diffraction(XRD). The electrode electrochemical properties were analyzed with Cyclic Voltammogram (CV) and Electrochemical Impedance Spectroscopic (EIS).The influence of Y doping on the service life of the electrode ... |
