| 摘 要： | 采用阳极共沉积的方法制备了Fe和Co掺杂Ti/PbO2电极。 用XRD、SEM及循环伏安法研究了Fe和Co掺杂对Ti/PbO2电极的影响。 结果表明，掺杂Fe和Co的Ti/PbO2电极与纯Ti/PbO2电极相比，虽然形貌变化很小，但在结构和性质上发生了改变。 Co掺杂可提高电极的析氧活性，PbO2 电极涂层在电化学过程中存在溶解和重新沉积或者晶型转化的现象。 这种Pb2+的溶解与再沉积可能会影响电极材料的寿命。

| Abstract: | Ti/PbO2 electrodes doped with Fe or Co were prepared by an electro-codeposition method.The effects of the Fe or Co on Ti/PbO2 electrodes were investigated by the X-ray diffraction(XRD),scanning electron microscope(SEM) and cyclic voltammetry(CV).Compared with the pure Ti/PbO2 electrode,the morphology of Ti/PbO2 electrode doped with either Fe or Co remained nearly unchanged while their structures and performances were varied.The activities of oxygen evolution reaction(OER) were improved in Co doped electrode... |
