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. The dissolution, re-deposition or crystalline transforming of PbO2 took place during the electro-reaction process. In addition, the lifetime of the electrodes might be influenced by such dissolution and re-deposition.

Key words: Anode, Catalysis, Oxides, co-deposition, Ti/PbO2
