摘要:
采用热分解法制备了掺杂稀土La的Ti/SnO2-RuO2电极。对涂层材料作粉末衍射，分析涂层的组成及结构；对电极作强化寿命试验，测定其使用寿命；分别在硫酸、氯化钠溶液及两者混合溶液中作循环伏安曲线，研究电极的电化学性能。结果发现两种电极的合成颗粒结晶度低并且都主要由金红石结构TiO2 、RuO2和SnO2组成，掺杂稀土La能够提高电极的电化学性能和电极使用寿命。
Abstract:
The Ti/SnO2-RuO2 electrodes doped with La were prepared by the thermal decomposition method. The composition and structure of the coatings were analyzed with X-ray diffraction of the materials. Accelerated life test was carried out and their service lives were measured. Electrochemical properties were investigated by cyclic voltammetry (CV) in sulfuric acid solution, sodium chloride solution and their mixed solution respectively. Results show that the synthesized particles of the two electrodes exhibit low crystallinity and are mainly composed of rutile TiO2, RuO2 and SnO2. The doping of the rare earth La can improve the electrochemical performance and lifetime of the electrode.
