中文摘要：

利用热分解法制备了EuBr3、Eu（NO3）3、EuC13、Eu（ClO4）3、Eu（AC）3掺杂Sb-SnO2/Ti电极,通过对乙醇氧化和对模拟废水（甲基橙、亚甲基蓝）的降解,研究电极的电催化性能.通过循环伏安法,X射线衍射（XRD）仪,扫描电子显微镜（SEM）,X射线光电子能谱（XPS）等对电极进行了表征.结果表明,不同Eu盐掺杂Sb-SnO2/Ti电极对不同体系表现出不同催化性能.Eu（ClO4）3掺杂电极对降解甲基橙有最好的效果,EuC13掺杂对降解亚甲基蓝表现最佳,而对于电催化氧化乙醇体系,Eu（YO3）3掺杂电极表现出了最高的催化活性.

英文摘要：

EuBr3,Eu（NO3）3,EuCl3,Eu（ClO4）3,Eu（AC）3 doped Sb-SnO2/Ti electrodes were prepared by thermal decomposition.The properties of electrodes for the oxidation of ethanol and the electro-catalytic decomposition of a model pollutant （methyl orange,methylene blue） were investigated.Electrodes were characterized by cyclic voltammetry,X-ray diffraction,scanning electron microscope,and X-ray photoelectron spectroscopy.It is suggested that various Eu salts doped Sb-SnO2/Ti electrodes show different catalytic properties.Eu（ClO4）3 doped electrodes show the best effect for degradation of methyl orange,EuC13 doped electrodes provide the best degradation of methylene blue,and as for electric catalytic oxidation ethanol,Eu （NO3）3 doped electrodes show the highest catalytic activity.
