中文摘要：

采用溶胶凝胶法制备了Ni2＋掺杂的Ti／SnO2-Sb2O5电极，并通过XRD、SEM、EDS、苯酚降解、加速寿命实验等技术手段．研究了Ni2＋的掺杂对电极的结构、形貌、电催化性能及稳定性的影响。结果表明：Ni2＋的掺人细化了SnO2晶粒，增大了电极的比表面积，改善了电极表面的龟裂程度，提高了电极的导电性能；相对于Ti／SnO2．Sb2O5电极Ni2＋的掺入将苯酚完全降解的时间缩短为原来的40％，将电极的使用寿命提高为原来的4．8倍。

英文摘要：

Sol-gel method was employed to prepare NiZ＋-doped Ti/SnO2-Sb2O5 electrodes. The impacts of doping Ni2＋ on the performances of the as-prepared electrodes, which consisted of structure, morphology, electro-catalytic performance and electrode stability, were investigated though some measurements including X-ray diffraction （XRD）, scanning electron microscopy （SEM）, energy dispersive spectrometer （EDS）, phenol decomposition test, accelerated life test and so on. Experimental results indicated that Ni2＋-incorporation level can enhance SnO2 grain refinement, raise the specific surface area of the electrode, improve the electrode interface crack and advance the electrical conductivity; compared with pure Ti/SnO2-Sb2O5 electrodes, NiZ＋-doped level decreases the phenol completely degradation time into 40%, and increase the electrode service life into 480%.
