| 中文摘要: |
| 采用溶胶凝胶法制备了Sb掺杂Ti/SnO2 电极,通过XRD,SEM,EDS及电化学测试、氧化物总量测试、加速寿命测试等技术手段,研究了Sb的掺杂对电极结构、形貌、电催化性能、使用寿命的影响。结果表明:Sb的掺入能有效改善电极的表面晶体结构和形貌,降低电极的苯酚氧化电位和液界电阻,提高电极的电催化效率;当制备的溶胶中锡锑比为9暶1时,制得的电极表面形貌平整、致密,稳定性和电催化效果最好。 |
| 英文摘要: |
| Sb-doped Ti/SnO2 electrodes were prepared using sol-gel method. The impacts of doping Sb on the properties of the Sb-doped Ti/SnO2 electrodes, which mainly included structure, morphology, electro-catalytic performance and service life, were investigated with some characterizing methods such as X-ray diffraction(XRD),scanning electron microscopy(SEM),energy dispersive spectrometer(EDS), electrochemical methods, total residual oxide detection(TRO), accelerated life test and so on. It was found that Sb doping level could improve effectively the surface crystal structure and morphology of Ti/SnO2 electrodes, lower the oxidizing potential for phenol and liquid junction resistance of electrodes, and aggrandize electro-catalytic efficiency. When the optimalizing doping level is Sn/Sb molar ratio of 9:1 in the sol, the prepared electrodes possess the smoothest and most compact surface morphology, the best stability and theoptimal electro-catalytic activity. |
