| Abstract: |
| 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. |
