【摘要】 本文用SEM和EDS研究了Ti／SnO2＋RuO2＋MnOx／MnOx电极的表面形貌和表面元素相对含量，考察了电极在20％H2SO4中的使用寿命，并用双位垒模型讨论了该电极的电化学性能，结果表明电极具有优良的电化学性能和较长的使用寿命．更多还原

【Abstract】 A new kind of electrode, Ti/SnO2+RuO2+MnOx/Mnox, is reported in thepresent paper. The surface morphology and the composition of semi-quantitative analysis of the electrode was carried out by meams of SEM and EDS. The lifetime of electrode reached 34 hours at a currelit density of 4 A/cm2 in 20% H2SO4. The dual barrier model is used to interpret the experimental results on the electrode, which was proved to have better electrochemical propertles and longer lifetime.更多还原
