通过对 RuO_2电极在不同烧结温度和电解时间条件下表面形貌的观察与 AES分析,推断出RuO_2 电极的活性中心是氧结构空位,在电极表面凸处氧结构空位较多;随着电解的进行,电极活性降低,氧结构空位减少,但在凸处的比在凹处的减少较多,故认为反应点较多地集中在表面凸处。 By observing the surface morphology and AES analysis of RuO_2 electrode under different sintering temperature and electrolysis time, it is inferred that the active center of RuO_2 electrode is the oxygen vacancy and the oxygen vacancies are more on the surface of the electrode. With the progress of electrolysis , The electrode activity decreased, oxygen structure vacancies decreased, but in the convex than the reduction in the recess more, so that the reaction point is more concentrated in the surface convex.
