| 摘 要： | 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。

| Abstract: | RuO2 electrodes prepared at various sintering temperatures andelectrolysed for various electrolytic times are studied by means of SEM and AES methods. The results show that the active sites of RuO2 electrode for oxygen evolution are oxygen-deficient structures which at convex spot is more than that at concave spot. As the activation of RuO2 electrode decreases, oxygen-deficient structures at both convex spot and concave spot decrease But the reactive site is mainly centralized at convex spot. |
