| 摘 要： | 借助于可换盘旋转环盘电极在含Ce[3+]酸性溶液中比较了n-TiO2电极上载多孔铱层前后的竞争光氧化过程,观察到当铱以高度分散的针状多孔透光层在TiO2电极表面分布时能够催化Ce[3+]的光电化学氧化,并据此讨论了催化光电化学反应的基本前题。

| Abstract: | The competitive photooxidn. was studied of Ce3+ on the surface of a n-TiO2 electrode before and after deposition of porous Ir needles by using a rotating ring-disk electrode with interchangeable disk. Highly dispersed porous layer composed of Ir needles could catalyze the photooxidn. of Ce3+. Basic postulates of catalysis of photoelectrochem. reactions are discussed. |
