| 摘 要： | 双-Keggin结构取代型稀土多金属氧酸盐K10H3Eu（SiMo4W7O39）2].XH2O（简写为EuSiMo4W7）在水溶液中可进行一系列单电子和两电子的可逆还原过程,产生具有催化活性的杂多蓝,因此,该类化合物是良好的氧化剂和催化剂。采用循环伏安法研究EuSiMo4W7水溶液的电化学性质、扫描速度及溶液pH均对EuSiMo4W7的电化学性质有所影响,同时考察该物质对卤酸根离子还原反应的催化作用,结果表明：EuSiMo4W7对IO3-的催化作用强于对BrO3-的催化作用,而对ClO3-基本上不起催化作用,可见,EuSiMo4W7对3种卤酸根离子还原反应的催化作用按照ClO3-、BrO3-、IO3-的顺序依次增强。

| Abstract: | The double-Keggin polyoxometalate K10H3Eu（SiMo4 W7O39）2]·XH2O（abbreviated as EuSiMo4W7） undergo a series of one-electron and two-electron redox processes in the aqueous solution,which was generated heteropolyblue with electrolytic activities.It may provide a well material as oxidant and electrocatalyst.In the article,the effects of scan rate and pH on the electrochemical behavior of EuSiMo4W7 were studied.The reduction to XO-3（X=Cl,Br,I） by double-Keggin polyoxometalates EuSiMo4W7 was investigated by cyclic voltammetry.The results reveal that EuSiMo4W7 can afford electrocatalytic reduction to IO-3 better than that of BrO-3,but almost no reduction to ClO-3.The activity of reduction is IO-3 BrO-3 ClO-3. |
