| 摘 要： | 采用循环伏安法,研究双-Keggin型含铕硅钼钨多金属氧酸盐(Eu(SiMo4W7)213-)水溶液的电化学性质,结果表明,在0.7~-0.45V的电位区间内,Eu(SiMo4W7)213-呈现了两对准可逆的单电子氧化还原峰,峰电位随着溶液pH值的升高而线性负移,催化活性实验显示,在酸性溶液中该化合物对NaNO2和H2O2的还原反应具有良好的催化作用.

| Abstract: | The electrochemical behavior of the Eu(SiMo_ 4 W_ 7 )_ 2 ~ 13- in aqueous solution has been studied using cyclic voltammetry. In the potential range between 0.70~-0.45 V vs SCE, the anion in pH= 3.84 aqueous solution undergoes two one-electron redox cycles from the molybdate-oxo framework, which linear shifts of redox peaks toward negative direction occur as the pH of solution increases. The complex shows good electrocatalytic activity to the reduction of nitrite and catalase. |
