| 摘 要： | 自1990年9月Kratschmer等报导了C_(60)的常量制备和提纯以来,有关C_(60)及其他富勒炭分子(Fullerens)的研究报导与日俱增,成为近三年来最为活跃的研究领域之一.由于C_(60)的特殊结构,在电化学行为上也表现出十分独特的反应性质,如容易实现多电子氧化还原反应,可逆加氢及能形成离子嵌入电极材料等.本工作采用微电极方法研究了C_(60)稳态极化行为,测定了C_(60)的扩散系数和反应电子数,并通过现场紫外可见光谱电化学方

| Abstract: | The electroreduction of C_(60) was investigated by microelectrode voltammetry and in-situ optically transparent thin layer electrode technique(OTTLE). From the mea-surements of steady-state polarization curves and the absorbance dependence of C_(60) on reduction potentials, it is found that the electroreduction of C_(60) occurs in a succes-sive three step one-electron reduction. The diffusion coefficient and standard equilib-rium potential were evaluated to be 5.3×10~(-6)cm~2·s~(-1) and -0.40±0.02 V(vs. Ag/AgCl) respectively. |
