| 中文摘要 | in this paper a carbon fibre (cf) microelectrode modified with the 2:18-molybdodiphosphate anion by simple adsorption is described and its electrochemical behaviour is reported. the 2:18-molybdodiphosphate anion (alpha-p2mo18o626-), which is a dawson structure, undergoes five successive multielectron reductions in acidic solution. the first three redox waves correspond to the two-electron process, and the last two waves are four-electron and six-electron processes respectively. on the basis of the experimental results it is shown that the electrode process of alpha-p2mo18o626- on the cf electrode in acidic solution is simultaneously controlled by the diffusion and adsorption of alpha-p2mo18o626- anions. when the concentration of the alpha-p2mo18o626- in the solution is reduced, the electrode process mainly exhibits non-diffusion-controlled behaviour, and the diffusion-limited process takes over as the concentration of alpha-p2mo18o626- becomes higher. the cf electrode modified with a thin film of alpha-p2mo18o626- exhibits very good stability and redox behaviour in aqueous acidic solution. the alpha-p2mo18o626- is reduced to heteropoly blue, with an accompanying protonation process. the addition of more than six electrons to the alpha-p2mo18o626- anion in an aqueous solution does not result in its decomposition. the result obtained is not the same as that reported previously. |
