| 中文摘要 | in this paper the electrochemical properties of isopolymolybdic anion thin film modified carbon fibre (cf) microelectrode prepared by simple dip coating have been described. the modified electrode shows three couples of surface redox waves between + 0.70 and - 0.1 v vs. sce in 2 m h2so4 solution with good stability and reversibility. the ph of solution has a marked effect on the electrochemical behaviour and stability of the film, the stronger the acidity of electrolyte solution is, the better the stability and reversibility of isopolymolybdic anion film cf microelectrode will be. the scanning potential range strongly influences on the electrochemical behaviour of the film. the isopolymolybdic anion film prepared by the dip coating resulting a monolayer with estimated surface concentration (f) 2.8 x 10(-11) mol cm-2. from the half-peak widths and peak areas of the surface redox waves of the film electrode, the first three surface waves are corresponding to two-electron processes. the electron energy spectra show the products by six electrons reduction are a mixture of mo(vi) and mo(v) species. the electrochemical reaction of the isopolymolybdic anion monolayer can be expressed as mo8o264- + mh+ + 2ne half arrow right over half arrow left [hmmo8-2n(vi)mo2n(v)o26](4,2n-m)-n = 1, 2, 3; m = 2, 5, 7. |
