| 中文摘要 | a composite film containing heteropolyanion was fabricated on gold by attaching the keggin-type heteropolyanion, pmo12o403- on a 4-aminothiophenol sam via au-s bonding. reflection ftir, cyclic voltammetry and xps were used for the characterization of the composite film. reflection ftir studies indicate that there is some coulombic interaction between pmo12o403- and the surface amino group in the composite film, which greatly improves the film stability and prevents effectively the destructive intermolecular aggregation. the composite him shows three reversible redox couples within the ph range ph less than or equal to 7.0, attributed to three two-electron and two-proton electrochemical reduction-oxidation processes of pmo12o403-. compared with pmo12o403- in the solution, the pmo12o403- of the composite film electrode can exist in a larger ph range, and shows smaller peak-to-peak separation, and more reversible reaction kinetics. moreover, the composite him obtained shows a good catalytic activity for the reduction of bro3-.
