| 中文摘要 | in this paper, an organic-inorganic composite film of heteropolyanion was formed by attaching a keggin-type heteropolyanion, siw12o404-, on carbon electrode surface derivatized by 4-aminophenyl monolayer. the composite film thus grafted on carbon electrode surface has good stability because of the ionic bonding character between siw12o404- and surface aminophenyl groups. x-ray photoelectron spectroscopy, scanning tunneling microscopy, and cyclic voltammetry were used to characterize the composite film. compared with siw12o404- electrodeposited on a bare glassy carbon electrode (gce), the composite film gives three more sharp and well-defined redox couples attributed to two one- and two-electron processes, and the analyses of the voltammograms of siw12o404- anion in the composite film modified on gce shows that its surface coverage is close to a closest packing monolayer. stm characterization shows that a two-dimensional order heteropolyanion monolayer was formed on hopg substrate. the composite film provides a favorable environment for electron and proton transfer between siw12o404- ion and electrode surface, which may make it suitable for various applications in sensors and microelectronics devices. |
