【摘要】 合成了磷钼钒类杂多酸，采用电化学方法首次在导电基体玻碳电极上研制了磷钼钒类杂多酸－聚吡咯薄膜修饰电极，该电极性能稳定、经久耐用．对膜修饰电极的电化学行为进行了表征，研究了膜修饰电极对酸性水溶液中的氯酸根、溴酸根、碘酸根、亚硝酸根、三价铁离子、过氧化氢等物质的电催化还原作用，初步探讨了电催化反应机理．更多还原

【Abstract】 Molybdovanadophosphoric heterpoly acids were synthesized, and molybdovanadophosphoric heterpoly acids polypyrrole film modified glassy carbon electrodes are prepared by electrochemical deposition. Its voltammetric behaviour are studied. The film modified electrodes have good stability and high electrocatalytic activity on the reduction of ClO - 3, BrO - 3, IO - 3, NO - 2, Fe 3+ , H 2O 2 in acidic aqueous solution. The catalytic process is described.更多还原
