SiCo（H₂O）W₁₁O₃₉^6-在玻碳电极上的多层膜修饰及电化学行为

摘要: 制备了包含杂多酸SiCo(H₂O)W₁₁O₃₉^6- (SiCoW₁₁)和阳离子聚电解质——聚二烯丙基二甲基氯化铵(PDDA)的多层膜修饰电极,用循环伏安法研究了SiCoW₁₁在酸性水溶液中的电化学行为及p^H的影响,初探了反应机理.逐层的循环伏安行为表明膜的增长均匀,峰电流随膜层数的增加而增加,与其在溶液中的氧化还原行为相比,多层膜中的SiCoW

Abstract: The electrochemical behavior of SiCo（H₂O）W₁₁O₃₉^6- (SiCoW₁₁) heteropolyanion in acidic aqueous solutions is studied. The effect of solution pH on the electrochemical behavior of SiCoW₁₁ is discussed and the mechanism concluded. New multilayer films composed of heteropolyanion (SiCoW₁₁) and cationic polymer poly （diallyldimethylammonium chloride） were fabricated. The electrochemical behaviors were investigated. Cyclic v...
