自从化学修饰电极问世以来,在电极反应过程、电极效应以及扩展修饰薄膜类型方面进展较快。目前研究较多的是聚合物薄膜修饰电极,由于结构和化学性能的特点,对无机物修饰电极的研究也已引起重视。杂多酸具有很好的氧化还原性能,而且可通过改变化学组成的方法使杂多酸的氧化还原电位在很宽范围内变动。杂多酸可发生多电子还原反应形成“杂多蓝”,所以杂多酸或其盐类修饰在电极上有可能发生电催化和电色效应。目前杂多酸修饰电极的报道甚少。本文研 Since the advent of chemically modified electrodes, progress has rapidly progressed in electrode reaction processes, electrode effects, and the types of extended trim films. At present, most researches focus on polymer film modified electrodes. Due to their structural and chemical properties, studies on inorganic modified electrodes have also drawn great attention. Heteropolyacids have good redox properties, and the redox potential of heteropolyacids can be varied within a wide range by changing the chemical composition. Heteropoly acid can occur multiple electron reduction reaction to form “heteropoly blue”, so heteropolyacid or its salt modified electrode may have electrocatalysis and electrochromic effect. Heteropoly acid modified electrodes currently reported little. This article research
