研究了电化学方法制备的聚２，５－二甲氧基苯胺薄膜电极（Ｐ２５ＤＭＡｎ／Ｐｔ）对水溶液中儿茶酚的电催化作用，以及影响催化作用的主要因素，结果表明，在酸性较强的水溶液中，在较充的浓度范围内（儿茶酚的浓度为１×１０￣－１～５×１０￣－５ｍｏｌ／Ｌ）均有很好的电催化作用，催化电流与儿茶酚浓度呈良好的线性关系。
The electrocatalytic activity of poly (2,5-dimethoxyaniline) thin film electrode (P25DMAn / Pt) prepared by electrochemical method on the electrocatalysis of catechol in aqueous solution and the main factors affecting the catalytic effect were studied. The results showed that under the conditions of high acidity , The electrocatalytic activity was good in the range of concentration (1 × 10 ~ -1 ~ 5 × 10 ~ -5 mol / L catechol concentration), the catalytic current and catechol concentration A good linear relationship.
