Novel sensing materials have been formed by decorating polyaniline conducting polymers with atomic gold clusters where the number of atoms is precisely defined. Such materials exhibit unique electrocatalytic properties of electrooxidation to aliphatic alcohols, although analytes with other functional groups have not been studied. This paper reports a study of cyclic voltammetric patterns obtained with bi-atomic gold nanocomposite response to analytes with other functional groups for sensor applications. Principal component analysis shows separation among normal-propanol, iso-propanol and ethyl formate/ethanol groups. Indirect sensing of ethyl formate is demonstrated by electrooxidation of the product upon hydrolysis in alkaline medium. Voltammograms of ethyl formate are studied in gaseous phases.

使用原子金装饰的聚苯胺电极间接检测下部脂肪族酯。

通过用原子金团簇装饰聚苯胺导电聚合物来形成新型传感材料，其中原子团数得到精确定义。尽管尚未研究具有其他官能团的分析物，但此类材料表现出独特的电氧化成脂肪醇的电催化特性。本文报告了对双原子金纳米复合物对具有其他功能基团的分析物的双原子响应而获得的循环伏安模式的研究，用于传感器应用。主成分分析表明，在正丙醇，异丙醇和甲酸乙酯/乙醇基团之间存在分离。甲酸乙酯的间接感测通过在碱性介质中水解后产物的电氧化来证明。气相研究了甲酸乙酯的伏安图。
