摘　　要：报道一种新型的适用于水和非水溶剂的反射式现场显微红外光谱电化学池。该池利用毛细管效应来克服显微池中溶剂挥发和除氧的困难，保证电解薄层能长时间保持浸润和良好的工作状态。安装了 ５０ μｍ直径的铂微盘工作电极，分别在水溶液和二氯甲烷溶液中，用Ｆｅ（ＣＮ）６４－／３－和二茂铁体系进行了表征。This paper reports a newly designed reflectance FTIR microscopic electro chemical cell. This cell is suitable for investigations in aqueous and non-aqueous media. The cell was made from Teflon. A capillary tunnel in-between the thin-layer electrolysis chamber and the bulk solution chamber was used for maintaining the thin layer section in good working condition. Other advantages of the cell are: (1)the bulk solution can be degassed using N2 bubbling, (2)the iR drop is reduced and accurate potential control of the thin layer electrolysis can be achieved, (3)the cell is simple in construction and convenient for use. Cyclic voltammetric and in-situ microscopic FTIR spectroscopic performance has been characterized at a 50 μm platinum disk working electrode using Fe (CN )64-/Fe (CN )63- in aqueous solution and Fc/Fc+ in C2H4Cl2 solution. Excellent electrochemical behavior and IR spectroscopic responses were obtained in both of these systems.
