直立式光透金网电极薄层红外光谱电化学池的新设计

A Novel Design of Light-Transparent Gold-Minigrid Thin-Layer FTIR Spectroelectrochemical Cell with Vertical Configuration

本文报告一种新式的光透式金网电极薄层红外光谱电化学池设计。该设计使用聚四氟乙烯池内盐桥/边际限制器,连接直立式玻璃池体与氯化钠红外薄层池,设置薄层池内的电位参比点,既便于监控操作,又能得到良好的光谱电化学响应。以二茂铁在二氯甲烷中的行为进行了表征。

A Teflon bridge/edge-eliminator is designed to connect a glass container and a light-transparent gold-minigrid NaCl thin-layer cell to form a vertically configured in-situ FTIR spectroelectrochemical cell. The bridge/edge-eliminator sets an internal reference point for accurate potential control. The size of the thin-layer chamber is 5×5×0.11mm. A 1900 Ω formal resistance of the thin-layer cell was measured in CH_2Cl_2/0.1 M TBAP solution. Well defined thin-layer cyclic voltammograms and IR specctral changes for ferrocene oxidation were obtained.
