A Super Thin Layer Optically Transparent Electrode for in-situ Infrared Spectroelectrochemistry

采用真空镀膜技术制得了超薄型红外光透电极,设计了适用于水溶液体系和多种固体电极体系的红外光透薄层电解池,通过亚铁氰化钾水溶液/金电极体系和亚琉酰氯/碳电极体系的现场红外光谱电化学测试证明:该电解池具有结构简单、光谱响应灵敏、适用范围较宽等优点。

A new optically transparent thin layer electrode (OTTLE) was developed for in-situ IR spectroelectrochemistry of aqueous system. The optically transparent electrode (OTE) was fabricated by vacuum depositing technique. The in-situ FTIR spectroelectrochemistry was carried out for the redox reactions of ferri/ferrocyanide (on An electrode) and thionyl chloride (on carbon electrode). By comparion with conventional OTTLE. this novel design of IR OTTLE is shown to have sufficient sensitivity and experimental simplicity for obtaining IR spectra of the species generated during electrochemical oxidation-reduction in aqueous solutions.
