用于现场FTIR及UV/Vis光谱电化学的高质量简单结构的光透薄层电化学池

摘要

设计制作了一种应用于紫外可见、红外电谱电化学的新型光透薄层电化学池(OTTLE),并以铁氰化钾水溶液、二茂铁乙腈溶液体系进行了表征.池腔几何结构的合理设计使电位降和边缘效应降至最低.该池有良好的伏安响应特性并可用它得到高质量的UV/Vis和IR光谱.由于简单的结构及低廉的造价使适用于光谱电化学研究的电化学池变得更容易得到.%A novel optically transparent thin layer electrochemical (OTTLE) cell for ultraviolet, visible and infrared spectroelectrochemistry (SEC) was designed and characterized using ferricyanide in aqueous solutions and ferrocene in MeCN as test systems. The geometry of the cell cavity was carefully designed to minimize the ohmic potential drop and edge effect. Good voltammetric characterization and high quality spectra were obtained with the cell. The simple construction and inexpensive fabrication made it easier to obtain a cell suitable for SEC studies.
