Airtight in Situ Thin-Layer Reflection-Absorption FT-IR Microspectroelectrochemical Cell for the Study of Nonaqueous Systems

摘要

An airtight thin-layer reflection Fl-IR microspectroelectrochemical cell suitable for the study of both aqueous and nonaqueous electrochemical systems is described. Due to its design, the cell can be easily assembled using disk microelectrodes. This variable-thickness cell can be used for the voltammetric study of both aqueous and nonaqueous systems under semi-infinite diffusion and thin-layer conditions. Dichloromethane solutions of ferrocene were used to test the in situ FI-IR microspectroelectrochemical performance of tile cell. The cyclic voltammetric behavior of an oxygen- and water-free CH↓(2)-Cl↓(2) solution of Ru↓(3) (CO)↓(12), under semi-infinite diffusion conditions, provides evidence of the airtightness of this cell.
