Potentiostat for Characterizing Microstructures at Ionic Liquid/Electrode Interfaces

This report details the procurement and integration of a multichannel potentiostat BioLogic VMP 16 Channel Potentiostat into ourelectrochemistry program. In short, the instrument has been of great service to characterize ionic liquid-based IL-based electrolyte systemsvia simultaneous electrochemical and spectroscopic studies. These data are pertinent to understanding the microscopic molecular and ionicdynamics of electrolyteelectrode interfaces. This information that is a prerequisite to engineered progress of many important energyconversion processes and devices e.g., supercapacitors. The potentiostat has been synchronized with an infrared spectrometer to performsurface enhanced infrared absorption SEIRA spectroscopy with electrochemical control. The multichannel instrument has also beenutilized to study mass transport in mesoporous films. Sample data from these ongoing efforts are demonstrated later in this report.
