(86g) New Catalytical System in Ionic Liquid for Small Molecule Conversion

Ionic liquids (ILs) have gained practical and fundamental interests as replacements of conventional electrolytes in modern electrochemical devices (e.g., advanced batteries, fuel cells, super-capacitors, sensors, and electrochromic displays). All electrochemical applications require fundamental understanding of the interface reactions, interface structure, and properties which can be obtained through in situ characterization of the dynamic interface processes. In this work, we discuss new catalytical system detrived from ionic liquid and IL–electrode interface for methane, CO, methanol and et.al conversion, which were conducted in our lab. The related in situ characterization techniques including electrochemical impedance spectroscopy (EIS), electrochemical quartz crystal microbalance (EQCM), and in situ infrared spectroscopy (IR) for studying IL–electrode interface will be presented. This task-specific ILs and their surface immobilization on solid supports as a replacement of conventional recognition elements and electrolytic media could be widely applied in green energy and enviromental monitoring.
