Pyrazolium Ionic Liquid Co-catalysts for the Electroreduction of CO2

Paul Joseph Dyson, Dmitry Vasilyev, Erfan Shirzadi

Pyrazolium ionic liquids (Pz ILs) were employed as co-catalysts for electrochemical conversion of CO2 to CO on a silver disk electrode, leading to a significant decrease in the onset potential for the reduction (ca. 500 mV). The electrochemical conversion ...
