Ionic liquids enhance the electrochemical CO2 reduction catalyzed by MoO2†
Several imidazolium-based ionic liquids significantly enhance the activity of MoO2 for electrochemical reduction of CO2. The overpotential of CO2 reduction is as low as 40 mV. The ionic liquids act as both electrolytes and co-catalysts, which not only leads to lower overpotentials, but also alters the product selectivity.
