Insights on Dual-Functional Ionic Liquid Interfacial Layer for Efficient CO2 Electroreduction to C2+ Products in Acid.
Electrocatalytic CO2 reduction reaction (CO2RR) in acidic electrolyte is hindered by severe hydrogen evolution reaction (HER) and inefficient C-C coupling, leading to poor selectivity toward multicarbon (C2+) products. Here, we construct a dual-functional interfacial layer by modifying a CuO catalyst with the ionic liq...
