Polymeric ionic liquid promotes acidic electrocatalytic CO₂ conversion to multicarbon products with ampere level current on Cu.

ABSTRACT: The acidic electroreduction of CO₂ into multicarbon (C₂₊) products is much attractive for the improved carbon utilization than alkaline or neutral electroreduction. How to improve the efficiency of C₂₊ products generation by acidic electroreduction of CO₂, is important, especially at high current density and in electrolyte with low K⁺ concentration. Herein, we propose a strategy of capping Cu surface with a polymeric ionic liquid (PIL) adlayer for boosting the acidic electrocatalytic CO₂ conversion to C₂₊ products at high current densities (ampere-level) and low K⁺ concentration. In the electrolyte with a relatively low K⁺ concentration (1.0 M), the Faradaic efficiency (FE) for C₂₊
