Acidic chloride electrolyte mediates the high conversion ratio of CO2-to-C2H4 and direct production of Cl2

Abstract

We design an efficient catalytic system for C2 and Cl2 formation by coupling CO2R and CER in an acidic environment. It can support C2H4 and Cl2 with 63% and 89% FEs at 700 mA cm−2. This provides a valuable reference for the development of the CO2RR.
