Cobalt-based subsurface dopants induce a shift in the rate-determining step of electrochemical CO2 reduction on copper to the chemical step: OCCO* + H* → OCCHO* + *. Electrochemical production of ethylene over the optimized catalyst is achieved at low voltage and high current in a membrane electrode assembly system.
