a Comparison of the FEs of various products at 300 mA cm−2 on a poly-Cu GDE in 1 M KOH with and without 13 mM EDTMPA additive. b Stability test over 6 h of a poly-Cu GDE at 300 mA cm−2 in 1 M KOH with 13 mM EDTMPA additive. c Comparison of our work with previous studies on the electrocatalytic CO2-to-CH4 reaction in a flow cell with partial current densities over 100 mA cm−2 (Refs. 46,59,60,61,62,63,64,65,66).
