Controlled potential electrolysis and CoPc2 film characterization. (a) Current density and selectivity for CO production as a function of the potential and (b) bulk electrolysis at a fixed potential (E  =  −0.72 V vs. RHE) for CoPc2@carbon black deposited onto a carbon paper as cathodic material, in 1 M KOH. c Co K-edge XANES profiles of CoPc2 (black dots) and CoPc2@carbon black before (blue) and after electrolysis (E  =  −0.72 V vs. RHE) (red) in 1 M KOH solution.
