FRR mechanisms on ZnPc/CNT. (a) EPR spectrum of the ZnPc/CNT collected after discharging at −0.6 VRHE in a 0.1 M K2CO3/KHCO3 electrolyte (pH = 10.2) for 10 min. (b) Tafel plots. (c) KIE test results. (d) Reaction order of HF formation with respect to cfurfural at different pH. (e) EPR spectrum of the catalyst collected after discharging at −0.6 VRHE in a 0.1 M KOH electrolyte (pH = 12.6) for 10 min. (f) N 1s XPS spectra of the catalyst collected before and after testing in the 0.1 M KOH electrolyte.
