Electrochemical CO2RR performance on (Cl, N)-Mn/G catalyst and control samples of N-Mn/G, MnO/G and carbon paper. a LSV curves of different catalysts (in a CO2-saturated 0.5 M KHCO3 solution, scanning rate: 10 mV s−1). b FECO at various applied potentials. c Potential-dependent CO partial current density. d TOF of (Cl, N)-Mn/G catalyst compared with those of other CO2 to CO reduction catalysts in the Supplementary Table 57,8,9,10,11,12,13,29,31-41. e Charging current density differences plotted against scan rates. f EIS spectra. The inset shows the enlarged Nyquist plots for high frequency region. All data in b are presented as mean ± s.d.
