a Schematic illustrating the surface modulation of 4-nitrogen surrounded single metal sites on a nitrogen-doped carbon layer ((HMO represents hydrotreated MoO3, MPor represents metal porphyrin, exemplified across the sM(N4)@NC family, M = Ni, Cu, Co and Ni/Cu); (b) FTIR spectra of HMO@PPy and sNi(N4)@PPy (T% represents a relative value); (c, d) Aberration-corrected high-angle annular dark-field scanning TEM images of sNi(N4)@NC-3 and (e) corresponding EDX mapping of C, N, Ni.
