Figure 6. (A) Schematic illustration of a general synthetic approach to CoM-P NSs for high-efficiency OER derived from bimetallic MOFNs. (B) (1) Crystal structure, (2) SEM image of CoNi(20:1)-ZIF precursor and (3) TEM. (C) (1) Polarization curves of CoP-NS and CoM(20:(1)-P-NS (M = Ni, Mn, Cu or Zn) and of (2) CoNi(20:1)-P-NS on GCE or Ni foam (NF), CoNi(20:1)-ZIF-P. Reproduced with permission.
