Figure 1. Molecular construction and structural characterizations. (a) Schematic diagram of CoPc-PM@CNT, CoPc-NT@CNT, and CoPc-PT@ CNT. (b) TEM and (c) HRTEM images of CoPc-PM@CNT. (d) Double aberration-corrected HAADF-STEM image of CoPc-PM@GP (inset: atomic model of CoPc; hydrogen atoms have been hidden for clarity). (e) Elemental mappings of CoPc-PM@CNT. (f) Co K-edge XANES profiles of Co foil, CoO, Co2O3, and the catalysts. (g) FT-EXAFS of the Co foil, CoO, Co2O3, and the catalysts. (h) WT-EXAFS plots of the CoPc-NH2@ CNT, CoPc-PM@CNT, CoPc-NT@CNT, and CoPc-PT@CNT, respectively.
