a SEM image of Co-POP-C. b TEM image of Co-POP-C. c HRTEM image of Co-POP-C. Images in (a)–(c) are representative of 3 independent measurements with similar results. d Normalized Co K-edge XANES spectra of Co-POP-C and reference samples. e k2-weighted Fourier-transform (FT) Co K-edge EXAFS spectra of Co-POP-C and reference samples. In (d) and (e), colors denote: Co foil (yellow), CoO (pink), CoPc (green) and Co-POP-C (blue). f Wavelet transforms for the k3-weighted Co K-edge EXAFS signals of Co-POP-C and reference samples. Source data are provided as a Source Data file.
