Figure 2. (A) HRTEM image of Fe30Co30Ni30-PNC; (B) HAADF-STEM and corresponding elemental mapping images show the distribution of (C) P, (D) Fe, (E) Co, and (F) Ni, elements in Fe30Co30Ni30-PNC; (G) EELS and (H) aberration-corrected HAADF-STEM image of Fe30Co30Ni30-PNC. HRTEM: High-resolution transmission electron microscope; PNC: phosphorus and nitrogen doped carbon; HAADF-STEM: high-angle annular dark-field scanning transmission electron microscopy; EELS: electron energy loss spectroscopy.
