Li et al. [213] designed and synthesized an efficient and stable non-precious metal
ORR catalyst (Fe-SPc) based on iron phtalocyanine. This Fe-SPc is prepared by a
non-pyrolytic method so that its surface properties derived from the structure and
material can be appropriately adjusted. Fe-SPc has an initial ORR activity equivalent
to that of commercial Fe-Pc, but after 10 cycles of scanning, the current density of
Fe-SPc is 4.6 times that of Fe-Pc, and after 100 cycles of scanning, the current
