To improve the oxygen reduction reaction's reaction, proper regulation of metal-nitrogen carbon materials derived from zeolitic imidazolate frameworks is critical. With the porous carbon nanocages arranged one by one in the highly conductive carbon nanofibers, we have produced a bead-like cobalt-nitrogen co-doped carbon nanocage/carbon nanofiber composite electrocatalyst with the porous carbon nanocages arranged one by one in the highly conductive carbon nanofiber composite electrocatalyst manufactured herein. The Co_NP-N-C_2 active sites on Co-N-C/CNF make the most important contribution to the improvement of ORR properties, according to the Density functional theory results. In addition, the zinc-air battery based on the Co-N-C/CNF catalyst also exhibits outstanding discharge results.
