Electrocatalyst for oxygen reduction reaction (ORR) are essential for metal-air batteries. Herein, we design a self-catalyzed growth strategy for in-situ encapsulation of Co nanoparticles with N-doped carbon nanotubes (NCNT) on carbon aerogel (CA) (Co/NCNT/CA-1000). Using the zeolite imidazole framework (ZIF-67) as the cobalt source can catalyze the graphitization of melamine and facilitate the growth of NCNTs on the CA. Thanks to its unique structure, the Co/NCNT/CA-1000 exhibits favourable ORR properties (E 1/2 = 0.80 V). This work offers an effective method for preparing high-active Co-based electrocatalysts and provides a foundation for the future development of electrochemical energy applications.
