摘要：

Carbon nanotube (CNT) was used as raw materials, loaded with vitamin B-12, and then subjected to simple pyrolysis to obtain a nitrogen doped carbon nanotube (N/CNT) and loaded with low content Co3O4 nanoparticles (Co3O4@N/CNT) as an oxygen reduction reaction electrocatalyst. Due to the uniformly dispersed Co3O4 nanoparticles and N-doped effect, Co3O4@N/CNT exhibited excellent oxygen reduction reaction catalytic performance, with a half wave potential of 0.844 V (vs RHE), surpassing the performance of commercial Pt/C (0.820 V vs RHE). Compared to Pt/C, the zinc-air battery based on Co3O4@N/CNT exhibited better discharge performance and cycle stability.
