摘　　要：以碳纳米管(CNT)为原料,通过负载维生素B12,简单热解得到了一种氮掺杂碳纳米管(N/CNT)负载低含量Co_(3)O_(4)纳米颗粒的氧还原电催化剂(Co_(3)O_(4)@N/CNT)。得益于均匀分散的Co_(3)O_(4)纳米颗粒以及氮掺杂,Co_(3)O_(4)@N/CNT表现出了优异的氧还原催化性能,其半波电位达到了0.844 V(vs RHE),超越了商业Pt/C(0.820 V(vs RHE))。与Pt/C相比,基于Co_(3)O_(4)@N/CNT组装的锌-空气电池表现出了更优的放电性能和循环稳定性。Carbon nanotube(CNT)was used as raw materials,loaded with vitamin B12,and then subjected to simple pyrolysis to obtain a nitrogen doped carbon nanotube(N/CNT)and loaded with low content Co_(3)O_(4) nanoparticles(Co_(3)O_(4)@N/CNT)as an oxygen reduction reaction electrocatalyst.Due to the uniformly dispersed Co_(3)O_(4) nanoparticles and N-doped effect,Co_(3)O_(4)@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 Co_(3)O_(4)@N/CNT exhibited better discharge performance and cycle stability.
