| 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Co3O4纳米颗粒的氧还原电催化剂(Co3O4@N/CNT)。得益于均匀分散的Co3O4纳米颗粒以及氮掺杂,Co3O4@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Co3O4@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。

| Abstract: | 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 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. |
