摘要：

One-dimension (1D) heteroatom-doped mesoporous carbon is a promising alternative catalyst for oxygen reduction reaction (ORR). This work reported a hybrid ORR electrocatalyst composed of Co/CoOx nanoparticles embedded in N-doped mesoporous carbon layer coated on carbon nanotubes (CNTs@Co-N-C). Owing to the 1D mesoporous architecture with abundant active sites, CNTs@Co-N-C hybrid showed superior ORR activity, high selectivity, and long-term durability. Moreover, as cathode catalyst for primary Zn-air battery, CNTs@Co-N-C also showed excellent performance comparable to Pt/C. Thus, this study can offer a good idea for preparing noble-metal-free electrocatalysts for energy applications.
