Abstract

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 ([email protected]–N–C). Owing to the 1D mesoporous architecture with abundant active sites, [email protected]–N–C hybrid showed superior ORR activity, high selectivity, and long-term durability. Moreover, as cathode catalyst for primary Zn–air battery, [email protected]–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. Graphical AbstractA 1D hybrid electrocatalyst composed of Co/CoOx nanoparticles embedded in N-doped mesoporous carbon layer coated on carbon nanotubes ([email protected]–N–C) was prepared for efficient ORR.
