Nanoarchitectures provide a new impulse to develop highly efficient electrocatalysts for the oxygen reduction reaction (ORR). Nitrogen‐doped 1D or 2D carbon‐based catalysts exhibit highly catalytic performances, owing to their distinctive features. Of great interest is the fabrication of novel nanostructures combining the advantages of 1D and 2D materials. To achieve this challenge, homogenous core–shell nitrogen‐doped carbon nanotubes were successfully prepared by using a simple one‐pot method. The unique structure possesses the features of common carbon nanotubes (core) and standing graphite (shell). The novel structure with a synergistic effect of 1D and 2D materials contributes to enhanced ORR activity. Moreover, the core–shell catalysts exhibit long‐term stability and high tolerance to methanol‐poisoning effects, which are shortfalls for commercial Pt/C electrocatalysts.
