Abstract
Abstract Multi‐heteroatom‐doped metal‐free carbons with well‐tailored electronic structures are regarded as promising oxygen reduction reaction (ORR) catalysts. However, their active sites are often hindered by the carbon matrix, resulting in reduced catalytic activity. Herein, nitrogen, phosphorus, and sulfur tri‐doped hollow hierarchical porous carbon nanofibers (NPS‐HPCNFs) with interpenetrated pores are synthesized using a facile coaxial electrospinning method. The distinctive steric confinement induced by the interpenetrated pores created a positive microenvironment for the ORR. As a result, the resultant NPS‐HPCNF catalyst exhibits a half‐wave potential ( E 1/2 ) of 0.86 V (vs. RHE) and superb long‐term…
