Abstract

Abstract : A Pt‐free nanoreactor, consisting of N‐doped hollow carbon nanocapsules with encapsulated Ni nanoparticles, is developed for high‐performance oxygen reduction reaction (ORR) catalyst. The nanoreactor effect improves its catalytic activity for ORR mainly in a 4e − pathway. The presence of Ni nanoparticles within the nanoreactor significantly enhances the stability with a current retention of 90% after 40 h.
