title: Hollow nitrogen-doped carbon spheres as efficient and durable electrocatalysts for oxygen reduction.
abstract: Hollow nitrogen-doped carbon spheres (HNCSs) were prepared by a facile method as non-precious catalysts for the oxygen reduction reaction (ORR). The HNCS catalysts exhibited ORR activity comparable with a commercial Pt/C catalyst and superior stability in alkaline electrolyte medium.
