Nitrogen doped sublimed carbon as non-noble metal catalyst for oxygen reduction reaction

• A sublimed carbon material is prepared by a simple solid-state pyrolysis method.
• The carbon material is doped with nitrogen with different nitrogen sources.
• The nitrogen doped sublimed carbon show good performance as catalyst for the oxygen reduction reaction.

A sublimed carbon has been synthesized by a simple solid-state pyrolysis method and the carbon works as non-noble metal oxygen reduction catalyst after doping with nitrogen. The content of nitrogen introduced by doping is found to be a factor influencing the electrocatalytic activity. The nitrogen doped carbon can find potential applications in fuel cells and other devices where oxygen reduction reaction works as cathode reaction.
