AbstractThe C-containing iron nitride electrocatalyst is fabricated by chelating N-containing species and Fe2+ with a carbon support under heat treatment in an NH3 atmosphere, which induces the oxygen reduction reaction activity. This is the first demonstration of forming FexC species on iron nitride materials. The correlation between the electrochemical properties and structures are aided to elucidate their features under investigation by using X-ray absorption spectroscopy. A rotating ring disk electrode test is conducted in sulfuric acid solution and the results reveal the low H2O2 yield and approximately 4e- transfer process of the carbon-containing FeN/C electrocatalyst. © 2011 Elsevier Ltd.
