NOVELTY - An iron nitride/nitrogen-doped graphene airgel contains 3-dimensional iron nitride nanoparticle load and nitrogen-doped graphene airgel. USE - Iron nitride/nitrogen-doped graphene airgel for oxidation-reduction catalyst (claimed). ADVANTAGE - The airgel has no noble metal content, low cost, excellent stability and anti-oxidizing methanol property, and catalytic activity exceeding platinum/carbon (Pt/C) catalyst at low amount. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of iron nitride/nitrogen-doped graphene airgel which involves dispersing graphite oxide and organic iron compound in water to obtain oxidized graphite and organic iron compound mixed liquid in which mass ratio graphite oxide:organic iron oxide is 1:0.5-4, adjusting graphite oxide concentration in mixed liquid to 1.5-4 mg/ml, performing hydrothermal reaction at 180-220 degrees C, heat-preserving for 10-14 hours to obtain hydrothermal reaction product, heating to 600-800 degrees C in ammonia gas, and insulating for 1-4 hours. DESCRIPTION OF DRAWING(S) - The drawing shows a high-resolution transmission electron microscope image of iron nitride/nitrogen-doped graphene airgel. (Drawing includes non-English language text).
