▎ 摘 要
NOVELTY - Preparing carbon nitride-graphene complex, comprises (i) preparing graphite oxide dispersion solution, which peels off graphite oxide under solvent, and (ii) adding cyanamide to the dispersion solution and refluxing at 100-150 degrees C. USE - The carbon nitride-graphene complex is useful as catalyst in oxygen reduction reaction for fuel cell (claimed). ADVANTAGE - The method is carried out at low temperature and ensures large quantity of carbon nitride-graphite complexes.
