发明名称 method of preparing carbon nitride-graphene composites and the carbon nitride-graphene composites prepared by the same method
摘要 The present invention relates to a method of preparing a carbon nitride (C3N4)-graphene composite and the carbon nitride (C3N4)-graphene composite prepared thereby. The present invention provides the method of preparing the carbon nitride-graphene composite comprising: a step (step 1) of manufacturing a graphene oxide dispersion solution by peeling off a graphite oxide in a solvent; and a step (step 2) of adding cyanamide in the dispersion solution and refluxing them at a temperature of 100-150°C. The method of preparing the carbon nitride according to the present invention effectively reduces a functional group containing oxygen bonded to the surface of the graphene oxide, forms a carbon nitride structure at low temperatures as compared to the existing process for preparing the carbon nitride and has advantages such as producing the carbon nitride (C3N4)-graphene composite in large quantities.
