▎ 摘  要

NOVELTY - Method for preparing graphene-like carbon nitride involves taking urea as a raw material, fully dissolving urea in distilled water, placing the aqueous urea solution in a crucible with a cover, calcining in an electric furnace, naturally cooling, crushing and sieving to obtain porous wide-band gap graphene-like carbon nitride material. USE - Method is useful for preparing graphene-like carbon nitride, which is useful for degrading organic dye pollutant in water, where the organic dye is methylene blue and rhodamine B. ADVANTAGE - The method ensures simple, environmentally-friendly and economical preparation of the graphene-like carbon nitride with adjustable wide-band gap of 2.81-2.87 eV, high yield and excellent stability and organic dye degradation rate of 75-85%.
