▎ 摘　　要

NOVELTY - The preparation method of graphene-like carbon nitride involves using nitrogen-rich organic material as raw material, adding a microwave absorber, mixing, and adding into a ceramic crucible, placing the crucible in an industrial high-energy microwave resonator cavity, vacuumizing, high-energy microwave irradiating, and heating. USE - Preparation of graphene-like carbon nitride used in degradation of organic matter, photolysis of water, catalyst carrier, and biomedical sensor. ADVANTAGE - The method enables the preparation of graphene-like carbon nitride with high specific surface area, yield, and purity.
