Abstract：The synthesis of graphene-like carbon nitride has been a new research hotspot in the field of two-dimensional functional materials due to its similar structural characteristics to graphene and outstanding properties covering photocatalysis and lubrication and so on. Herein, the research progress of the microwave irradiation synthesis of graphene-like carbon nitride was discussed. Based on the comparison to the traditional preparation approaches including high-temperature oxidation corrosion, liquid phase ultrasonic exfoliation and thermal polymerization, etc., the advantages of microwave irradiation synthesis were analyzed. At the same time, one can find that by means of using high-energy microwave instrument and microwave absorbents covering graphite powders and short carbon fibers that possess excellent microwave energy absorption ability, the transferring and absorption efficient of energy as well as the non-steady degree of the synthesis reactions occurred in the microwave electromagnetic field can be enhanced, is consequently beneficial to the achievement of novel products with special morphology and structure.
