NOVELTY - Control synthesis of pyramid array structure graphene-like carbon nitride nanosheets comprises using melamine as raw material and carbon fiber as microwave absorber, putting into a crucible, placing in microwave resonant cavity, vacuumizing, microwave irradiation heating, and adjusting duty cycle and pulse period. USE - Method for control synthesizing pyramid array structure graphene-like carbon nitride nanosheets used for photocatalytically degrading organic matter, photolysis hydrogen production, catalyst carrier, and sensor.
