英文摘要	Nanoporous graphitic carbon nitride was prepared through direct heat treatment of guanidinium cyanurate at 550-600 degrees C in an air atmosphere. The BET surface area of the resulting materials can reach 200 m(2) g(-1). High porosity was developed through a heat-driven stacking of g-C3N4 nanosheets. The mechanism was revealed in detail through TEM and N-2 adsorption measurements. Large-size g-C3N4 nanosheets are formed at 550 degrees C and stacked in a state similar to randomly creased paper slips. Further increase of treatment temperature to 600 degrees C results in curling and fragmentation of g-C3N4 nanosheets, which build up a highly porous matrix. Nanoporous graphitic carbon nitride with higher surface area exhibits better optical properties and has enhanced photocatalytic activity. The nanoporous g-C3N4 shows high photocatalytic activity for the decomposition of rhodamine (RhB) in an aqueous solution.
