Abstract
The present invention relates to a synthetic method of graphitic carbon nitride material. The method involves a homogenous mixing of carbon nitride precursor and ammonium salt, and calcining the mixture to obtain a porous graphitic carbon nitride material. Wherein, the ammonium salt is any one or a combination of at least two which could release gaseous NH3 during thermolysis. The present invention uses thermolabile ammonium salt as a pore former; the thermolysis of ammonium salt could release soft gas bubbles during the calcination; the later burst of bubbles leads to the formation of nanoporous structure. The proposed method is template-free and environmentally-friendly, and the resultant material exhibits high photocatalytic activity in the field of gas and water decontamination.
