Porous structure, nitrogen defects and oxygen dopants are simultaneously introduced into the framework of graphitic carbon nitride (g-C3N4) by a simple co-pyrolysis of dicyandiamide and ammonium persulphate ((NH4)2S2O8). The (NH4)2S2O8 plays multi-function roles in the co-pyrolysis process. It not o...
