Abstract:

A simple and template-free synthesis method was developed to fabricate porous graphitic carbon nitride (g-C3N4) through a hydrothermal process in the presence of ammonium hydroxide. The effect of ammonium hydroxide on the structure of porous g-C3N4 was characterized in details by XRD, FT-IR, SEM and TEM. The photocatalytic activity of porous g-C3N4 was evaluated by the degradation of methylene blue (MB) under visible light irradiation. The results show that as-prepared porous g-C3N4 exhibits a porous nanostructure composed of 2D nanosheets and interconnected pores. The photocatalytic activity of porous g-C3N4 is enhanced, owing to the synergistic effect of more reaction sites and good separation efficiency of photo-generated carriers.
