摘要
The bulk g - C3N4 had been synthesized by a facile chemical pyrolysis method, which is based on the self-condensation of cyanamide, dicyandiamide, and melamine to generate g - C3N4. These materials were also characterized by XRD, UV - vis spectra and FT - IR, and elemental analysis. Photocatalytic activity of g - C3N4 was evaluated by the photodegradation of methylene blue (MB). The experiments compared the photocatalytic activity of g - C3N4, which was synthesized from the varying precursors at 520 degrees C. The results indicated that the g - C3N4 obtained from dicyandiamide exhibited high photodegradation activity. Based on our comparison experiments, a possible mechanism for g - C3N4 photocatalysis system was proposed.
