Pyrolysis Synthesized g-C3N4 for Photocatalytic Degradation of Methylene Blue

الملخص EN

Graphitic carbon nitride (g-C3N4) was synthesized at 520°C by the pyrolysis of cyanamide, dicyandiamide, and melamine.

The samples were characterized by X–ray diffraction (XRD), UV-visible diffuse reflectance spectra, Fourier transform infrared spectroscopy (FT-IR), and elemental analyzer.

The photocatalytic activity of g-C3N4 was evaluated by the photodegrading experiments of methylene blue (MB).

The results indicated that g-C3N4.

A photocatalytic mechanism presumed the MB photodegradation over the C3N4 photocatalyst is attributed to photogenerated electron impelled multistep reduction of O2.
