Graphitic carbon nitride (g-C3N4) nanosheet was synthesized by a facile fabrication method. Melamine was treated by a thermal polycondensation process. Pure g-C3N4 was treated by acid etching, heat etching and coupling with NH4Cl. The crystalline structure, morphology, specific surface area, band structure and visible absorption of the material were evaluated by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy analysis, X-ray photoelectron spectroscopy, Raman spectroscopy, specific surface area (BET analysis), ultraviolet visible diffuse reflection spectroscopy and Mott-Schottky curve analysis, respectively. The photocatalytic activity was estimated by the degradation of Rhodamine and tetracycline hydrochloride solution under visible light irradiation. The results show that a clear, ordered, 2D nanosheet g-C3N4 structure with a layer thickness of 47 nm is formed, and the maximum specific surface area is a maximum (22 m2/g) when the mole ratio of melamine to NH4Cl is 5∶4. The photocatalytic performance of bulk g-C3N4 is enhanced after treatment. The photocatalytic degradation rate of the sample treated with melamine and NH4Cl at a ratio of 5∶4 is 3.4 times greater than that of untreated g-C3N4. The sample degrades 83.2% tetracycline hydrochloride solution for 4 h.
