Abstract: Using urea as the starting material, we prepared the lamellar structure of graphite carbon nitride (g-C3N4) by hightemperature pyrolysis method. The structures and morphologies of the samples were characterized by X-ray diffraction (XRD), X photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). Rhodamine was used to test the photocatalytic and cyclic catalytic performances of the sample. The results show that the g-C3N4 nanosheets have high photocatalytic activity and cyclic catalytic performance.

Key words: photocatalytic degradation, cyclic catalysis, nanosheets, graphite carbon nitride
