Graphite-like carbon nitride(g-C3N4) was synthesized in large quantities at 300 C under nitrogen by a solidstate reaction route.Furthermore,Al3+ and Mg2+ intercalation of g-C3N4 was performed by an electrochemical method.The starting C3N4 materials and intercalation compounds were characterized by X-ray powder diffraction,Fourier transform infrared spectra,thermogravimetry,transmission electron microscopy,and X-ray photoelectron spectroscopy.The possible structure model of intercalation compounds was proposed.The cation-π interactions and electrostatic interactions were used to explain the changes of microstructure and chemical bonds before and after intercalation.
