Construction of Sn3O4/g-C3N4 composite with enhanced photocatalytic activities under visible light irradiation

The Sn3O4/g-C3N4 composites were produced by an annealing mixture of g-C3N4 and Sn3O4, which were prepared by calcining urea and hydrothermally treating of SnCl2 solution, respectively. Chacterization of the samples was investigated by powder X-ray diffraction (XRD), Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), Photoluminescence (PL) and UV-Vis spectra.
