TiO2/g-C3N4 nanosheets hybrid photocatalyst with enhanced photocatalytic activity under visible light irradiation

摘要: The nanosheets TiO2/g-C3N4 hybrid material with efficient visible-light photocatalytic activity was prepared by a facile solvothermal method. as-prepared composite thoroughly characterized X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, N2 adsorption–desorption analysis, UV–Vis diffuse reflectance and photoelectron spectroscopy. As evaluated the degradation of methylene blue under visible light irradiation, composites exhibit much higher than pristine g-C3N4 TiO2, respectively. significant enhancement in photodegradation over photocatalyst can be ascribed to combined effects nanosheet structure subsequent separation photogenerated charge carriers. A tentative mechanism for process proposed.
