Abstract

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