Original Paper


An attapulgite/TiO2/graphene composite (ATP/TiO2/RGO) was prepared and characterized by X-ray powder diffraction, Fourier transform infrared spectra, Raman spectra, transmission electron microscope, scanning electron microscope, ultraviolet–visible diffuse reflectance spectra, photoluminescence spectra and X-ray photoelectron spectroscopy. Results showed that TiO2 nanoparticles were loaded on the surface of ATP uniformly and the introduction of RGO successfully expanded the light response range of TiO2. The photocatalytic performance of the composite toward the degradation of chlorotetracycline was then evaluated, and a plausible mechanism was proposed. It was found that the ternary composites exhibited excellent photoactivity when compared with the ATP/TiO2 binary material and pure TiO2, indicating that the synergistic effect of TiO2, ATP and RGO greatly enhanced the photocatalytic activity of the present ternary composite.
