摘要	In this study, we developed a hydrothermal method to prepare hybrid TiO2@glucose carbon spheres (TiO2@GCs) with controllable structures. The prepared products were characterized using scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). The results showed that the morphology of the as-synthesized TiO2@GCs hybrid composites could be facilely controlled by varying the amount of titanium tetrachloride (TiCl4). X-ray diffraction (XRD) was used to determine the crystallite size, composition, and phase purity. Fourier transformed infrared spectroscopy (FT-IR), UV-vis diffuse reflectance spectra (UV-vis DRS) and BET specific surface area measurements (BET) were conducted to evaluate the surface functional compositions, light response ability and pore structure, respectively. Based on the observations made with different phase structures before and after hydrothermal treatment of the TiO2@GCs precursor, a reasonable mechanism for the formation of TiO2@GCs hybrid microspheres was proposed. Moreover, the as-synthesized TiO2@GCs hybrids exhibited improved dye-adsorption capacity and enhanced photocatalytic ability, which could be assigned to the synergistic effect of the photocatalytic function of TiO2 and the adsorption function of the carbon spheres. This novel synthetic approach provides a simple and flexible way to prepare TiO2@GCs hybrid composites with controllable structures, and the TiO2@GCs photocatalyst is expected to deliver a new engineering solution for the industrial dye-containing wastewater treatment process.; In this study, we developed a hydrothermal method to prepare hybrid TiO2@glucose carbon spheres (TiO2@GCs) with controllable structures.
