Photocatalytic nanocomposites of titanium dioxide (TiO2) were prepared by hydrothermal method. Reduced graphene oxide (RGO) was applied to prepare various TiO2 composites of doped nanoparticles by using NH4Cl and FeCl3 as sources. The structure and morphology of these composites showed that TiO2 was loaded on surface of RGO. Meanwhile, the agglomeration of TiO2 decreased and the dispersion became uniform for doped materials. Under ultraviolet (UV) light irradiation, the photocatalytic degradation of volatile organic compounds (VOC) by RGO/TiO2 composites with codoping of N and Fe reached to 90.5%. The photocatalytic degradation was higher than RGO/TiO2 composites and pure TiO2 by 1.8 and 5.9 times, respectively. The role of co-doping composites may have a possible mechanism for toluene under UV light irradiation. The enhanced photocatalytic properties were attributed to N and Fe doping which generated intermediate energy level, extended absorption and decreased band gap of UV light.

In this study, polymer composites based on polyvinyl borate (PVB) with titanium dioxide (TiO2) nanoparticles were prepared through the condensation reaction of polyvinyl alcohol and boric acid in the presence of TiO2 nanoparticles. The solid-phase photocatalytic degradation of the polymer composites under UV light irradiation was investigated and compared with that of the pure PVB with the aid of weight loss measurements. The introduction of the photocatalyst nanoparticles in PVB enhanced the solid-phase photocatalytic degradation of the polymer matrix under UV light irradiation. The structural and morphological properties of PVB/TiO2 composites were analyzed by transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and UV-Vis spectroscopy, respectively. FTIR analysis revealed that PVB synthesis was successfully carried out in the presence of the photocatalyst nanoparticles. According to the morphological analyses, TiO2 nanoparticles were well dispersed in the PVB matrix.

TiO2/fine char (FC) photocatalyst was prepared via sol-gel method with tetrabutyl titanate as the precursor and FC as the carrier. The structural property of TiO2/FC photocatalyst was investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM), and the photocatalytic activity of TiO2/FC was evaluated by photocatalytic degradation of rhodamine B (RhB) aqueous solution under UV light irradiation. The results showed that TiO2was successfully coated on the surface of FC, and the TiO2/FC photocatalyst had better photocatalytic efficiency and stability for degradation of RhB under UV light illumination as compared to that of the pure TiO2and FC. The study provided a novel way for the application of FC to the photocatalytic degradation of organic wastes.
