“…The final percentages of RhB removed by TiO 2 /AC-1, TiO 2 /AC-2, and TiO 2 /AC-3 reach 82.0%, 93.2%, and 86.3%, respectively. The RhB removal rate of TiO 2 /AC composites is far superior for pure TiO 2 synthesized in this study or macroporous TiO 2 photocatalyst reported in our previous work [39].…”

Photocatalysts comprising nanosized TiO2particles on activated carbon (AC) were prepared by a sol-gel method. The TiO2/AC composites were characterized by X-ray diffraction (XRD), thermogravimetric (TG) analysis, nitrogen adsorption, scanning electron microscope (SEM), transmission electron microscope (TEM), and energy dispersive X-ray (EDX). Their photocatalytic activities were studied through the degradation of Rhodamine B (RhB) in photocatalytic reactor at room temperature under ultraviolet (UV) light irradiation and the effect of loading cycles of TiO2on the structural properties and photocatalytic activity of TiO2/AC composites was also investigated. The results indicate that the anatase TiO2particles with a crystal size of 10–20 nm can be deposited homogeneously on the AC surface under calcination at 500°C. The loading cycle plays an important role in controlling the loading amount of TiO2and morphological structure and photocatalytic activity of TiO2/AC composites. The porosity parameters of these composite photocatalysts such as specific surface area and total pore volume decrease whereas the loading amount of TiO2increases. The TiO2/AC composite synthesized at 2 loading cycles exhibits a high photocatalytic activity in terms of the loading amount of TiO2and as high as 93.2% removal rate for RhB from the 400 mL solution at initial concentration of 2 × 10−5 mol/L under UV light irradiation.

“…TiO 2 nanomaterials possess commendable performance in terms of its nontoxic, cost effectiveness, strong oxidizing activity, and long-term stability against photocorrosion, which have a very broad application prospect in many fields, such as air pollution, waste water treatment, hydrogen production, and sterilization [2][3][4][5][6][7]. The application of TiO 2 nanomaterials is greatly limited due to the poor visible light response and high charge recombination rate, originating from the wide band gap (3.2 eV for anatase and 3.0 eV for rutile) and the relatively high electrical resistance.…”

TiO 2 /carbon fiber composite is achieved by loading TiO 2 nanoparticles on biomass carbon fiber, which originates from the carbonized natural bast. The carbonized process and the loading amount of TiO 2 are researched in detail. It is found that the carbonized bast fiber shows robust adsorption characteristics for TiO 2 nanoparticles in aqueous dispersion, and TiO 2 nanoparticles with~15 wt.% in total weight are uniformly loaded onto the fiber surface. The photocatalytic properties of TiO 2 /carbon fiber composite are evaluated by photocatalytic degradation of rhodamine B and water splitting for hydrogen production. The results indicate that 90% RhB molecules could be attacked in 60 min under UV light irradiation, and the hydrogen production rate of water splitting is up to 338.51 μmol/h. The highlight is that TiO 2 /carbon fiber composite is easy to be recycled due to the incorporation of macroscopical biomass carbon fiber.

“…Although TiO 2 possesses high photocatalytic efficiency, it is always powder or particle, which may easily aggregate. In addition, the efficient recovery of TiO 2 from treated water is still a challenge [3][4][5][6][7]. Immobilizing TiO 2 on a porous solid surface, such as zeolites or activated carbon, can increase the efficiency of TiO 2 and solve the problem of hard recovery [8][9][10].…”

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.
