Preparation and performances of successive TiO2 thin film photocatalyst supported on carbon fiber
Successive TiO2 film photocatalysts supported on surface modified PAN-carbon fiber (PAN-CF) substrates were prepared via the sol-gel dip-coating method with Ti(O4H9)4 as a precursor. Several techniques such as scanning electron microscope(SEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD) were utilized to investigate the optimized concentrations of Ti sol, annealing temperature and their influence on the final properties of the TiO2/CF. The interfacial bonding properties of carbon fiber with TiO2 film was evaluated by ultrasonic vibration. The results show that M5TiO2/CF has favorable load fastness and load rate. The photocatalytic properties of TiO2/CF were investigated by degrading acid orange II (80mg/L) under UV irradiation. The results suggest that the catalytic activity have significant difference compared with M3TiO2/CF>M5TiO2/CF>M7TiO2/CF and the M5TiO2/CF has been shows the optimum catalytic performances.
