Commercial Tio2

In this study, commercial and lab-prepared TiO2 were modified by fluorination and platinum photodeposition; and the effect of these modifications over the physicochemical and photocatalytic properties of TiO2 was evaluated. It was found that F and Pt addition leads to the modification of the optical and textural properties of TiO2. The materials prepared were tested in the photocatalytic degradation of different organic dyestuffs such as methylene blue (MB) and methyl orange (MO); the degradation of commercial anilines employed in the staining of natural fibers was also evaluated. Photocatalysis was also studied in this work as an eco-friendly treatment of wastewater coming from handicrafts factories. In general it was observed that the effectiveness of the photocatalytic treatment strongly depends on the substrate to be degraded, thus, fluorinated and platinized commercial Titania (Pt-F-P25) showed the best photocatalytic performance in the MB and MO photodegradation and in contrast, in the case of the anilines the highest degradation was obtained over commercial TiO2 fluorinated (F-P25). These results can be explained by differences observed in the structure and in the adsorption of these dyestuffs over the photocatalysts surfaces. F-P25 photocatalyst also demonstrated to be the best material for the treatment of real wastewater coming from handicrafts factories.

Er3+ doped ZnO-TiO2 nanofibers with diameter of 100～200 nm were prepared by electrospinning mothed after calcined at high temperature, using polyvinylpyrrolidone(PVP), Zn(NO3)2·6H2O, Er(NO3)3·5H2O, Ti(OC4H9)4 asraw materials. The composite nanofibers were characterized by XRD, SEM, and UV-V respectively. Effects of different calcined temperatures on structure and photocatalytic degradation were investigated. The results indicated that the crystallinity becomes better with the increasing of calcination temperature. The composite nanofibers had the best effects of photocatalytic degradation of methylene blue, when Er3+ doping content was 0.3 wt.% and calcined temperature was 500 °C.
