Photocatalytic properties
Reusable - Opis:
- TiO2 nanomaterial was prepared by precipitation method and sonication technique. The nanomaterial was characterized by HR-SEM with EDX, TEM, XRD, FT-IR and PL analysis. The photocatalytic activity of TiO2 was much better than that of TiO2–P25 under UV-light irradiation at 365 nm. The photocatalytic activity was evaluated from the photodegradation of malachite green (MAG). The influence of operational parameters such as the effect of catalyst loading dye concentration and chemical oxygen demand measurements had also been investigated. The Photodegradation was found to follow the pseudo-first-order kinetics. Hydroxyl radical formation in the mechanism was confirmed by fluorescence quenching technique. It was proposed that the catalyst is found to be stable and reusable.
