Abstract |
In this research, Fe3+ was used to adjust TiO2 to give enhanced photocatalytic performance under visible and UV light. The TiO2 photocatalysts were prepared by a hydrothermal method without calcination route [1]. Box–Behnken design (BBD) was used to investigate the effects of Fe content (wt%), hydrothermal temperature and time on the photocatalytic performance of TiO2 [2]. Pollutants such as alachlor and reactive red 3 (RR3) dye were examined. The as-synthesized photocatalysts have been characterized by many analytical techniques. Photodegradation of RR3 dye was performed under UV light irradiation whereas degradation of alachlor was done under both UV and visible light irradiation. In RR3 degradation, the parameter of hydrothermal temperature and time were found significant and the highest removal percentages were 92 and 94% for 15 and 30 min, respectively. In alachlor degradation, the effect of Fe-doping was found significant under UV and visible light. The highest removal percentages were 49 and 82% for 15 and 30 min of UV light irradiation, respectively, and 51% for 60 min of visible light. Only anatase crystallite phase was found in catalysts. Energy band gaps decreased with increasing Fe contents. The crystallite sizes of catalysts with 0.10 wt% Fe3+ content decreased with increasing hydrothermal temperature and time, while surface area increased. Energy-dispersive X-ray spectroscopy technique was able to detect nitrogen contents of about 10 wt% and X-ray absorption near edge structure was used to find the oxidation states of Fe3+ and Fe3+/4+ in Fe-TiO2 as well.
