Abstract
Mesoporous anatase-brookite TiO2 doped with different Fe/Ti molar ratios were successfully synthesized. The prepared samples were characterized by XRD, FE-SEM, HR-TEM, diffuse reflectance UV–vis spectroscopy, Raman-Photoluminescence, XRF, and N2 adsorption-desorption isotherms (BET). The results showed that the addition of Fe dopant into TiO2 especially brookite phase has induced a red shift in optical absorption which narrowed the band gap from 2.97 eV to 1.59 eV. The prepared Fe-TiO2 samples have an anatase-brookite and mesoporous structure with a large surface area. This has led to the significantly higher photocatalytic activity performance of Fe-doped TiO2 in the photodegradation of RB5 under solar light irradiation.
