چکیده
In this work, undoped and Fe-doped TiO2 immobilized on kaolinite surface was successfully synthesized by sol-gel method with various Fe concentrations (0.05, 0.125, 0.25 wt%). The effects of doping into lattice were thoroughly investigated a diffuse reflectance UV-visible (DRS) spectroscopy, Fourier Transform Infrared (FTIR) X-ray diffraction (XRD). optical band gap TiO2/kaolinite is red shifted respect to the incorporation Fe3+ structure resulted gap. FTIR spectra shows shift peak at wave number 586 cm−1 774 which attribute Fe−O vibration as an indication formation Fe-TiO2 bonds. Incorporation cation replacing Ti4+ ions, induced perturbation in anatase crystal structure, causes change distance spacing lattices dhkl(101) 8.9632 7.9413. enhanced photocatalytic performance observed for compared Escherichia coli growth inhibition solution media under visible light irradiation.

متن کاملDegradation of Acetaldehyde with Doped TiO2 Photocatalyst Under Visible Light Irradiation
C-, V-doped TiO2 photocatalysts are prepared by a sol-gel process. These catalysts are highly active for the degradation of acetaldehyde both under visible irradiation (> 420 nm) and in the dark, especially for 2.0% V-containing co-doped TiO2. Characterization results suggest that vanadium ions are introduced both on the surface and into the bulk of TiO2. A free electron, induced by the formati...
