Abstract
Titanium dioxide doped Fe3+ and La3+ nano-composite films were prepared using the solâgel method. The photo-catalytic properties were evaluated by photo-degradation of methyl orange in solution. Scanning electron microscope, X-ray diffraction, and energy dispersive spectrometer were used to characterize the TiO2 film doped Fe3+ and La3+, indicating that the film has nano-structure, and mainly anatase crystal. It is proved that co-doped Fe3+ and La3+ can improve significantly the photo-catalytic properties of TiO2 film due to the synergistic effect of the two ions.
