Preparation and Characterization of Fe³⁺ / TiO₂ Thin Films Loaded Activated Carbon and Degradation of Methyl Orange

Abstract:

Sol - gel method and doped with Fe3+ modification techniques were used, prepared for high catalytic activity of iron-doped titanium dioxide nanoparticles,which loaded on the activated carbon for Degradation of Methyl Orange. Such as crystal structure, particle size, load morphology, chemical state and optical absorption characteristics of the doped titania nanoparticles were characterized by using XRD, SEM, and UV-Vis. Fe-TiO2 catalysts for visible light response and the catalytic degradation of methyl orange in water performance were studied. The results showed that: catalysts prepared were anatase, the particle size decreases with the more amount of iron-doped. The phenomenon of Fe3+-modified TiO2 red shift were obviously. Compared with the undoped catalyst,degradation of Fe3+-TiO2 containing activated carbon improved significantly both in the UV and fluorescent light.
