Structural analysis of green synthesized Fe doped TiO2 nanocomposites and their application to wastewater remediation

Pure and Fe-doped TiO 2 nanoparticles were synthesized through green synthesis route for wastewater remediation application. Pure and Fe-doped TiO 2 nanoparticles were further characterised through various techniques like XRD, SEM, and EDS. The XRD patterns indicate pure anatase phase with space group I 41/a m d through the Rietveld refinement. The average crystalline size of Fe-doped TiO 2 nanoparticles decreases with the increment in the concentration of doping. The high agglomeration of pure and Fe-doped TiO 2 nanoparticles is observed through SEM. EDS analysis conforms the presence of Fe, Ti, and O elements in the nanoparticles. The photo catalytic activities of pure and Fe-doped TiO 2 under ultraviolet (UV) light with different concentration were investigated. The dissolved oxygen in the water increases with the increment of Fe doping and time of exposer of UV light.
