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

Abstract

Pure and Fe-doped TiO2 nanoparticles were synthesized through green synthesis route for wastewater remediation application. Pure and Fe-doped TiO2 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 TiO2 nanoparticles decreases with the increment in the concentration of doping. The high agglomeration of pure and Fe-doped TiO2 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 TiO2 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.
