In this study, Fe-doped TiO2 nano-photocatalyst was successfully fabricated via a green synthesis approach for wastewater treatment. The structural, morphological, surface, and optical properties of the prepared nano-photocatalyst were comprehensively characterized, demonstrating promising potential for industrial wastewater purification treatments.
In light of the applications of nanotechnology in wastewater treatments, an attempt is made to fabricate the Fe-doped TiO2 nano-photocatalyst via simple and cost-effective sol-gel auto ignition route by following the green synthesis approach. The prepared nano-photocatalyst samples are characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), BET, and UV-Vis spectroscopy in order to study the structural, morphological, surface, and optical properties. XRD analysis validates the anatase phase formation and nanoscale structure of the prepared nano-photocatalyst. The spherical shaped grain morphology with some agglomeration is visualized in SEM image. The high specific surface area values are observed from the N-2-adsorption/desorption curves of the prepared samples. Further, the photocatalytic performance of the prepared nano-catalyst samples is evaluated by measuring the percentage degradation of toxic dye (Rhodamine B) under UV light radiation. The degradation rates as 98.7% and 98.2% in 120 min are observed in the case of Rhodamine B for pure and Fe-doped TiO2 nanoparticles, respectively. The reusability of the prepared nanoparticles is evaluated for five cycles and it shows negligible changes in dye degradation. All these outputs show that prepared Fe-doped TiO2 nanocatalyst are promising for industrial wastewater purification treatments.
