Abstract

The aim of this work is the synthesis and characterization of C, N, S–Fe multidoped TiO₂ photocatalysts. The nanoparticles were prepared by sol–gel method and investigated by X-ray diffraction (XRD), transmission electron microscopy, UV–visible diffuse reflectance spectroscopy (DRS) and N₂ adsorption–desorption isotherm (BET). Photocatalytic activity of the photocatalysts was studied by degrading methyl orange (MO) under UV and visible light irradiations. XRD analysis illustrated that all synthesized samples present the anatase phase. CNS–0.3Fe-doped TiO₂ exhibited the highest surface area of 891 m²/g. DRS showed that Fe doping had efficiently narrowed the band gap to 2.74 eV and broaden the visible-light response region. The synthesized nanomaterials exhibited high photodegradation ability in the decomposition of MO than commercial pure TiO₂ nanoparticles Degussa P25.
