Synergistic effects of C, N, S, Fe-multidoped TiO2 for photocatalytic degradation of methyl orange dye under UV and visible light irradiations.
SN appl. sci. 1:930 (2019)
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.
