Enhanced visible light photocatalytic properties of Fe-doped TiO2 nanorod clusters and monodispersed nanoparticles

Solar-driven photocatalytic treatment of diclofenac using immobilized TiO2-based zeolite composites

“…The concentration of Fe out of these clusters is lower than the expected average (1.04 % in TiO 2 -FeZ-(27.5)), which is close to the detection limit of the applied method. DRS analysis of immobilized TiO 2 and TiO 2 -FeZ composite photocatalysts thin films is presented in ESM 1: Fig Such results are in accordance with the hypothesis that coupling of TiO 2 with transition metals would lead to lower band gaps (Chong et al, 2010;Pelaez et al, 2012;Liu et al, 2011) due to visible light-driven transfer of charge carries through the Ti-O-Fe heterojunction. An increase of FeZ wt% results in increase of iron content in the immobilized composite layer.…”

“…It is anticipated that the formation of TiO-O-Fe bonds would yield lower band gap and improved activity of composite material in comparison to Aeroxide TiO 2 P25 under solar irradiation (Lai et al, 2015;Liu et al, 2011). The coupling of TiO 2 with FeZ, as a microporous material, may increase the surface area and porosity of thin films, facilitating the generation of radical species (Fujishima et al, 2008;Noorjahan et al, 2004).…”

Comparative study of (N, Fe) doped TiO2 photocatalysts

“…In order to use the sunlight in the photocatalytic processes doping with metal or non-metal dopants such as Fe, Cr, V [9,10] or N, S, C [11][12][13] has become an alternative. New energy levels located in the intra-gap give rise to the reduction of the associated band-gap.…”

Preparation and optical properties of iron-modified titanium dioxide obtained by sol–gel method

“…. For example, Liu et al prepared the Fe-doped TiO 2 nanorod clusters and monodispersed nanoparticles by a modified hydrothermal and solvothermal method [23]. Shi et al [24] obtained Fe-La-TiO 2 photocatalysts by a sol-gel method.…”
