The X-ray diffraction, scanning electron microscopy, X-ray phototoelectron spectroscopy (XPS) and nitrogen adsorption measurements were used to characterize the samples. Doping with La3+ inhibited the transformation of anatase phase to rutile during calcination treatment and the growth of crystallite size. XPS analysis confirmed the presence of La3+ in the form of La2O3 on the surface of TiO2. The photocatalytic activity of La3+-doped TiO2 samples was investigated in terms of decolorization and degradation efficiencies of Acid Orange 7 (AO7) dye. It was found that doping with La3+ enhanced the photocatalytic activity of TiO2. The performance of doped samples was also evaluated using synthetic dye-bath effluent of AO7. Solar-driven La3+-doped TiO2 photocatalysis was found significantly efficient for the decolorization and degradation of AO7.eninfo:eu-repo/semantics/closedAccesscharacterizationdopingphotocatalystsArticle2314815710.1680/nme.13.000112-s2.0-85016289555Q3WOS:000218886800005N/A
