摘要: We have developed an efficient route for the synthesis of TiO2/Zn2TiO2/ZnO/C nanocomposites through a Pechini sol–gel method followed by heat treatment at 550 °C 30 min. The produced phases and their crystallite sizes been controlled varying Ti4+:Zn2+ molar ratios. FE-SEM, FT-IR, XRD, TEM, diffuse reflectance spectroscopy (DRS) thermal analysis techniques were utilized characterization as-prepared products. photocatalytic activity products was investigated. Superior observed nanocomposite degradation Orange G dye (OG) under sunlight UV illumination with ca. 100% in 50 120 min, respectively. kinetic studies showed that first-order rate constant (kobs) 113.48 × 10−3 29.46 min−1 irradiation, results also stability reusability its applicability removal OG textile from aqueous media.
