摘要: Abstract Photocatalytic titanium dioxide (TiO 2 ) nanocomposites with different loads of ozonated graphene (OGn) were prepared and evaluated in the photocatalytic degradation methylene blue, methyl orange ketoprofen using UVC irradiation. The characterized by field emission gun scanning electron microscopy (FEG-SEM), Raman spectroscopy, X-ray diffraction (XRD) thermogravimetric analysis (TGA-DTA) specific surface area was determined Brunauer-Emmett-Teller (BET) method. showed better activity than bare TiO due to enhanced adsorption property inhibiting recombination between photogenerated electrons holes. composite containing 8% wt. OGn -OGn-8%) supported on autoclaved cellular concrete (ACC) creating a floating nanocomposite. This material for successive cycles solutions. Although decreased each cycle, it is possible reuse nanocomposite satisfactorily this facilitates its practical application water treatment.
