英文摘要: Abstract(#br)A series of selected TiO 2 -Zeolite hybrid photocatalytic materials have been systematically synthesized and analyzed. The synthesized samples were characterized by X-ray diffraction (XRD), elemental analysis (ICP-OES), N 2 adsorption–desorption isotherms, diffuse reflectance UV–Vis spectroscopy (DRS), and transmission electron microscopy (STEM/HAADF/EDS/EELS). The photocatalytic activity of the samples was tested for the degradation of methyl orange (MO) and real wastewaters from the textile industry of Ethiopia. A 10% loaded TiO 2 -Zeolite Y (CBV 760) yielded up to 20 times higher mass normalized turnover rate (TORm) than pristine TiO 2 . The reusability of this photocatalyst was tested and only a 5% decrement was observed after three cycles. Furthermore, the photocatalytic...
