Abstract
In this study, photo-catalytic degradation of methyl orange (MO) azo dye was examined by undoped and Ce2O3/ CuO/ N doped ZnO nanoparticles stabilized on γAl2O3. Highest photo-catalytic activity was observed for the N-doped 10 wt. % ZnO-γAl2O3 sample. One of the optimal points with the complete MO decomposition was determined at an initial concentration of 8.25 ppm, pH 3.25, catalyst loading of 0.36 g/L and 12.56 W UV-light irradiation after 120 min. Physical and chemical properties of materials were investigated by X-ray diffraction analysis (XRD), Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) and UV–visible diffuse reflectance spectroscopy (DRS) method. The experimental data were best fitted by a Langmuir-Hinshelwood approach photo-catalysis developed kinetic reaction rate in the form of
