ZnO-SiO₂/Laponite Photocatalyst: Kinetic Study on Photocatalytic Decolorization of Methylene Blue

Abstract:

ZnO-SiO₂/Laponite was prepared by sol-gel preparation procedure consit of SiO₂ pillarization to laponite followed by ZnO dispersion by using zinc acetate as precursor. The obtained material was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), diffuse reflectance UV-Visible (DRUV-Vis) and N₂ adsorption-desorption analysis. The photocatalytic performance of the amterial in methylene blue decolorization was also investigated. Compared with ZnO-SiO₂ nanoparticles, it is concluded that ZnO-SiO₂/Laponite possess higher photocatalytic activity which obey Temkin isotherm model.
