  • Zinc oxide nanoparticles immobilized on ordered (SBA-15) and disordered (KIL-2) mesoporous silicate supports
    Maučec, Darja ...
    ZnO is a well-known photocatalyst for the degradation of dyes in wastewater treatment by using UV and solar light. However, the recycling of ZnO semiconductor nanoparticles presents a problem. We ... tried to solve this problem by immobilizing ZnO nanoparticles on different porous silicate supports. Mesoporous ordered silicate SBA-15 and disordered silicate KIL-2 have already been found appropriate for host matrices for Ti02 nanoparticles. In this contribution we present the immobilization of ZnO nanoparticles on porous silicate supports for the photocatalytic degradation of dyes. We have deposited ZnO nanoparticles on SBA-15 and KIL-2 porous matrices with various Zn/Si ratios by using a Schlenk-line. The composites were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and nitrogen adsorption. The photocatalytic activity of these composite materials for the degradation of organic dyes will be tested in a laboratory reactor.
