Mordenite encapsulated with Pt-TiO2: Characterization and applications for photocatalytic degradation of direct blue dye

Ti-incorporated mordenite zeolite was prepared by ion-exchange method, while Pt was immobilized on the encapsulated titanium via impregnation method. The produced samples were characterized using Xray diffraction (XRD), Ultraviolet and visible spectroscopy (UV-Vis), Photoluminescence emission spectra (Pl), Scanning electron microscopy (SEM) and surface area measurement. Furthermore, the catalytic performances of Ti-Pt/ mordenite were carried out for degradation of direct blue dye using visible light. (C) 2013 Elsevier B.V. All rights reserved.
