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 X-ray 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.
