A method of supporting TiO2 on zeolite, without losing the photosensitization of TiO2 and the adsorption properties of zeolite, is the important aspect while preparing zeolite-based photocatalysts. Titanium(IV) oxide with different amount was supported on HZSM-5 zeolite using solid state dispersion (SSD) method. The photocatalytic activity of these systems in the degradation of acid red 114 indicates that TiO2/HZSM-5 (SSD) is an active photocatalyst; the optimum photodegradation activity is seen at 10–۱۵ wt.% TiO2/HZSM-5.Based on these results, a model highlighting the photodegradation activity of immobilized [TiO2/HZSM-5 (SSD)] TiO2, which may lead to the development of an easy and effective technology in wastewater treatments, is proposed.
