A great approach for the preparation of TiO2 supported on HZSM-5 photocatalyst was employed by an energy efficient microwave assisted technique. Titanium tetraisopropoxide (TTIP) was used as a titanium precursor and medium pore size HZSM-5 with high thermal and chemical resistance used as a support. The amount of TTIP was varied in order to obtain different TiO2 loading of 20, 30 and 40 wt% on HZSM-5. The obtained nanomaterials were studied by a set of complementary characterization techniques including X-ray diffraction, transmission electron microscopy, scanning electron microscopy, energy dispersive spectroscopy, Fourier transform-infrared spectroscopy, surface area measurement (BET) and diffuse reflectance spectroscopy. The present research is mainly focused on the enhancement of surface area of TiO2 nanoparticles by using HZSM-5 as a support. The obtained nanomaterials were tested for the degradation of Acid Green 25 under UV light (365 nm). A maximum 96 % photodegradation of dye was achieved by utilizing most efficient TiO2(30 %)/HZSM-5 at 0.1 g/dm(3) catalyst within 60 min under UV light.
