Preparation and photo-catalytic activity of nano-TiO2–ZSM-5 composite

Nano-anatase (TiO2) has been synthesized on ZSM-5 zeolite by the hydrothermal method. The produced composite was characterized using X-ray diffraction, FT-IR spectroscopy and Electronic Microscopic measurements, SEM and TEM. Synthesis of nano-TiO2 on the surface of zeolite causes high dispersion of particles over the zeolite framework and results in a higher rate of degradation of Brown-NG (an azo-dye) under UV irradiation as compared with TiO2 (P25). Degradation of the dye was measured by an UV–vis spectrophotometer.
