Abstract: TiO2/zeolite composite photocatalysts were prepared in the water with natural zaolite and TiCl4, and the structure characterization was carried
out by X-ray, IR and TG-DTA. Their photcatalytic reactivity was studied by the methyl orange and methylene blue solution decomposition effect under the sun.
The results confirm that the anatase forms on the zeolite surface, and the mineral structure changes and the photocatalytic effect of low temperature
treatment is more excellent than that of higher temperature treatment, the decolouration rate is in the vicinity of 100%, and can be repeatedly used.

Key words: natural zeolite, TiO2, composite structure, decoloration rate
