Abstract New titanium dioxide (Ti02) based catalysts were prepared by impregnating commercial zeolites in pellet form using a sol-gel technique. Modifications of surface area and adsorption properties were checked using BET measurements, together with single component adsorption equilibrium experiments for two model volatile organic compounds. Scanning electron microscopy investigations testified that TiOz happened to fix on the inert binder leading to a close intimacy of mixing with the zeolites crystallites. A diffusion cell was used to produce dilute polluted airstreams for dynamic experiments, in which adsorption and photodegradation phases were alternatively carried
