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
