| Research Abstract |
The visible light responsive WO_3 photocatalysts hybridized with zeolite adsorbents were successfully prepared. Among various zeolites, the siliceous Mordenite (MOR) having a hydrophobic surface property could effectively enhance the photocatalytic reactivity of the WO_3 to oxidize various VOCs under sunlight irradiation. As well as, the pure WO_3 sample having a small surface area could not adsorb large amount of organic compounds. In contrast, the WO_3 hybridized with the MOR zeolite could remove VOCs thinly diffused in gas phase for a prolonged period.
