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.

成功制备了分子筛吸附剂杂化的可见光响应WO_3光催化剂。在各种沸石中，具有疏水表面性质的硅质丝光沸石（莫尔）可以有效地提高WO_3在太阳光照射下氧化各种VOCs的光催化活性。纯WO_3样品比表面积小，不能吸附大量的有机物。相比之下，与莫尔分子筛杂化的WO_3可以在较长时间内去除气相中弥散的VOCs。
