Efficient removal of volatile organic compounds by using visible light responsive WO_3 photocatalyst hybridized with zeolite adsorbents

成功地制备了负载沸石吸附剂的可见光响应型WO3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(MOR)能有效地提高WO_3在太阳光照射下氧化各种VOCs的光催化活性。而且，纯WO_3样品的比表面积较小，不能吸附大量有机物。相比之下，与MoR沸石杂化的WO_3可以较长时间地去除气相中稀疏扩散的VOCs。

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.
