Abstract

In order to reduce the harmful constituents in cigarette smoke, two hierarchical composites were synthesized. Based on, zeolites HZSM-5 or NaY fragments were introduced into the synthetic system of mesoporous silica SBA-15 or MCM-41 and assembled with the mesoporous materials. These porous composites combine the advantages of micro- and mesoporous materials, and exhibit higher effects than activated carbon on reducing tobacco specific nitrosamines (TSNA) and some vapor phase compounds in smoke.

摘要

为了减少香烟烟雾中的有害成分,合成了两种分级复合材料。基于此,将沸石HZSM-5或NaY碎片引入介孔二氧化硅SBA-15或MCM-41的合成体系中,并与介孔材料组装在一起。这些多孔复合材料结合了微孔和介孔材料的优点,在减少烟草特有亚硝胺(TSNA)和烟雾中的一些气相化合物方面比活性炭表现出更高的效果。
