在水热合成法制备介孔材料的过程中，通过使用醚类物质创造微乳环境，促进材料自成型，并在后期添加微孔沸石，制备了具有复合孔结构的吸附材料CTN/X（X=NaA，NaZSM-5，NaY）。考察复合材料作为滤嘴添加剂对卷烟主流烟气中巴豆醛的吸附效果。结果表明：微乳环境可以促进复合材料自成型；CTN/NaY样品的比表面积达到832 m2/g，而CTN/NaZSM-5的最可几孔径达到4.3 nm。与对照卷烟相比，复合材料对试验卷烟的焦油和烟碱量改变较小，对主流烟气中巴豆醛则具有较好的选择性吸附作用。

Ethyl ether was introduced in hydrothermal synthesis process when mesoporous material was prepared. An emulsion system was formed to promote self-modeling. After adding zeolite fragments into synthetic system, series of self-modeling composite porous materials were prepared which named CTN/X (X=NaA, NaZSM-5, NaY). The adsorptive ability of these composite materials when used as cigarette filter additives was investigated. Crotonaldehyde in mainstream cigarette smoke was set to be target molecule. Results showed that emulsion system was beneficial for self-modeling. Specific surface area of CTN/NaY reached 832 m2/g, and the most probable pore size of CTN/NaZSM-5 was 4.3 nm. Compared with controls, cigarettes with filters added these composite materials exhibited excellent selectively adsorptive ability to crotonaldehyde in mainstream cigarette smoke, while nicotine and tar level in test cigarette smoke changed a little. When CTN/NaY sample was used as filter additive, crotonaldehyde content in main stream cigarette smoke could be reduced by 30.4%.
