| 摘 要： | 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）。通过选择卷烟主流烟气中巴豆醛为靶标分子，考察复合材料作为滤嘴添加剂对巴豆醛的吸附效果。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。实测卷烟结果显示，CTN/NaY样品对主流烟气中巴豆醛的去除率达到30.4%，具有广阔的应用前景。

Preparation of self-modeling composite material and its selectively adsorptive property on crotonaldehyde in mainstream cigarette smoke |

| Abstract: | During the hydrothermal synthesis process for preparing the mesoporous material, ethyl ether was introduced into the solution to form an emulsion system, which was helpful to promote self-modeling material. After adding the zeolite fragments into the synthetic system, series of self-modeling composite porous materials were prepared which named CTN/X (X=NaA, NaZSM-5, NaY). In order to investigate the adsorptive ability of these composite materials used as cigarette filter additives, the crotonaldehyde in mainstream cigarette smoke was selected as the target molecule. The results showed that the emulsion system was beneficial for self-modeling. The specific surface area of CTN/NaY reached to 832 m2/g, and the most probable pore size of CTN/NaZSM-5 was 4.3 nm. Compared with the control cigarette, the cigarette with these composite materials in the filter exhibited more excellent selectively adsorptive ability to crotonaldehyde in mainstream cigarette smoke, while the amount of nicotine and tar level in the test cigarette smoke changed a little. When the CTN/NaY sample was used as filter additive, the content of crotonaldehyde in mainstream cigarette smoke could be decreased about 30.4%. |
