为选择性降低卷烟主流烟气中氢氰酸(H C N)的释放量,采用水热合成法制备了金属有机骨架(MOFs)多孔材料均苯三甲酸合铜(Ⅱ)(Cu-BTC),运用X射线粉末衍射(XPRD)、比表面积孔径分析(B E T)、热重分析(T G)等技术对材料的晶体结构、孔结构参数及热稳定性进行了表征,并将材料添加于卷烟滤嘴中进行了烟气减害测试。结果表明:①Cu-BTC是一种典型的MOFs多孔材料,在270℃以下具有良好的热稳定性。②在卷烟添加剂减害性能模拟评价条件下,Cu-BTC对卷烟主流烟气中HCN的降低效果可达51.9%;在卷烟应用试验中,Cu-BTC对卷烟主流烟气中HCN的选择性降低率为21.83%,而常规烟气成分释放量与对照卷烟基本一致。

To selectively reduce the delivery of hydrocyanic acid (HCN) in mainstream cigarette smoke, a porous material with metal-organic framework (MOF), copper-1, 3, 5-benzenetricarboxylic acid (Ⅱ) (Cu-BTC), was prepared by hydrothermal synthesis method. The crystal structure, pore structure and thermal stability of the prepared material were characterized by X-Ray powder diffraction, BET surface area analysis and thermal gravimetric analysis. The material was added into cigarette filter to test its harm reducing effect. The results showed that: 1) Cu-BTC was a typical MOF porous material with excellent thermal stability under 270 ℃. 2) Under the conditions of a simulated device for evaluating the harm reducing effects of cigarette additives, the reduction rate of HCN in mainstream cigarette smoke by Cu-BTC reached 51.9%; in a real cigarette experiment, the selective reduction rate of HCN by Cu-BTC was 21.83%, while the deliveries of routine components in cigarette smoke were basically similar to the control.
