摘要：以纯硅MCM-48为原料合成了表面氨基功能化的MCM-48材料,进行了X射线衍射(XRD)、氮气吸附、SEM扫描电镜和FT IR红外光谱等表征。FT IR和元素分析的结果表明,3-氨基丙基三乙氧基硅烷通过与纯硅MCM-48表面的Si-OH基团反应,使氨基嫁接在纯硅Si-MCM-48表面。XRD和N2吸附说明纯硅MCM-48在嫁接氨基后仍保持Ia3d立体结构,但与纯硅MCM-48相比,氨基功能化的MCM-48的比表面积、孔容和孔径均有所下降。将氨基功能化的MCM-48作为吸附剂加入卷烟的过滤嘴,对于主流烟气中氰化氢(HCN)具有很好的选择性吸附功能。
Amino functionalized MCM-48 mesoporous silica was successfully synthesized by post-synthesis treatment of pure silica MCM-48(Si-MCM-48),and was characterized by X-ray diffraction(XRD),nitrogen adsorption,scanning electron microscopy(SEM)and FT-IR spectroscopy.The results showed that amino groups were successfully grafted on Si-MCM-48 surface by the reaction between(3-aminopropyl)triethoxysilane and Si-OH groups on Si-MCM-48 surface,which was confirmed by the results from FT-IR spectroscopy and the elemental analysis.XRD and N2 adsorption results exhibited that the cubic Ia3 d structure of Si-MCM-48 was maintained after aminosilane grafting,but the specific surface area,pore volume and pore size of amino functionalized Si-MCM-48 decreased compared with Si-MCM-48.When amino functionalized Si-MCM-48 was added in the cigarette filter and used as the adsorbent,it possessed excellent performance for the selective reduction of HCN amount in cigarette mainstream smoke.
