利用十二胺(DDA)为模板,以S0I0为合成路线,通过两步合成法在无机骨架上引入Al源,最终合成出超微孔(1.0~2.0nm)硅铝分子筛.分别用X射线粉末衍射技术、N2吸附脱附实验测定其物相结构及孔径尺寸.实验结果表明:合成的超微孔硅铝分子筛的d100值为2.94nm,其相应孔径尺寸约为1.7nm,是一种真正意义上的超微孔分子筛.
利用十二胺(DDA)為模闆,以S0I0為閤成路線,通過兩步閤成法在無機骨架上引入Al源,最終閤成齣超微孔(1.0~2.0nm)硅鋁分子篩.分彆用X射線粉末衍射技術、N2吸附脫附實驗測定其物相結構及孔徑呎吋.實驗結果錶明:閤成的超微孔硅鋁分子篩的d100值為2.94nm,其相應孔徑呎吋約為1.7nm,是一種真正意義上的超微孔分子篩.

Based on the S0I0 templating pathway, super-microporous (1.0~2.0nm) aluminosilicate molecular sieves was synthesized by dodecylamine(DDA)as the template, in which Al was incorporated into the inorganic framework by two-step method. The XRD and N2 adsorption-desorption measurements were used to characterize its structural properties and the pore size. The results show that the prepared molecular sieves possess the d100 spacing of 2.94 nm, and the pore diameter of it is about 1.7nm, demonstrating the excellence of it as the super-microporous molecular sieves.
