摘要:
以工业副产氟硅酸为硅源,九水合硝酸铝(Al(NO3)3·9(H2O))为铝源,十六烷基三甲基溴化铵 (CTAB)为模板剂,在溶胶混合物的组成为:n(SiO2)∶n[Al(NO3)3·9(H2O)]∶n(NH3·H2O)∶n(CTAB)= 1∶0.01-0.10∶10∶0.25-1.00∶150(摩尔比)的条件下,水热合成含铝硅基介孔分子筛Si/Al-MCM-41. 对水热合成过程中的Si/Al比,模板剂的用量,水热温度和时间等条件以及模板剂的脱除方式对分子筛结构的影响进行了研究. 并通过X射线荧光光谱仪,氮气吸脱附,透射电镜,热重分析等对样品进行表征. 结果表明:在合成条件为: n(CTAB)/n(Si)=2,水热温度70 ℃,时间5 h得到的样品的比表面积和孔体积较大,分别为1 086 m2/g和0.70 cm3/g.
Abstract:
The mesopore aluminosilicate MCM-41 was prepared by a hydrothermal method using the industrial by-product hexafluorosilicic acid as silicate source, Al(NO3)3·9(H2O) as aluminium source, and hexadecyl trimethyl amonium bromide (CTAB) as the templates with the molar ratios of n(SiO2)∶n[Al(NO3)3·9(H2O)]∶n(NH3·H2O)∶n(CTAB)=1∶0.01-0.10∶10∶0.25-1.00∶150. The effects of the content of Si/Al ratio, template amount, hydrothermal temperature and time, and removal ways of the template on the physico-chemical properties of MCM-41were investigated. The MCM-41 was also characterized by X-ray diffraction, N2 adsorption-desorption, transmission electron microscopy and thermal gravimetric measurements. The results show that the specific surface area and pore volume of the molecular sieve,which were prepared with the n(CTAB)/n(Si) mole ratio of 2 at 70 ℃ for 5 h, reach 1 086 m2·g-1 and 0.70 cm3·g-1, respectively.
