摘要
以离子液体1-十六烷基-3-甲基溴代咪唑为模板剂,合成介孔分子筛MCM-41。考察了不同硅源[、C16mim]Br/SiO2配比、pH值、晶化时间等条件对合成MCM-41的影响。采用XRD和低温氮吸附对产物进行表征,结果表明该方法合成的样品具有较大比表面积和规整介孔孔道结构。
Mesoporous molecular sieves MCM-41 has been synthesized using 1-hexadecane-3-methyl-imidazolium bromide as a template.The effects of different Si sources,[C16 mim]Br/SiO2,pH and crystallization time on synthesis of MCM-41.The structure of MCM-41 was characterized by X-ray diffraction and N2 adsorption-desorption.Results show that these mesoporous materials possess higher surface area.
