A very short-time synthesis of highly ordered MCM-41 molecular sieve was formulated by using cetyltrimethylammonium bromide (CTAB) as the template and silica gel from SiliCycle as the silica source. The physical properties of MCM-41 samples were characterized by X-ray diffraction (XRD), nitrogen physisorption, and transmission electron microscopy (TEM). The MCM-41 sample prepared in this study exhibited well defined long-range order and good hydrothermal stability. It was demonstrated that reducing the time of self-assembly step to 2 h during the synthesis had no unfavorable effect on the quality of MCM-41 materials.
以十六烷基三甲基溴化铵（CTAB）为模板，以SiliCycle的硅胶为硅源，制备了高度有序的MCM-41分子筛的极短时间合成方法。通过X射线衍射（XRD）、氮气物理吸附和透射电子显微镜（TEM）对MCM-41样品的物理性质进行了表征。本研究制备的MCM-41样品表现出良好的长程有序性和良好的水热稳定性。结果表明，在合成过程中将自组装步骤的时间缩短至2小时对MCM-41材料的质量没有不利影响。
