以十六烷基氯化吡啶为模板剂,甲酰胺为共溶剂,在室温酸性条件下合成了棒状有序纳米介孔二氧化硅,并用扫描电镜(SEM)、小角X射线衍射(SXRD)和N2气体吸附仪对其进行了表征。结果表明,棒状产物形貌规整,形态均一,长度约30～50μm,直径约5μm,具有MCM41的有序六方孔道结构;煅烧后的样品显示典型的Ⅳ型吸附等温线和H1型滞后环,孔径分布很窄,BJH最可几孔径为2.15nm,BET表面积高达1335m2·g-1。 Using cetylpyridinium chloride as template and formamide as co-solvent, rod-shaped ordered mesoporous silica was synthesized under acidic conditions at room temperature. The morphology of the mesoporous silica was characterized by scanning electron microscopy (SEM), small angle X-ray diffraction N2 gas adsorption instrument was characterized. The results showed that the morphology of the rod-like product was regular and homogeneous with a length of about 30-50 μm and a diameter of about 5 μm, with ordered hexagonal pore structure of MCM41. The calcined sample showed the typical type Ⅳ adsorption isotherm and H1 type hysteresis loop, The distribution is very narrow, BJH the most pore size of 2.15nm, BET surface area up to 1335m2 · g-1.
