具有多级孔道结构、高水热稳定性的含氧化镁Silicalite-1分子筛的合成OA北大核心CSCDCSTPCD
Synthesis of Hierarchical MgO-Containing Silicalite-1 Zeolites with High Hydrothermal Stability
通过焙烧将分散在多孔氧化硅母体中的硝酸镁转化成高分散的MgO物种，然后使用四丙基氢氧化铵(TPAOH)作为结构导向剂，将含MgO的母体通过水热晶化合成MgO/silicalite-1分子筛复合物。 X射线衍射(XRD)、能量X射线光谱(EDX)和透射电镜(TEM)的结果表明MgO物种被均匀地分散在silicalite-1分子筛晶体中。将酸处理脱除氧化镁前后的样品在100%水蒸汽800°C条件下老化，结果表明MgO的引入有效地提高了分子筛的水热…查看全部>>
Hierarchical MgO/silicalite-1 composites were synthesized via hydrothermal treatment of MgO-supported porous silica using tetrapropylammonium hydroxide (TPAOH) as a template. MgO species were introduced into porous silica via solid-state grinding and subsequent calcination. X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM) results indicated that MgO was uniformly distributed in the zeolite cryst…查看全部>>
