We report on the mechanism of growth of mesoporous silica (SBA-15, plane group p6m). In situ studies of the formation using ultrasmall angle X-ray scattering (USAXS) and small-angle X-ray scattering (SAXS) covering length scales from 5 to 10,000 A, complemented with UV-vis and transmission electron microscopy (TEM), provide unique data on particle growth coupled with information regarding the progression of the mesostructure formation and the micellar evolution.
我们报道了介孔二氧化硅（SBA - 15，平面群p6m）的生长机制。使用超小角X射线散射（USAXS）和小角X射线散射（SAXS）对形成过程进行原位研究，其覆盖的长度尺度范围为5至10000埃，并辅以紫外可见光谱和透射电子显微镜（TEM），提供了关于颗粒生长的独特数据，以及有关介观结构形成过程和胶束演化的信息。
