Abstract:
The ordered bimodal mesoporous silica MCM-48 spheres were facile synthesized by mild-temperature post-synthesis H2O2 hydrothermal treatment of as-synthesized MCM-48. The results showed that H2O2 is indispensable for simultaneously removing organic templates and forming ordered bimodal mesoporous silica MCM-48 spheres. The bimodal mesoporous MCM-48 was characterized by X-ray diffraction, transmission electron micrographs, FT-IR, and N2 adsorption-desorption, and a possible mechanism was proposed for the formation of bimodal mesoporous MCM-48.

摘要:
在温和的条件下,通过H2O2水热处理预合成的MCM-48,得到了有序的双峰介孔硅MCM-48球. 结果表明H2O2对于同时去除有机模板剂及形成双峰介孔硅MCM-48球具有重要的作用.采用XRD、TEM、FT-IR和N2吸附-解吸等方法对双峰介孔MCM-48材料进行了表征,对双峰介孔MCM-48的形成机理也进行了探讨.
