    摘要: Novel lamellar mesoporous silica compositions which can contain functional inorganic elements and organic functional groups as part of the lamellar silica framework structure are described. The compositions are prepared using gemini amine surfactants as templates or structure directing agents. The compositions have novel high temperature and hydrothermal stability and unique fundamental particle structures.
