【 摘 要 】

References(5)Cited-By(2)Zirconium was introduced to MCM-41 and MCM-48 in order to improve the resistance to alkaline solution. In this research, zirconium-containing mesoporous silicas (Zr-MCM-41 and Zr-MCM-48) were synthesized from tetraethylorthosilicate (TEOS), zirconium(IV)propoxide (ZrPr), sodium hydroxide (NaOH), the quaternary ammonium surfactant (cetyltrimethylammoniumbromide: CTAB) and deionized water. The XRD, TEM and nitrogen adsorption measurements show that zirconium-containing products have high quality of ordered structure of MCM-41 and MCM-48. The pore volume and the specific surface area of Zr-MCM-41 and Zr-MCM-48 are similar to those of pure silica samples. These materials show high stability in the alkaline solutions.
