MESOPOROUS SILICA MATERIALS WITH CRYSTALLINE PORE WALLS AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A mesoporous silica material with a crystalline pore wall and a method for preparing the same are provided to improve the availability of the material and to adjust the amount of the crystalline pore wall according to the content of alkali metal ions. CONSTITUTION: A method for preparing a mesoporous silica material with a crystalline pore wall includes the following: alkali metal ions are added into mesoporous silica material with an amorphous pore wall; and the material is thermally treated at a pre-set temperature such that the crystalline structure of the pore wall is obtained and size adjusted pores are formed in the pore wall. The source of the alkali metal ions is one selected from NaCl, LiCl, KCl, CaCl_2, or MgCl_2.
