摘要：

Dual templating using aqueous cetyltrimethylammonium chloride/hydroxide (CTMA Cl/OH) and latex spheres was performed to prepare powders of bimodal silica molecular sieves with mesopore and macropore systems. The CTMA/Si ratio was chosen to generate a cubic mesopore of MCM-48 structure. According to high Brunauer-Emmett-Teller surface area, narrow pore size distribution, X-ray diffraction powder pattern and scanning electron micrographs. the cubic mesophase is located within the macropore walls, which is the characteristic of a hierarchical porous system.
