| Abstract: | With hexadecyltrimethylammonium bromide (C16TMABr) as templates, tetraethoxysilane (TEOS) and sodium silicate solution as silica sources, mesoporous molecular sieves MCM-41 with fine properties were synthesized in room temperature. The samples were characterized by XRD, N 2 sorption, FTIR,SEM and TG analysis. The results indicate the solid samples possess regularly hexagonal pore arrangement, high specific area, pore volume, and thermal stability. |
