Paper Title:
Synthesis of SBA-15 within Short Reaction Time
  Abstract

Mesoporous molecular sieves SBA-15 was synthesized by using tetraethyl orthosilicate (TEOS) as silica source and pluronic 123 (EO20PO70EO20) as a template within short reaction time (6 hours) in acidic media. The influences of the different synthesis parameters such as crystallized time and crystallized condition was investigated .The resultant samples were characterized through XRD and Nitrogen adsorption. The results showed the well ordering channels SBA-15 can be synthesized under air atmosphere within 6 hours, and the best proportion could be obtained with 1 TEOS: 0.010 P123:2.17 HCl:231 H2O. After heating at 1273K for 2 hours and boiling at 373K for 24 hours, the calcined SBA-15 was proved there is well stability.
