In this study, large pore size and highly ordered mesoporous molecular sieve SBA-15 was successfully synthesized in the acidic medium by using n-propanol as the pore-expanding agent, and tetraethyl orthosilicate (TEOS) as silicon source and poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) triblock copolymer (P123 triblock copolymer) as a template agent. The samples were characterized by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Nitrogen Adsorption-Desorption. It is found that the particles of mesoporous molecular sieve SBA-15 have regular morphology and ordered pore structure, and also have high specific surface area, large pore size and pore volume.
