英文摘要 | Mesoporous aluminosilicates msu-s-mfi with well-ordered hexagonal symmetry were assembled from mfi zeolitic precursors containing abundant protozeolitic nanoclusters. normal mcm-41 was synthesized by using tetraethyl orthosilicate (teos) and sodium aluminate as silica source and aluminum source, respectively. the pore diameter of msu-s-mfi sample and normal mcm-41 both are 2.70 nm, and their bet specific surface areas and pore volumes are comparable as seen from xrd and n-2 sorption results. although both msu-s-mfi and mcm-41 possess weak acidic sites and medium strong acidic sites in nh3-tpd profiles, the density of weak acidic sites and medium strong acidic sites in msu-smm are much higher than that of mcm-41. the catalytic cracking conversion of cumene on msu-s-mfi is 31% higher than that on mcm-41 with the same si/al ratio, and the butylation conversion of naphthalene over msu-smm is 15% higher than that on the mcm-41 sample. incorporation of mfi zeolitic nanoclusters into the mesostructured framework of msu-s-mfi led to enhanced acidity. |
