Abstract
A series of mesoporous aluminosilicate materials with different Si/Al molar ratio was synthesized using citric acid as pore forming agent. The effect of varied aluminium content on the structural and acidic properties of the mesoporous aluminosilicate materials was characterized through N2 adsorption-desorption, 27Al-MAS NMR and NH3-TPD techniques. The results showed that the structural and acidic performances of the mesoporous aluminosilicate materials were strongly related to the aluminium content. Furthermore, the catalytic activity of the mesoporous aluminosilicate materials with different nSi/nAl ratio was studied by the alkylation of phenol with tert-butanol. Both the catalytic activity and the selectivity to major product 2,4-di-tert-butyl phenol increased with the addition of aluminium content from Si/Al molar ratio of 50 to 10.
