Controllable synthesis of aluminosilica monoliths with hierarchical pore structure and their catalytic performance
چکیده انگلیسی

Aluminosilica monoliths with bicontinuous macropores and interconnected mesopores were successfully prepared by a double-template technique. The influence on monolithic pore structures and acidic properties based on aluminum variety was studied in detail, which demonstrated that aluminum addition and water amount in starting compositions had great effects on the formation of hierarchical pore system with bicontinuous macropores and interconnected mesopores. In addition to bicontinuous macropores and plenty of mesopores, the obtained aluminosilica monoliths also possessed considerable acid sites for catalysis. And such aluminosilica monolith with proper acidity and good diffusion showed best performance on catalytic reaction of large molecules such as the cracking 1,3,5-triisopropylbenzene compared with other aluminosilica monolith.
