At last PAMAM dendrimers of half generations were used as organic template to tune the pore structure. Mesoporous Y -alumina of the MSU-n structure type with surface area(~300m2/g) and pore size(~4nm) have be synthesized.

• 最后用合成的半代PAMAM树枝状高分子作为有机模板剂对介孔氧化铝的孔结构进行调节，制备出孔道结构为蠕虫状，类似于MSU-n系列介孔材料的介孔氧化铝。
