Hierarchical MFI zeolite was synthesized following a synthesis route using organic - inorganic hybrid surfactants; the resultant zeolite with mesoporous/microporous hierarchical structure exhibited remarkably high resistance to deactivation in catalytic activity of various reactions such as isomerization of 1,2,4-trimethylbenzene, cumene cracking, and esterification of benzyl alcohol with hexanoic acid, as compared with conventional MFI and mesoporous aluminosilicate MCM-41. ; This work is supported by the Ministry of Science and Technology through the Creative Research Initiative Program. ; 생명화학공학과 ; 화학과
