英文摘要: Abstract(#br)Many great efforts have been devoted to the synthesis of hierarchically zeolites due to their potentially significant technological applications for catalytic reactions involving bulky reactant/products. In this work, we report a facile hydrothermal route to prepare mesoporous silicalite-1 with plentiful intracrystalline mesopores (5–20 nm) using poly (acrylic acid) (PAA) as a mesoscale template. During the crystallization process, the PAA chains served as the space occupant for intracrystalline mesopores, meanwhile, a small amount of amphiphilic organosilane (dimethyloctadecyl-[3-(trimethoxysilyl)-propyl]-ammonium chloride, TPOAc) acted as auxiliary template to enhance the connection between the growing crystal domains and the PAA chains. After calcination, the mesopore...
