Synthesis of hierarchical ZSM-5 zeolite using CTAB interacting with carboxyl-ended organosilane as a mesotemplate

A hierarchical ZSM-5 zeolite with uniform mesopores has been synthesized by self-assembly of zeolite seeds capped with carboxyl-ended organosilane. The carboxylate anion enhances the inorganic–surfactant interaction and enables the formation of mesopores.
