Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 2,   Pages 248-257 doi: 10.1007/s11705-019-1853-9

Abstract: Hierarchical ZSM-5 zeolite with radial mesopores is controllably synthesized using piperidine in a NaOHThe piperidine molecules enter the zeolite micropores and protect the zeolite framework from extensiveThe areas containing fewer aluminum atoms contain fewer piperidine protectant molecules and so they dissolveSmall amounts of mesopores are then gradually generated in areas with more aluminum atoms and more piperidineThe optimal hierarchical ZSM-5 zeolite, prepared with a molar ratio of piperidine to zeolite of 0.03,
