DOI: 10.1039/c8ra08624a
Abstract: In the present work, mesoporosity is introduced into highly siliceous HZSM-5 zeolites (SiO2/Al2O3 = 400) by a two-step path including desilication using NaAlO2 and TPAOH (tetrapropylammonium hydroxide) mixtures, followed by acid washing treatment. The physicochemical… read more here.
