Abstract

Abstract : SAPO-34 (CHA-type) was subjected to treatment with a mixed NH4 F–HF aqueous solution resulting in a hierarchical micro-mesoporous material with retained intrinsic properties. Abstract : SAPO-34 crystals are etched in fluoride medium. The interface between crystalline domains is dissolved and yields a hierarchical material with a system of straight intersecting mesopores that improve the access to micropore space.
