Title: Direct synthesis of high-aspect ratio zeolite nanosheets

Abstract

An example material includes a planar layer of MFI zeolite. The planar layer has a thickness in a range between 4 nm and 10 nm for at least 70% of a basal area of the planar layer. In one embodiment, the planar layer includes an embedded particle of an MFI zeolite.
