Single-unit-cell thick zeolite nanosheets (2-dimensional zeolites; AIChE Journal 60(7), 2374-2381 (2014)) with intact crystal and micropore structure can be made by exfoliation (Science 334, 72-75 (2011)). Recently, few-unit-cell thick zeolite nanosheets were prepared by direct synthesis (Nature 543, 690-694 (2017)). The nm-thickness and high aspect-ratio of these microporous nanosheets open exciting possibilities for technological breakthroughs in molecular sieve membrane fabrication (Johnson and Koros, Journal of the Taiwan Institute of Chemical Engineers 40(3), 268-275 (2009)). Recent progress on synthesis of high aspect ratio zeolite and other crystalline nanoporous nanosheets, methods to characterize their structure and properties, along with their processing and assembly to create membranes and catalysts will be the focus of this talk.
