Abstract: Abstract Pure and thin chabazite zeolite membranes were successfully prepared on macroporous symmetrical stainless steel supports by a two-stage varying-temperature hydrothermal synthesis. The morphologies and pervaporation properties of chabazite zeolite membranes were greatly influenced by… read more here.

DOI: 10.1021/jacs.2c03941
Abstract: Ga-chabazite zeolites (Ga-CHA) have been found to efficiently catalyze propane dehydrogenation with high propylene selectivity (96%). In situ Fourier transform infrared spectroscopy and pulse titrations are employed to determine that upon reduction, surface Ga2O3 is… read more here.
