Abstract

Discrimination against the majority: The broad size distribution of conventional near-cubic Si-CHA (all-silica chabazite) zeolites impedes the formation of a close-packed layer, which is critical for the manufacture of zeolite films by secondary growth. Although present in lower abundance, platelike Si-CHA particles cosynthesized with near-cubic particles were deposited selectively on an α-Al2O3 disk to form a uniform layer.
