Nanosized MCM-22 zeolite using simple non-surfactant organic growth modifiers: synthesis and catalytic applications.

Non surfactant cyclic alkylammonium can selectively decrease the rate of crystal growth along the x-y crystal axes during the synthesis of MWW zeolite. This results in an ∼60 nm nanocrystalline zeolite that shows remarkable catalytic properties for the production of cumene.
