Activity enhancement of zeolite MCM-22 by interlayer expansion enabling higher Ce loading and room temperature CO oxidation†
Layered zeolite precursor MCM-22P can be stabilized as interlayer expanded structure MWW-IEZ with enlarged pores by silylation producing –O–Si(OH)2–O– bridges. It adsorbs two times more cerium than MCM-22 and becomes activated for CO oxidation to CO2 at room temperature. This represents one of the most notable activity enhancements upon modification of layered zeolites.
