Zeolite-based catalysts for oxidative upgrading of methane: design and control of active sites

Abstract

Oxidative upgrading of methane into carbon monoxide, methanol, lower hydrocarbons (such as ethane and ethylene), and other oxygenates has been achieved at relatively low temperatures over zeolite-based catalysts. The high...

Formation of paired Ga sites in CHA-type zeolite frameworks via a transcription-induced method

“…, zeolites), such as acidic properties, thermal stability, catalytic performance, and ion-exchange properties. 1 The isomorphous substitution of trivalent heteroatoms into zeolite frameworks generates ion-exchange sites in a one-to-one correspondence for charge compensation. Because isomorphously substituting heteroatoms are typically isolated from each other in zeolite frameworks, ion-exchange sites on such heteroatoms capture monovalent cations.…”
