Synthesis of a New Zeolite, Intergrowth of Erionite and Chabazite

A new zeolite, COK-24, which is an intergrowth of erionite (ERI) and chabazite (CHA), was successfully synthesized for the first time. This was realized via a mixed gel approach. The formation of an intergrowth was confirmed via XRD combined with advanced electron microscopy. The new zeolite intergrowth outperformed its individual counterparts in NH3-SCR reaction.
