High yield synthesis of high-silica chabazite by combining the role of zeolite precursors and tetraethylammonium: SCR of NOx

The synthesis of chabazite with high solid yields is achieved by the rational combination of directing effects of a source of Si and Al coming from USY zeolites and the inexpensive tetraethylammonium. Moreover, Cu-CHA materials prepared by post-synthetic and "one-pot'' methodologies show high activity and stability for SCR of NOx.Financial support from the Spanish Government-MINECO through "Severo Ochoa'' (SEV 2012-0267), Consolider Ingenio 2010-Multicat, MAT2012-37160 and, Intramural-201480I015 is acknowledged.
