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

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 hi...

Zusammenfassung: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.
