Copper(II) Ion-exchanged ZSM-5 zeolites as highly active catalysts for direct and continuous decomposition of nitrogen monoxide

Abstract

ZSM-5 zeolites containing Cu 2+ ions showed unusually high and steady state activity for the catalytic decomposition of nitrogen monoxide; for example, the degrees of conversions of NO, and of conversion into N 2 and O 2 were 97, 85, and 70%, respectively, at 823 K with a contact time of 10.0 g s cm -3 over 73% exchanged Cu-ZSM-5. © Royal Society of Chemistry.
