Isolated Cu~(2+) ions: active sites for selective catalytic reduction of NO

摘要

Cu chabazite catalysts show remarkable low temperature activity in selective catalytic reduction (SCR) of NO. This high activity is due to the unique character of the zeolite framework that allows only the presence of one type of isolated mononuclear Cu~(50) species. These Cu~(2+) species are the active sites for SCR.
