Revisiting the nature of Cu sites in the activated Cu-SSZ-13 catalyst for SCR reaction

Cu-SSZ-13 is a highly active NH(3)-SCR catalyst for the abatement of harmful nitrogen oxides (NO(x), x = 1, 2) from the exhausts of lean-burn engines. The study of Cu-speciation occurring upon thermal dehydration is a key step for the understanding of the enhanced catalytic properties of this materi...
