The purpose of this study is to investigate the characteristics of the simultaneous removal of PM and NOx on the CuNb-ZSM-5 SCR/DPF catalysts coated onto DPF substrate. NOx conversion by the CuNb-ZSM-5 catalyst was higher than those by Cu- or Fe-ZSM-5 catalysts. NOx conversion of the SCR/DPF catalyst with a wall-flow (plugged) was considerably lower under 450 ℃ than that of the SCR/DPF catalyst with a channel-flow (unplugged). The de-NOx performance of the SCR/DPF catalyst coated with CuNb-ZSM-5 was highest among the catalysts examined. SCR/DPF catalyst coated with CuNb-ZSM-5 had superior PM oxidation performance compared to the other SCR/DPF catalysts.
