Abstract:Nonthermal plasma (NTP) enhanced catalytic oxidation of diesel particulate matter (DPM) is promising for applications. The synergistic effects of transition metal oxides (MOx, M = Mn, Cu, Ce, Fe, Co, Ti) and dielectric barrier discharge (DBD) plasma on DPM oxidation were investigated, and Fe2O3 showed the best synergistic effect. Cobalt‐doped iron oxide (Co–FeOx) displaying a spinel structure showed the best performance among M–FeOx (M = Co, Ce, Cu, Zn, Mn). The main intermediate product generated during the c… Show more
