Abstract

The presented work reports the selective catalytic reduction (SCR) of NOxassisted by dielectric barrier discharge plasma via simulating marine diesel engine exhaust, and the experimental results demonstrate that the low-temperature activity of NH3-SCR assisted by non-thermal plasma is enhanced significantly, particularly in the presence of a C3H6 additive. Simultaneously, CeMnZrOx@TiO2 exhibits strong tolerance to SO2 poisoning and superior catalytic stability. It is worthwhile to explore a new approach to remove NOxfrom marine diesel engine exhaust, which is of vital significance for both academic research and practical applications.
