Abstract

In this paper, a novel nickel foam supported MnO2@CeO2 core-shell catalyst was prepared using nickel foam as the carrier and MnO2@CeO2 as the active component. The catalyst structure and properties were characterized by XRD, TEM and SEM. The catalyst was then applied to SCO flue gas denitration. The results showed that the 10% nickel foam supported MnO2@CeO2 core-shell catalyst and the loading time of 6 h showed excellent structural performance and stability with a denigration rate of 97%; the MnO2@CeO2 core-shell catalyst with the loading of 10% had a relatively more uniform surface roughness than the others, allowing a large amount of reaction gas to be denitrified at the same rate and improving its denitration efficiency.
