Abstract :
Cu-Mn-O catalysts were prepared by co-precipitation and hydrothermal method at the different calcination temperature. These catalysts were characterized by BET, XRD, SEM and the catalytic activity for the reduction of NO by propane was evaluated. XRD results showed that Cu1.5Mn1.5O4 was the main phase in all these samples. The NO conversion over the catalysts prepared by hydrothermal method was markedly higher than that by co-precipitation method. SEM analysis revealed that the grain size of the obtained catalysts by hydrothermal method was smaller.
