| description | The invention discloses a Ce modified Co-Mn material as well as a preparation method and application thereof, and belongs to the technical field of catalytic treatment of tail gas pollutants of mining diesel vehicles. The preparation method of the Ce modified Co-Mn material comprises the following steps: mixing a cobalt salt, a manganese salt, a cerium salt, a dispersing agent and a complexing agent, and heating to obtain the Ce modified Co-Mn material, the complexing agent is polyvinylpyrrolidone. The PVP is adopted as the complexing agent, the cobalt salt, the manganese salt, the cerium salt and the complexing agent are dispersed in the dispersing agent, the formed product structure is a cauliflower-shaped surface structure with a high specific surface area, and the contact efficiency between the active component and the pollution gas is remarkably improved. According to the Ce modified Co-Mn material prepared by the invention, efficient removal of NO is realized, and the problems of high cost, easy generat |
