| description | The invention discloses a medium/low-temperature core-shell denitration catalyst and a preparation method and application thereof, belonging to the technical field of air pollution control. Main raw materials consist of a titanium-based nano tube, soluble salt of cerium and soluble salt of manganese, wherein a carrier shell of the catalyst is formed by the titanium-based nano tube, and an active nanoparticle core is formed by oxides of cerium and manganese. The molar ratio of the total amount of cerium and manganese to the amount of titanium is (0.02-0.12):1, the molar ratio of cerium to manganese is more than 0.5 or less than 0.25, and when the molar ratio of cerium to manganese is between 0.25 and 0.5, the catalyst has good activity in a medium-temperature zone, a low-temperature zone and a medium/low-temperature zone. The preparation method comprises the steps of soaking the titanium-based nano tube in an organic solvent, adding the soluble salt of cerium and the soluble salt of manganese, impregnating, dr |
