Zirconium doped cerium vanadate denitration catalyst, preparation method and application

The invention discloses a zirconium doped cerium vanadate denitration catalyst which is characterized in that the denitration catalyst is a nano material having a rodlike or granular structure, wherein the mole ratio of zirconium doping amount to metal cerium is x:(1-x), and x is larger than 0.05 and less than 0.8. The invention also discloses a preparation method and application of the zirconium doped cerium vanadate denitration catalyst. The catalyst is prepared by adopting a hydrothermal process, is wide in operating temperature window, can reach NOx removing rate of 80% or above at the temperature of 150-375 DEG C, also has the advantages of good thermal stability, excellent H2O and SO2 poisoning resistance, simple preparation process, low cost and the like, is suitable for treatment of nitric oxide in a fixed source and a moving source and is applicable to practical application.
