Nitric acid rare earth catalyst preparation method

The present invention discloses a nitric acid rare earth catalyst preparation method, which comprises: dissolving 15 parts of zirconium, 2 parts of nickel, 2 parts of calcium, 40 parts of lanthanum oxide, and 5 parts of cerium oxide, mixing, precipitating, drying and decomposing the mixed precipitate, adding to solid solution powder with a general formula of (Y3Eu2SrAl2)O10, co-adding to water, grinding, drying, carrying out granulation forming, and calcining the formed catalyst for 5 h at a temperature of 800 DEG C. According to the present invention, the catalyst adopting the rare earth elements such as La, Ce, Co and Ni has the excellent property in the oxidation reaction, and can replace the platinum so as to reduce the production cost of the enterprise; and the substantially effects are provided for improvement of the catalyst catalysis efficiency and the conversion rate.
