摘要
The present invention relates to a method of production of perovskite structure catalysts for high temperature decomposition of N2O, the catalysts having a general formula A1-xBxCyD1-yO3-δ and wherein A and B are selected from the group consisting of lanthanides, alkaline earth metals, Group III.A and IV.A metals, transition metals of groups IB, II.B, III.B, IV.B, VI.B, VIII.B and Bi;C and D are selected from the group consisting of transition metals of Groups IV.B, V.B, VI.B, VII.B, VIII.B, Lanthanides, Sn, Al and Sb;x and y are independent numbers ranging from 0 to 1, and δ is the oxygen non-stoichiometric number of values ranging from -0.1 to 0.5;which comprises the steps of mixing of solid phases of water-soluble salts of cations A, B, C and D with a water soluble anionic salt selected from the group comprising carbonate, bicarbonate, oxalate, sulfate, metaphosphate, phosphate, hydroxide, nitrite, chromate and dichromate; homogenization; addition of surfactant; stirring; suspension filtration, drying and calcination.;The present invention further relates to catalysts of perovskite structure and use thereof for high temperature decomposition of N2O.
