| description | A method of preparing a catalyst support structure for use in a catalytic reaction. According to the method, a mixed metal oxide compound which defines a crystal lattice is synthesized. Cations of at least one catalytic promoter element are dispersed within the compound and incorporated into the crystal lattice. The conditions of synthesis are preselected to inhibit destabilization of the catalyst support structure such that the structure remains stable against collapse and exsolution under reaction conditions associated with the catalytic reaction. The metal oxide compound may comprise an oxidic perovskite having the formula A(1-x)A′(x)B(1-y)B′yO3 wherein A and B represent metal cations and A′ and B′ represent cations of the promoter element or elements. Also provided is a catalyst support structure having cations of a promoter element incorporated into its crystal lattice. The support structure is stable against collapse and exsolution under reaction conditions. |
