Abstract
Supported perovskite-type oxides are described. The perovskite-type oxides have the general formula of AA'BB′O, wherein A is an ion of a metal of Group IIIa or IIIb of the periodic table of elements or mixtures thereof; A′ is an ion of a metal of Groups Ia or IIa of the periodic table or mixtures thereof; B and B′ are ions of a d-block transition metal of the periodic table or mixtures thereof; x, x′, y and y′ vary from 0 to 1; 0.95<x+x′<1.05; 0.95<y+y′<1.05; δ is the deviation from ideal oxygen stoichiometry. This invention also provides for the selection of support materials and the shapes of supported perovskite-type oxides as well as the methods for making them.
