    摘要: A composite base metal oxide catalyst of improved high temperature stability is provided by prereacting a selected base metal oxide catalyst or its precursor compounds with a selected refractory high-surface-area spinel or its precursor compounds to form a crystalline solid solution of the catalyst and the spinel. This solid solution has the properties of good catalytic activity and high temperature structural and surface area stability. An example of such a composite catalyst is CuCr2O4 in solid solution with NiAl2O4.
