A catalyst useful for the production of olefins from alkanes via oxidative dehydrogenation (ODH) is disclosed. In accordance with a preferred embodiment of the present invention, a catalyst for use in ODH processes includes a base metal, a promoter metal, and a support comprising a plurality of discrete structures. A base metal is herein defined as a non-Group VIII metal, with the exception of iron, cobalt and nickel. Suitable base metals include Group IB-VIIB metals, Group IIIA-VA metals, Lanthanide metals, iron, cobalt and nickel. Suitable promoter metals include Group VIII metals (i.e. platinum, palladium, ruthenium, rhodium, osmium, and iridium). In some embodiments the support is fabricated from a refractory material. Suitable refractory support materials include alumina, stabilized aluminas, zirconia, stabilized zirconias (PSZ), titania, yttria, silica, niobia, and vanadia.
