Abstract
A catalyst for oxidative dehydrogenation of organic compounds is provided by forming a solution of catalyst precursor components comprised of Feand Zncations and at least one other modifier element cation in water to form an aqueous solution of the catalyst precursor components. The modifier element cation has a standard reduction potential of from greater than about −2.87 E° (V) to less than about −0.036 E° (V) with a valence of +2. A base is separately and simultaneously added to the aqueous solution in amounts to maintain the pH of the aqueous solution at a pH of from about 8.5 to about 9.5 as the catalyst precursor components. The catalyst precursor components are allowed to react and precipitate out of solution as a precipitate. The resulting precipitate is calcined to form a modified zinc ferrite catalyst compound.
