1. A method of preparing a catalyst composition comprising
providing a mixture comprising alumina, water, and an oxidative dehydrogenation catalyst precursor comprising a mixed metal oxide having the empirical formula:
Mo1.0V0.12-0.49Te0.05-0.25Nb0.10-0.20Od
heating the mixture comprising the oxidative dehydrogenation catalyst precursor, the alumina, and the water to remove at least 40 wt. % of the water to provide a pre-calcination catalyst composition, and
calcining the pre-calcination catalyst composition to provide the catalyst composition having the empirical formula:
Mo1.0V0.12-0.49Te0.05-0.25Nb0.10-0.20Al0.01-2.0Od
wherein d is a number to satisfy the valence of the oxide, wherein the catalyst composition is from 60 wt. % to 80 wt. % amorphous.
