An oxide catalyst for use in an oxidation reaction of an olefin and/or an alcohol, the oxide catalyst comprising: the oxide catalyst contains molybdenum, bismuth, iron, cobalt, and cerium; an atomic ratio a of bismuth to 12 atoms of molybdenum is 2≤a≤_6, an atomic ratio b of iron to 12 atoms of molybdenum is 2.5
Abstract:
A bulk metal oxide catalyst can be prepared by combining metal oxide powders or oxide-producing species and reacting selected ingredients prior to their inclusion in the formulation of the catalyst. Mixed metal oxide phases can be designed and prepared for use as an ingredient for a bulk metal oxide catalyst to alter properties for catalytic performance or physical properties that would not be obtained using mixtures of singular metal oxide ingredients.
