Abstract
Iron phosphate catalysts possess a unique selectivity to oxidative dehydrogenation. Unlike catalysts consisting of molybdenum and/or vanadium, they have no double-bond oxygen species (M=O), which are considered to be responsible for the oxygen insertion function and, as a result, for the degradation by C–C bond fission. The defect of iron phosphate catalysts is their lack of oxidation activity. The addition of a very small amount of molybdenum to iron phosphate markedly enhances the oxidation activity without modifying the high selectivity that originates from iron phosphate.
