Transition Metal Oxides And Oxoions
Most industrially desirable oxidation processes target products of partial, not total oxidation. Well-investigated examples are the oxidation of propane or propene to acrolein, butane to maleic acid anhydride, benzene to phenol, or the ammoxidation of propene to acrylonitrile. The mechanism of many reactions of this type is adequately described in terms of the Mars and van Krevelen model31 A molecule is chemisorbed at the surface of the oxide and reacts with one or more oxygen ions, lowering...
