A VMgO catalyst (containing 14 wt% vanadium) that is used in the oxidative dehydrogenation of propane (ODHP) reaction has been examined in detail by in situ EXAFS, in situ XRD and HREM. These characterisation techniques have revealed that, as prepared, the catalyst is in effect a three-component sys...
