A critical assessment of the published data on vanadium phosphorus oxide catalysts is presented. Aspects that are included for discussion include (i,l the nature of the bulk phases present in the active unpromoted catalysts, (ii) the nature of the surface of the active unpromoted catalysts and W the
The oxidative dehydrogenation of n-butane to butenes over iron-zinc oxide catalysts was etudied. Xray diffraction (XRD), temperature-programmed reduction (TPR) and Mt%sbauer spectroscopy were used to try to identify the catalytically active phase. It was found that the presence of a zinc ferrite (Z&
