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 role of alkali metal promoters (Li, Na, K, Cs) in the c~ and/3 phases of NiMoO4 for butane oxidative dehydrogenation (ODH) was studied. The catalysts were characterized by BET, ICP, Xray fluorescence, AA, XRD, TG, DSC, IR, and XPS techniques. It was evidenced that the added alkali metals are dep
