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
