Alkali metal halide-coated perovskite redox catalysts for anaerobic oxidative dehydrogenation of -butane.

Oxidative dehydrogenation (ODH) of -butane has the potential to efficiently produce butadiene without equilibrium limitation or coke formation. Despite extensive research efforts, single-pass butadiene yields are limited to <23% in conventional catalytic ODH with gaseous O. This article reports molten LiBr as an effective promoter to modify a redox-active perovskite oxide, i.
