“…Similar trends were also found when using cesium-doped nickel molybdates for catalyzing n-butane ODH (46). When increasing the Cs load (from 0 to 6%-surface atomic ratio Cs/Mo), the TPR data showed a simultaneous decrease in the reducibility of the catalysts, evidenced by an increase in the temperature of onset of reduction.…”

“…The number of papers found for V}Mg}O catalysts is particularly noteworthy (see Table 1), these catalysts being used by several researchers, including Kung and coworkers. Nickel molybdate catalysts also have been investigated extensively, by the present authors too (38)(39)(40)(41)(42)(43)(44)(45)(46)(47). Concerning the best performances obtained, both vanadium-and nickel-containing oxides must be distinguished, as mentioned below.…”

“…Catalysts with higher basic sites favor 1-butene formation and its subsequent dehydrogenation to butadiene, while catalysts with acidic character resulted in a high content of initial 2-butenes, which further give carbon oxides through a series of reactions. This also agrees with the findings of Chaar et al, Harding et al, and Madeira et al…”
