• The effect of transition metal addition on the BiFe0.65Me0.05Mo oxide catalyst was studied in the oxidative dehydrogenation (ODH) of butenes.
• BiFe0.65Ni0.05Mo oxide catalyst shows excellent activity for the ODH reaction.
• The yield of butadiene (BD) is correlated with the facile oxygen mobility.
• 1-Butene is more favorable for producing BD than the 2-butenes.
BiFe0.65Me0.05Mo oxide catalysts promoted with different metals (Me = Ni, Co, Zn, Mn and Cu) were prepared and the effects of the transition metal addition based on multicomponent BiFeMo oxide catalysts have been investigated for the oxidative dehydrogenation of butenes to 1,3-butadiene. It has been found that the catalytic activity of BiFe0.65Me0.05Mo oxide catalysts depends on the nature of the metals employed, varying in the order of Ni > Co > Zn > Mn > Cu. Temperature-programed re-oxidation measurements revealed that the catalytic activity of the BiFe0.65Me0.05Mo oxide catalysts was well correlated with the oxygen mobility of the catalysts.
