Abstract
Multicomponent bismuth molybdate (M II 9Fe 3Bi 1Mo 12O 51) catalysts with different divalent metal (M II = Mg, Mn, Co, Ni, and Zn) were prepared by a co-precipitation method, and were applied to the oxidative dehydrogenation of n-butene to 1,3-butadiene. Effect of divalent metal (M II) on the catalytic performance of M II 9Fe 3Bi 1Mo 12O 51 catalysts was investigated. X-ray photoelectron spectroscopy (XPS) measurements were conducted to determine the oxygen mobility of M II 9Fe 3Bi 1Mo 12O 51 catalysts. It was found that the catalytic performance of M II 9Fe 3Bi 1Mo 12O 51 catalysts was closely related to the oxygen mobility of the catalysts. The yield for 1,3-butadiene was monotonically increased with increasing oxygen mobility of the catalysts. Among the catalysts tested, the Co 9Fe 3Bi 1Mo 12O 51 catalyst with the highest oxygen mobility showed the best catalytic performance in the oxidative dehydrogenation of n-butene.
