Abstract:

Multicomponent bismuth molybdates were prepared by a co-precipitation method for use in the oxidative dehydrogenation of n-butene to 1,3-butadiene. The effect of divalent and trivalent metals on the catalytic performance of multicomponent bismuth molybdate catalysts was investigated. It was found that the metal ratio of Fe/Bi/Mo = 3:1:12 was favorable for the reaction. The successful formation of Ni_XCo_8−XFe₃Bi₁Mo₁₂O₅₀ (X = 0-8) catalysts was well confirmed by XRD and ICP-AES measurements. The multicomponent bismuth molybdate catalysts showed a better catalytic performance than the pure γ-Bi₂MoO₆ catalyst. Among the Ni_XCo_8-XFe₃Bi₁Mo₁₂O₅₀ (X = 0-8) catalysts, Ni₃Co₅Fe₃Bi₁Mo₁₂O₅₀ showed the highest yield of 1,3-butadiene.
