摘要
Bifunctional catalysts MoO/VO-CD-T(CD: calcined dolomite and T: calcined temperature) with both basic sites and redox sites were prepared by impregnation method. The results showed that the molybdenum/vanadium oxides on the catalyst surface were mainly composed of MoO3 and V2O5, and the formation of different phases between calcined dolomite and molybdenum/vanadium oxides could adjust the stability and redox performance of the catalyst. The allyl alcohol was more favorable to be formed over the VO-CD-500 catalyst in air atmosphere, mainly because the oxygen in air could inhibit the reduction of high-valence vanadium. The MoO-CD-500 catalyst had a low activity to allyl alcohol because the reducibility of Mo6+ was weak. 2% VO-CD-500 catalyst showed the best catalytic performance under the condition of 20% glycerol solution and reaction temperature of 320 ℃, with a glycerol conversion of 52.4% and a selectivity to allyl alcohol of 37.4%. © 2023 Zhejiang University.
