摘要: Synergistic effect of FeVO₄ with α-Fe₂O₃ was found in Fe-V-O catalyst, which was responsible for the high apparent formation rate (A.F.R.) of benzaldehyde in liquid phase oxidation of toluene by hydrogen peroxide. The synergistic effect might create VO_x species as active sites; moreover, it improved the reducibility and the reactivity of Fe-V-O catalyst. In order to gain the high A.F.R. of benzaldehyde, the catalyst should have the moderate reducibility.
