Abstract: Disclosed are to a supported catalyst used for synthesizing polyether amine, and a preparation method and use thereof. The supported catalyst introduces Mo and CeO2 into Ni and Cu active components. By means of the cooperation of Ni, Cu and Mo, CeO2 and Ni form more active sites, such that the supported catalyst can have high reaction activity and selectivity. By using the supported catalyst to synthesize polyether amine, the amination efficiency and selectivity of polyether polyol can be greatly enhanced, thereby preparing the polyether amine with light color and narrow molecular weight distribution. In addition, the cost of the catalyst can be reduced, a process condition is relatively mild, and the disadvantage of low reaction activity of a nickel-based catalyst in synthesizing small molecule polyether amine can be overcome, such that the supported catalyst has a desirable industrial application prospect.
