1. A supported catalyst used for synthesizing polyether amine, comprising:
a carrier;
active components, which are Ni, Cu and Mo; and
a cocatalyst, which is CeO2, wherein
based on the total weight of the supported catalyst, the content of Ni is 2%-15%, the content of Cu is 1%-5%, the content of Mo is 0.1%-0.6%, the content of Ce in CeO2 is 1%-8%, and the total supported amount of the active components is not less than 10%; and
wherein the carrier is γ-alumina, amorphous silica, titanium dioxide, or magnesium-aluminum composite oxide.
