The invention provides an activated carbon loaded compound metal catalyst, a preparation method and application thereof. The catalyst is prepared from a carrier, an active ingredient and an auxiliary, wherein the carrier is activated carbon, the active ingredient is at least one of platinum, palladium and rhodium, and the auxiliary is at least one of iron, zinc, cobalt and copper. The catalyst can be applied to a reaction for synthesizing a corresponding amine compound by catalytic hydrogenation, and has high catalytic activity and high hydrogenation speed, the reduction process is effectively promoted by the using method, and a nitro group influenced by power supply group can be quickly reduced into amino by 100 percent. The catalyst is mild in conditions, good in stability and more in using times in the circular using process.
