The invention discloses an ammonia water pretreated activated carbon supported ternary metal catalyst and application thereof, ammonia water pretreated activated carbon is used as a carrier, and noble metal elements, transition metal elements and auxiliary alkaline earth metal elements are supported on the carrier. Wherein the noble metal element is selected from W, Re and Ru, the transition metal element is selected from Nb, In and Pb, and the alkaline earth metal element is selected from Ba, Ca and Sr. The method is applied to preparation of cyclopentanol through catalytic hydrogenation of cyclopentanone, the selectivity of the product cyclopentanol can reach 100% while the conversion rate of cyclopentanone reaches 100%, the separation and purification burden of the product can be greatly relieved, and the production cost is reduced; the catalytic reaction process is low in operation temperature, free of solvents, green and low in energy consumption; the catalyst has high activity, the reaction time is shor
