A supported Pd/C catalyst, wherein the Pd supported to the active carbon carrier is present in the microcrystalline state, and the microcrystallines whose diameters are less than 2.5nm take up more than 80wt% of the total amount of the Pd microcrystallines. The preparation method of the supported Pd/C catalyst, wherein the solution for impregnating or spraying the active carbon carrier contains Pd compound and compound with formula I, wherein n, m or l is independently selected from the integers of 0 and 1~5, and R<SUB>1</SUB>, R<SUB>2</SUB> or R<SUB>3</SUB> is independently selected from the group consists of H, CH<SUB>3</SUB>, NH<SUB>2</SUB>, OH and COOH. |
