SUPPORTED PD/C CATALYST AND THE PREPARATION METHODTHEREOF

摘要

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 R₁, R₂ or R₃ is independently selected from the group consists of H, CH₃, NH₂, OH and COOH.
