The catalyst for preparing chlorine by oxidation of hydrogen chloride and preparation thereof are provided. The catalyst includes carrier and active components, wherein the active components, based on the total weight of the catalyst, are as follows : 1-20wt% of copper, 0.01-5wt% of boron, 0.1-10wt% of alkaline metal elements, 0.1-15wt% of one or more of rare earth elements, 0-10wt% of one or more elements selected from the group consisting of magnesium, calcium, barium, manganese, iron, nickel, cobalt, zinc, ruthenium and titanium. The catalyst can be prepared by two-step impregnation. The catalyst can obviously improve conversion rate and stabilization as compared with existing similar catalysts.
