PURPOSE: An oxidation catalyst for emission control of dioxin in exhaust gas is provided, which can oxidation remove 1,2-dichlorobezene(DCB), is not poisoned by sulfur, can oxidize CB and CP, a precursor and an intermediate of dioxin and also can remove nitrogen oxides. CONSTITUTION: The oxidation catalyst is manufactured as follows: (i) immobilize 0.001-20 wt.% of one or more metals selected from the group consists of Mn, Ce, Co. Fe and V on the surface of carriers such as Al2O3, TiO2, ZrO2, CeO2, Mn and SiO2; (ii) dry at 100-120 deg.C and calcine at an air environment of 300-500 deg.C for 12-24 hours; and (iii) impregnate the calcined catalyst to a ruthenium solution for supporting 0.001-8 wt.% of ruthenium on the photocatalyst before drying at 100-120 deg.C followed by calcination at an air environment of 300-500 deg.C for 12-24 hours.
