Disclosed is an exhaust gas purifying catalyst that can be rapidly regenerated at low temperatures against SOx poisoning that can be used as a catalyst for purifying exhaust gas from automobiles, factories, and the like. An exhaust gas purifying catalyst that removes NOx in exhaust gas and that contains a complex oxide catalyst of the general formula: BaB x O y is used as an exhaust gas purifying catalyst. However, the B component is at least one of the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Ce, Zr and W, 0 <x ≦ 1, 1 ≦ y ≦ 4 To do. [Selection] Figure 3 |
