Exhaust gas purifying catalyst

The invention discloses a catalyst for purifying exhaust gas apparatus having a Three-way Catalyst (TWC) superior in purification performance of, particularly, NOx, among carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx), in exhaust gas discharged from a gasoline automobile. It is provided by a catalyst for purifying exhaust gas containing a Rhodium (Rh)-loaded porous inorganic oxide and barium sulfate (BaSO4), with loaded or not-loaded onto alumina. At least a part of Rh is present independently from Ba inside a catalyst layer, and Rh-Ba deviation rate determined from EPMA analysis is 10% to 80%. It is preferable that loaded amount of Rhodium is 0.05 g/L to 2.0 g/L, and amount of barium sulfate is 0.5 g/L to 25 g/L and 0.5 g/L to 15 g/L, in the case of being loaded or not-loaded onto alumina, respectively.
