Catalyst for exhaust gas purification and process for producing the same |
| abstract |
Noble-metal particles (30,30...) are deposited on an oxygen-adsorbing/releasing material (20) having the ability to adsorb and release oxygen, and the surface of the oxygen-adsorbing/releasing material (20) is coated with a coating layer (40) comprising a sulfate compound of a metallic element contained in the oxygen-adsorbing/releasing material (20). Thus, a catalyst (1) for exhaust gas purification is obtained. The catalyst (1) for exhaust gas purification thus obtained can prevent the oxygen-adsorbing/releasing material (20) from reacting with a sulfur matter contained in an exhaust gas and forming a new sulfate compound on the surface of the oxygen-adsorbing/releasing material (20). This in turn can prevent the hydrogen sulfide concentration in the exhaust gas from temporarily increasing due to the sulfur matter which has been adsorbed on the surface of the oxygen-adsorbing/releasing material from the exhaust gas. |
