摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas purifying method capable of sufficiently removing a nitrogen oxide in exhaust gas at a high standard.
SOLUTION: An exhaust gas purifying catalyst is used including a first catalyst particle having a first porous carrier carrying at least one kind of a first noble metal selected from platinum and palladium, rhodium, and a nitrogen oxide occlusion material with a carrying rate of the first noble metal at 0.3-2.0 part by mass with respect to 1 part by mass rhodium, and a second catalyst particle having a second porous carrier carrying at least one kind of a second noble metal selected from platinum and palladium, and a nitrogen oxide occlusion material where rhodium is substantially not carried by the second porous carrier. The nitrogen oxide in the exhaust gas is removed by bringing the exhaust gas in contact with the exhaust gas purifying catalyst while alternately repeating steps of making the air-fuel ratio of the exhaust gas brought in contact with the exhaust gas purifying catalyst into a fuel lean state, and making the air-fuel ratio into a fuel rich state.
