ABSTRACT:
An exhaust gas purifying catalyst wherein the catalytic activity can be recovered over a wide temperature range is provided. Also provided are a method for recovering an exhaust gas purifying catalyst, and a catalyst system for exhaust gas purification. The exhaust gas purifying catalyst is characterized by containing an oxide A containing an oxide (A-1) containing an alkaline earth metal and/or a rare earth metal and an inorganic oxide (A-2), and a noble metal B supported by the oxide A. This exhaust gas purifying catalyst is also characterized in that the weight ratio of the oxide (A-1) containing an alkaline earth metal and/or a rare earth metal to the noble metal B is from 1:10 to 1:500.
