Abstract

PURPOSE:To provide a durable ternary catalyst exhibiting exhaust gas treating power regardless of sharp fluctuations in exhaust gas components by supporting a Ce component on activated alumina followed by calcination and support of Rh or Rh and one or more kinds of other platinum group metals. CONSTITUTION:Activated alumina carrier is impregnated with a 0.01-1.0 mol/l aq. soln. of a Ce cpd. such as Ce(NO3)3 and calcined at above 600 deg.C, esp. above 1000 deg.C. The amt. of Ce supported is 0.01-1.0 mol per liter of carrier. The Ce- supported carrier is then impregnated with an aq. soln. of Rh salt or Rh and other platinum group metal salts and calcined at above 600 deg.C to prepare a desired exhaust gas cleaning catalyst. It is desirable to support 0.1 g of Rh and above 0.2 g of other platinum group metals to 1 l of the carrier.
