Abstract
The present disclosure provides a method for producing an exhaust gas purifying catalyst, in which fine Rh—Pd particles exhibiting high catalytic activity are produced such that a variation in the Pd composition can be reduced. The present disclosure relates to a method for producing an exhaust gas purifying catalyst having fine composite metal particles containing Rh and Pd, comprising: preparing a starting material solution containing Rh and Pd, in which the atomic percentage of Pd to the total of Rh and Pd is 1 atomic % to 15 atomic %; and allowing the prepared starting material solution to react with a neutralizer by a super agitation reactor having a rotation number of 500 rpm or more, to generate fine composite metal particles.
