ABSTRACT:
A catalyst composition for purification of exhaust gas, including (a) high-silica zeolite having a Si/Al ratio of 40 or more, subjected to ion exchange with at least one metal selected from Pt, Pd, Rh, Ir and Ru, and (b) a heat-resistant oxide containing at least one metal selected from Pt, Pd, Rh, Ir and Ru; a catalyst for purification of exhaust gas, including a monolith carrier and the catalyst composition supported on the carrier; and a process for producing the catalyst. The catalyst has high activity for exhaust gas purification even when the catalyst contains Rh--, --, which is an expensive catalyst component, in a very small amount.
