Abstract
PURPOSE: To obtain a catalyst for cleaning exhaust gas containing rhodium high in activity and durability with a small quantity on the carrier by using heat-treated crystal of rhodium nitrate and a compound of platinum group elements supported by the carrier.
CONSTITUTION: As a catalyst for cleaning exhaust gas of automobiles and general industries, a crystal of rhodium nitrate is heat-treated to produce a complex compound of rhodium nitrate and rhodium oxide expressed by Rh(NO3)xOy. Then, this complex compound and compound of platinum group metal are dissolved in aqueous solution and infiltrated into an inorganic porous substance such as activated alumina carrier, etc. to burn the resulting product. This catalyst can be easily manufactured industrially, and high in activity and durability with a small carried quantity.
