摘要: Provided are catalyst composites whose catalytic material is effective to substantially simultaneously oxidize carbon monoxide and hydrocarbons reduce nitrogen oxides. The have a two-metal layer on carrier, the comprising rhodium component supported by first support refractory metal oxide or ceria-zirconia composite; palladium second one more of promoter, stabilizer, binder; wherein amount total in equal greater than component. Methods making using same also provided.
