    Abstract: The exhaust gas purification catalyst disclosed herein is provided with a substrate 10 and a catalyst coating layer 30 that is formed on the surface of the substrate 10. The catalyst coating layer 30 is formed into a layered structure having upper and lower layers, with a lower layer 50 being closer to the surface of the substrate 10 and an upper layer 40 being relatively farther therefrom. The catalyst coating layer 30 is provided with Rh and Pd as precious metal catalysts and is provided with an OSC material having an oxygen storage capacity as a support. The Rh is disposed in the upper layer 40 of the catalyst coating layer 30, and the Pd is disposed in both the upper layer 40 and the lower layer 50 of the catalyst coating layer 30. At least a portion of the Pd in the upper layer 40 and in the lower layer 50 is supported on the OSC material. The mass ratio of the Pd disposed in the upper layer 40 to the Pd disposed in the lower layer 50 is not more than 0.4.

    Abstract: The invention pertains to a production process (2) of a solid catalyst material (7) using a solid material (8), having at least one pore or at least one cavity, the pore or the cavity having one diameter of less than 1 µm, which is exposed to a metal complex (15, 15') entering the pore or cavity, wherein the solid material (8, 8') is impregnated with metal by steps of adsorption of the metal complex (15, 15') in the pore or in the cavity of the solid material (8, 8'), and decomposition of the metal complex (15, 15') by means of oxidation, wherein metal from the metal complex (15, 15') is attached to a surface of the solid material (8, 8'). The metal is bond to the surface of the solid material (8, 8') at least in part along the pore or the cavity. At least some of the structures enclosing the pore or the cavity bind metal dispersed as monomeric species or dimeric species of metal or metal bound to the oxidizing gas (17, 17'), whereby all monomeric species exceed all oligomeric species by number. Further, the invention relates to an apparatus for production of a solid catalyst material (7).
