  • Supporting for an exhaust gas purification catalyst and production method
    Publication number: 20080220163
    Abstract: A metal oxide is synthesized in the pores of a porous catalyst base material by impregnating a raw material solution for synthesis of that metal oxide into those pores. At that time, mesh-like cracks are formed in the metal oxide support layer coated onto the inner surfaces of the pores by adjusting the solid portion concentration in the raw material solution for synthesizing the metal oxide to a suitable value. In addition, fine pores are formed in the metal oxide support layer obtained after firing by containing a polymer and so forth in the raw material solution for synthesizing the metal oxide. The presence of these mesh-like cracks and/or fine pores in the metal oxide support layer allow the obtaining of effects such as greater ease of diffusion of exhaust gas into this support layer.

  • Method for production of exhaust gas purifying catalyst
    Patent number: 6622382
    Abstract: A catalytically active component is deposited exclusively on a carrier component by utilizing a container-integrated carrier. Prior to the deposition of the active component on the carrier, the carrier is sealed and then the deposition of the active component is performed.
    Type: Grant
