  • Sulfur-containing organic compound assisted metal nanoparticle synthesis for three-way catalysis application
    Patent number: 11786885
    Abstract: A method of manufacturing a catalyst article, the method comprising: providing a slurry comprising a support material, palladium ions, alkaline-earth-metal ions and an organic compound, wherein the organic compound comprises a functional group selected from a sulfo group (—SO3H), a sulfonyl group (—S(?O)2—) and a sulfinyl group (—S(?O)—); disposing the slurry on a substrate; and heating the slurry to form nanoparticles of the palladium and nanoparticles of a sulfate of the alkaline earth metal on the support material.
    Type: Grant
