Organic Sulfur Compound Patents (Class 502/168)
  • Patent number: 7906452
    Abstract: The invention relates to an ink for producing catalyst layers for electrochemical devices. The ink comprises catalyst material, ionomer material, water and at least one organic solvent. The organic solvent belongs to the class of tertiary alcohol's and/or the class of aliphatic diketones and bears functional groups which are stable to oxidative degradation in the ink. This prevents formation of decomposition products in the ink. The ink of the invention displays a high storage stability and is used for producing catalyst-coated substrates for electrochemical devices, in particular fuel cells (PEMFCs, DMFCs).

  • Patent number: 7867940
    Abstract: A method of preparing a supported catalyst includes dissolving a cation exchange polymer in alcohol to prepare a solution containing cation exchange polymer; mixing the cation exchange polymer containing solution with a catalytic metal precursor or a solution containing catalytic metal precursor; heating the mixture after adjusting its pH to a predetermined range; adding a reducing agent to the resultant and stirring the solution to reduce the catalytic metal precursor; mixing the resultant with a catalyst support; adding a precipitating agent to the resultant to form precipitates; and filtering and drying the precipitates. The method of preparing a supported catalyst can provide a highly dispersed supported catalyst containing catalytic metal particles with a reduced average size regardless of the type of catalyst support, which provides better catalytic activity than conventional catalysts at the same loading amount of catalytic metal.

  • Publication number: 20100286421
    Abstract: The present invention provides a novel glycerol-based heterogeneous solid acid catalyst by simultaneous partial carbonization and sulfonation of crude glycerol obtained as a by-product during the biodiesel process. Solid acid catalyst with similar activity is also prepared from glycerol pitch (by-product of fat splitting) and technical grade glycerol. These glycerol-based solid acid catalysts are employed for esterification of fatty acids and fatty acid present in the high and low free fatty acid (FFA) containing vegetable oils like rice bran, karanja and jatropha; fatty acid distillate; deodorizer distillate and acid oil which are being used as raw materials for the preparation of biodiesel. These catalysts are highly active, reusable and simplify the biodiesel process particularly for fatty acids or high FFA containing vegetable oils by replacing the traditional homogeneous mineral acid catalysts.

    Abstract: A membrane-electrode assembly in a polymer electrolyte/proton exchange membrane fuel cell includes the electrodes (anode and cathode), with a thin layer of catalyzed conductive support particles bonded to either side of the membrane. Where the polymer membrane comprises pendant chains of fluorinated carbon atoms with mobile proton containing terminal groups, proton conductivity with the catalyst particles is improved by chemically attaching like pendant chains to carbon atoms at surfaces of carbon particles. In certain implementations, an amino aryl perfluorinated sulfonic acid precursor is prepared. This precursor is converted to an aryl diazonium cation in the presence of carbon particles. The diazonium cation is reduced to the aryl radical which reacts with carbon atoms of the carbon substrate.

  • Patent number: 7632775
    Abstract: Disclosed are nanoparticles formed from a plurality of two or more different components. The two or more components are dispersed using a dispersing agent such that the nanoparticles have a substantially uniform distribution of the two or more components. The dispersing agents can be poly functional small organic molecules, polymers, or oligomers, or salts of these. The molecules of the dispersing agent bind to the particle atoms to overcome like-component attractions, thereby allowing different and/or dissimilar components to form heterogeneous nanoparticles. In one embodiment, dissimilar components such as iron and platinum are complexed using the dispersing agent to form substantially uniform heterogeneous nanoparticles. Methods are also disclosed for making the multicomponent nanoparticles. The methods include forming suspensions of two or more components complexed with the dispersing agent molecules. The suspensions can also be deposited on a support material and/or anchored to the support.
