  • Patent number: 7737078
    Abstract: The formation of H2S in a stoichiometric or reducing atmosphere is restrained without using Ni or Cu as an environmental load substance. An additional oxide composed of an oxide of at least one kind of metal selected from the group consisting of Bi, Sn and Zn was added to a three-way catalyst for purifying an exhaust gas emitted from an internal combustion engine of which the combustion is controlled in near a stoichiometric atmosphere in the amount of from 0.02 mol to 0.2 mol per liter of the catalyst. The additional oxide forms SO3 or SO4 from SO2 in an oxidizing atmosphere, and stores sulfur components as a sulfide in a reducing atmosphere so that emission of H2S can be restrained. And since no environmental load substance is contained, the catalyst can be used safely.

  • Publication number: 20100075827
    Abstract: A nanoporous catalytic membrane which displays several unique features Including pores which can go through the entire thickness of the membrane. The membrane has a higher catalytic and product selectivity than conventional catalysts. Anodic aluminum oxide (AAO) membranes serve as the catalyst substrate. This substrate is then subjected to Atomic Layer Deposition (ALD), which allows the controlled narrowing of the pores from 40 nm to 10 nm in the substrate by deposition of a preparatory material. Subsequent deposition of a catalytic layer on the inner surfaces of the pores reduces pore sizes to less than 10 nm and allows for a higher degree of reaction selectivity. The small pore sizes allow control over which molecules enter the pores, and the flow-through feature can allow for partial oxidation of reactant species as opposed to complete oxidation. A nanoporous separation membrane, produced by ALD is also provided for use in gaseous and liquid separations.
