  • Patent number: 10167562
    Abstract: A catalyst for an oxygen evolution reaction has a higher and longer-life catalytic activity than that of the conventional and expensive noble metal oxide catalysts, such as RuO2 and IrO2. An A-site ordered perovskite oxide catalyst (such as CaCu3Fe4O12 and CaMn3Mn4O12 etc.) as an oxygen evolution reaction catalyst is excellent in cost effectiveness. The catalyst has a high catalytic activity compared with a noble metal oxide catalyst, and a long repetition use life since it is extremely stable also under the oxidative reaction conditions. Use of the catalyst is expected to the important energy conversion reactions such as a charge reaction of a metal-air battery, an anode oxygen evolution reaction in the case of a direct water decomposition reaction by sunlight, etc.

  • Patent number: 9255537
    Abstract: A palladium-only (i.e., platinum free) oxidation catalyst body is used to oxidize carbon monoxide and hydrocarbons in the exhaust stream of a diesel engine powered vehicle, which is operated at a fuel-lean air-to-fuel ratio (A/F) for much of the time it powers a vehicle. Periodically, a recent history of the temperatures of the exhaust gas at the inlet to the palladium oxidation catalyst body is prepared in a computer control module. And a recent history of the A/F of the operating engine is considered. These temperature and A/F values are then used in determining whether the engine should be temporarily operated in a fuel-rich or stoichiometric A/F mode to provide an exhaust gas composition suitable for rejuvenation of the palladium by reducing its oxide formed during lean operation of the engine.

  • Patent number: 9216409
    Abstract: Variations of bulk powder catalyst material including Cu—Mn, Cu—Fe, and Fe—Mn spinel systems for ZPGM TWC applications are disclosed. The disclosed bulk powder catalyst samples include stoichiometric and non-stoichiometric Cu—Mn, Cu—Fe, and Fe—Mn spinels on Pr6O11—ZrO2 support oxide, prepared using incipient wetness method. Activity measurements under isothermal steady state sweep test condition may be performed under rich to lean condition. Catalytic activity of samples may be compared to analyze the influence that different binary spinel system bulk powders may have on TWC performance of ZPGM materials for a plurality of TWC applications. Stoichiometric Cu—Mn, Cu—Fe, and Fe—Mn spinel systems exhibit higher catalytic activity than non-stoichiometric Cu—Mn, Cu—Fe, and Fe—Mn spinel systems. The influence of prepared Cu—Mn, Cu—Fe, and Fe—Mn spinel systems may lead into cost effective manufacturing solutions for ZPGM TWC systems.

  • Patent number: 9121325
    Abstract: In an internal combustion engine, inside of an engine exhaust passage, a hydrocarbon feed valve (15) and an exhaust purification catalyst (13) are arranged. The concentration of hydrocarbons which flows into the exhaust purification catalyst (13) is made to vibrate by within a predetermined range of amplitude of a 200 ppm or more and within a predetermined range of period of 5 second or less, whereby the NOx which is contained in exhaust gas is reduced at the exhaust purification catalyst (13). At this time, the nitrogen-containing intermediate which is produced in the NOx reduction process is exhausted from the exhaust purification catalyst (13). An intermediate purification catalyst (14) for removal of the exhausted nitrogen-containing intermediate is arranged downstream of the exhaust purification catalyst (13).

  • Publication number: 20150148218
    Abstract: Rapid, reversible redox activity may be accomplished at significantly reduced temperatures, as low as about 200° C., from epitaxially stabilized, oxygen vacancy ordered SrCoO2.5 and thermodynamically unfavorable perovskite SrCoO3-?. The fast, low temperature redox activity in SrCoO3-? may be attributed to a small Gibbs free energy difference between the two topotactic phases. Epitaxially stabilized thin films of strontium cobaltite provide a catalyst adapted to rapidly transition between oxidation states at substantially low temperatures. Methods of transitioning a strontium cobaltite catalyst from a first oxidation state to a second oxidation state are described.
