  • Patent number: 7238639
    Abstract: An oxygen storage material based on cerium oxide with at least one other oxide of the metals silicon and zirconium, wherein the cerium oxide and the other oxides are present in the form of a mixed oxide. The material is obtainable in that hydroxidic precursors of the mixed oxide are first prepared in a manner known per se using a wet-chemical route, these precursors are optionally dried at temperatures between 80 and 300° C. and the dried precursors are then treated under a hydrogen-containing atmosphere at a temperature between 600 and 900° C. for a period of 1 to 10 hours. The reductive thermal treatment endows the material with a greatly improved dynamic behavior as compared with conventional calcination in air.

  • Patent number: 7201888
    Abstract: The present invention provides silver oxide particles having an average diameter of less than or equal to 100 nm that are stable and can be transported in dry powder form. The surface of the silver oxide particles is coated with an extremely thin layer of a surfactant such as fatty acid. Nanosized silver oxide particles according to the invention are preferably formed via the addition of a strong base to a mixture including an aqueous silver salt solution and a surfactant dissolved in an organic solvent that is at least partially water miscible. The strong base causes silver oxide to precipitate from the mixture as nanosized particles, which are immediately encapsulated by the surfactant and thus protected from further crystal growth and Ostwald ripening. The nanosized surfactant coated particles of silver oxide can be washed and dried and then transported in dry form.

  • Patent number: 7132584
    Abstract: A method of using high temperature plasma to disintegrate waste containing titanyl phthalocyanine (TiOPc) comprises heating a mixture of titanyl phthalocyanine (TiOPc), a vitrifying material and optionally selected waste soil to a temperature of 1,220° C. to 10,000° C. until the mixture becomes a molten lava. The plasma breaks down the titanyl phthalocyanine and encapsulates the benign products in the lava that is chemically very stable. Since the titanyl phthalocyanine (TiOPc) is disintegrated completely in the process, the titanyl phtbalocyanine (TiOPc) no longer represents a threat to the environmental.

  • Patent number: 7129193
    Abstract: This invention aims at providing a catalyst body exhibiting a lower degradation of a catalyst due to thermal durability and capable of keeping higher catalyst performance for a long time. A catalyst component such as Pt is directly supported by Zr, W, etc, replacing elements inside a support such as Al of cordierite to provide a catalyst body without forming a coating layer. A combination of the catalyst component and the element inside the support is selected so that support strength is greater than 5 eV by simulation using a density functional method. Coarsening of catalyst particles can be suppressed and a high-performance catalyst body excellent in thermal durability can be obtained.

  • Patent number: 7125534
    Abstract: Single-walled carbon nanotubes have been synthesized by the catalytic decomposition of both carbon monoxide and ethylene over a supported metal catalyst known to produce larger multi-walled nanotubes. Under certain conditions, there is no termination of nanotube growth, and production appears to be limited only by the diffusion of reactant gas through the product nanotube mat that covers the catalyst. The present invention concerns a catalyst-substrate system which promotes the growth of nanotubes that are predominantly single-walled tubes in a specific size range, rather than the large irregular-sized multi-walled carbon fibrils that are known to grow from supported catalysts.
