  • Patent number: 6492298
    Abstract: An ordinary-temperature purifying catalyst includes an oxide having an oxygen defect introduced by a reduction treatment, and a noble metal loaded on the oxide. For example, the oxide can be at least one oxide selected from the group consisting of cerium oxides and zirconium oxides, at least a part of which has an oxygen defect. The catalyst can purify an environmental loading material, such as carbon monoxide, a nitrogen oxide, ethylene, formaldehyde, trimethylamine, methyl mercaptan and acetaldehyde, in air at an ordinary temperature. A method for how to use the catalyst is also disclosed.

  • Patent number: 6194650
    Abstract: A coated material comprising a substrate which has micropores and a reaction product coated thereon along the surface configuration of the substrate and an inner wall of the micropores thereof. The coated material is preferably produced by performing a supercritical coating step wherein a reaction precursor is dissolved in a supercritical fluid to form a precursor fluid and then the precursor fluid is brought into contact with a substrate in the presence with a reaction initiator to allow a reaction between the reaction precursor and the reaction initiator, thereby coating a reaction product onto the substrate.
