    摘要： A method of making palladium-containing nanoscale catalyst particles comprising subjecting a starting material to laser energy so as to form a vapor and condensing the vapor so as to form the catalyst particles. The catalyst comprises nanoscale particles of palladium and/or palladium oxide incorporated in and/or on nanoscale particles of a metal or metal oxide. The nanoscale catalyst, which can be incorporated in the tobacco cut filler, cigarette wrapper and/or cigarette filter of a cigarette, is useful for low-temperature and near-ambient temperature catalysis. The nanoscale catalyst can convert carbon monoxide and nitric oxide that are found in mainstream smoke to carbon dioxide and nitrogen, respectively. The nanoscale catalyst may also be incorporated into a hydrocarbon conversion reactor, into a vehicle exhaust emissions system, into a laser, into a fuel cell or used in an air filter or for emissions reduction in the cold starting of an automobile engine.

    摘要： A metallo-organic decomposition process for the preparation of intermetallic powders and films. A liquid mixture containing a first metal precursor and a second metal is heated to a temperature in a first temperature range so as to convert the first metal precursor to a first metal followed by heating to a temperature in a second temperature range so as to form an intermetallic compound by a solid state reaction between the first and second metals. The intermetallic compound can be used as a catalyst in cut filler and/or the filter of a cigarette.

    摘要： A carbonaceous heat source comprising metal oxides and methods for making such heat source are provided. The heat source has an ignition temperature substantially lower than conventional carbonaceous heat sources, while at the same time produces virtually no carbon monoxide upon combustion. The heat source is prepared by pre-forming the carbon and binder materials into a desired shape, and then treating the shape with a sol containing metal oxide precursors. The metal oxide precursors are deposited in the pre-formed carbon shape. Further treatment converts the deposited metal oxide precursors into metal oxide.
