    摘要： A filter such as a cigarette filter having a metal reagent which selectively binds with a gaseous component of a gas stream such as tobacco smoke. The metal reagent comprises nanometer or micrometer size clusters of a transition metal or alloy containing a transition metal. The transition metal can be incorporated in an intermetallic compound such as titanium aluminide or iron aluminide. The metal clusters can be incorporated in or on a support material such as silica gel, porous carbon or a zeolite. The metal reagent can remove the gaseous component by selectively binding to unsaturated hydrocarbons such as 1,3-butadiene. The binding can occur by insertion of a metal atom of the metal reagent into a C—H bond or a C—C bond of the gaseous component.

    摘要翻译： 一种过滤器，例如具有金属试剂的香烟过滤器，该金属试剂选择性地与气流的气体组分如烟草烟雾结合。 金属试剂包含含有过渡金属的过渡金属或合金的纳米或微米尺寸的簇。 过渡金属可以掺入金属间化合物如铝化铝或铝化铁。 金属簇可以并入载体材料中或其上，如硅胶，多孔碳或沸石。 金属试剂可以通过选择性地结合不饱和烃如1,3-丁二烯来除去气态组分。 结合可以通过将金属试剂的金属原子插入气态组分的C-H键或C-C键来进行。

    摘要： A cigarette filter having a reagent which chemically reacts with and removes a gaseous component of a smoke stream. The reagent contains functional groups covalently bonded to a non-volatile inorganic substrate which is incorporated in the filter. The filter can remove gaseous components such as aldehydes from tobacco smoke. Preferred functional groups are 3-aminopropylsilyl groups covalently bonded to silica gel (APS silica gel). The reagent can be contained in a space in the filter or incorporated in one or more filter elements such as tipping paper, shaped paper insert, mouthpiece plug, solid filter element, or free-flow filter element. The reagent can be part of or coated on paper such as tipping or filter paper or incorporated in non-paper filter elements formed from fibrous materials such as cellulose acetate or polypropylene fibers. Other preferred reagents include aminoethylaminopropylsilyl (AEAPS) silica gel and aminoethylaminoethylaminopropylsilyl (AEAEAPS) silica gel.
