    • Cut filler compositions, smoking articles such as cigarettes 2, methods for making cigarettes and methods for treating cigarette smoke are provided, which involve the use of metal-containing nanowires. The metal-containing nanowires are capable of removing at least one constituent from tobacco smoke, preferably in a selective manner. The metal-containing nanowires may comprise any suitable metal, metal oxide or mixtures thereof. For example, the metal-containing nanowires comprise at least one transition or lanthanide metal or metal oxide thereof. Exemplary metals or metal oxides thereof include, but are not limited to, iron, copper, zinc, titanium, vanadium, palladium, cobalt, molybdenum and manganese. The metal-containing nanowires may be produced by (i) loading at least one metal-containing composition into a mesoporous molecular sieve substrate via repeated incipient-wetness impregnation followed by stepwise calcination to form said nanowires; and (ii) isolating the nanowires by extracting the mesoporous molecular sieve substrate, e.g., with aqueous NaOH.
    • 提供切割填料组合物,吸烟制品如香烟2,制造香烟的方法和处理香烟烟雾的方法,其涉及使用含金属的纳米线。 含金属的纳米线能够优选以选择性方式从烟草烟雾中除去至少一种成分。 含金属的纳米线可以包含任何合适的金属,金属氧化物或其混合物。 例如,含金属的纳米线包含至少一种过渡金属或镧系元素金属或其金属氧化物。 示例性的金属或金属氧化物包括但不限于铁,铜,锌,钛,钒,钯,钴,钼和锰。 含金属的纳米线可以通过以下方法来制备:(i)通过重复的初始湿润浸渍将至少一种含金属的组合物装载到介孔分子筛基材中,然后逐步煅烧以形成所述纳米线; 和(ii)通过例如用NaOH水溶液萃取介孔分子筛底物来分离纳米线。
