  • Patent number: 9776140
    Abstract: A process for making an iron oxide impregnated carbon nanotube membrane. In this template-free and binder-free process, iron oxide nanoparticles are homogeneously dispersed onto the surface of carbon nanotubes by wet impregnation. The amount of iron oxide nanoparticles loaded on the carbon nanotubes range from 0.25-80% by weight per total weight of the doped carbon nanotubes. The iron oxide doped carbon nanotubes are then pressed to form a carbon nanotube disc which is then sintered at high temperatures to form a mixed matrix membrane of iron oxide nanoparticles homogeneously dispersed across a carbon nanotube matrix. Methods of characterizing porosity, hydrophilicity and fouling potential of the carbon nanotube membrane are also described.

  • Patent number: 6782892
    Abstract: Cut filler compositions, cigarettes, methods for making cigarettes and methods for smoking cigarettes which involve the use of manganese oxide mixtures that include nanoparticle manganese oxide and other nanoparticle additive(s) capable of converting carbon monoxide to carbon dioxide and/or converting nitric oxide to nitrogen. The compositions, articles and methods of the invention can be used to reduce the amount of carbon monoxide and/or nitric oxide present in mainstream smoke reaching the smoker and/or given off in secondhand smoke. The manganese oxide can be co-precipitated with the additive(s), or mechanically mixed with the additive(s) to form the manganese oxide mixture. The manganese oxide may have a lower light-off temperature than the additive, such that during smoking of the cigarette, the heat generated from the oxidation of carbon monoxide by manganese oxide is capable of activating the additive. The additive may include iron oxide (Fe2O3) nanoparticles.
