摘要：
This invention relates to modified high surface area materials, such as nanoparticlesthat are coated with metal ions, and articles treated with the modified high surfacearea materials. The modified nanoparticles have active sites that bind variousgases and/or odorous compounds, thereby removing these compounds from a mediumsuch as air or water. Metal ions are adsorbed onto the surface of the nanoparticleand bound strongly to the surface. By selection of the metal ion, specific gaseouscompounds and/or odorous compounds can be targeted and removed efficientlyand effectively from both aqueous phase and from the air. The modified nanoparticlesare applied to nonwoven webs to provide odor removing articles for industrialand consumer use in refrigerators and trash containers.
