ABSTRACT:
This invention relates to modified high surface area materials, such as nanoparticles that are coated with metal ions, and articles treated with the modified high surface area materials. The modified nanoparticles have active sites that bind various gases and/or odorous compounds, thereby removing these compounds from a medium such as air or water. Metal ions are adsorbed onto the surface of the nanoparticle and bound strongly to the surface. By selection of the metal ion, specific gaseous compounds and/or odorous compounds can be targeted and removed efficiently and effectively from both aqueous phase and from the air. The modified nanoparticles are applied to nonwoven webs to provide odor removing articles for industrial and consumer use in refrigerators and trash containers.
