Abstract
Silver-amended carbon materials containing silver nanoparticles are prepared by a process involving an initial reduction of a porous carbon material, followed by contacting the reduced porous carbon material with an aqueous solution of a silver salt. Such silver-amended carbon materials may contain a relatively high loading of silver nanoparticles on both the outside surface and within the interior of the porous carbon material and are useful for disinfecting and/or otherwise purifying fluids such as microbe-containing fluids.
