摘要： Preparing a porous hybrid media includes contacting porous media (e.g., strong base ion-exchange media) with an aqueous solution including aluminum ions to yield a aluminum-ion-containing porous media, contacting the aluminum-ion containing porous media with a reducing agent to impregnate elemental aluminum in the porous media, and oxidizing the elemental aluminum to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. In some cases, a pH of an aqueous mixture including the aluminum-ion-containing porous media may be adjusted to form a floc including aluminum hydroxide, and the aluminum hydroxide-containing porous media may be contacted with a reducing agent to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. The porous hybrid media may advantageously be prepared at low temperature (e.g., room temperature).

摘要： Porous nanocomposite fibers are fabricated by electrospinning a solution including a polymer, a solvent, and a nanomaterial. The resulting fibers can be used in the form of a filter to remove a variety of organic and inorganic contaminants from an aqueous environment, and provide a macroscopic matrix to facilitate separation of the nanomaterial from the aqueous environment.
