Abstract:
1. A method for in-situ coating a matrix with magnetic nanoparticles comprising: combining a metal precursor, containing a metal salt, with a liquid polyol to form a solution; introducing a matrix into the solution; stirring the solution; and heating the solution to a predetermined temperature, wherein the magnetic nanoparticles are formed through reduction of the metal salt, wherein the magnetic nanoparticles precipitate out of solution to form a coating on a surface of the matrix and wherein the matrix is selected from a group consisting of: a porous ceramic body, ceramic foam, polymer foam of varying porosity, a porous metal body, carbon foam, a ceramic felt, an alumina membrane, an alumina filter, a metal foam and carbon fibers.
