Title: Pyrophoric metal-carbon foam composites and methods of making the same

Abstract

A method for creating a pyrophoric material according to one embodiment includes thermally activating a carbon foam for creating micropores therein; contacting the activated carbon foam with a liquid solution comprising a metal salt for depositing metal ions in the carbon foam; and reducing the metal ions in the foam to metal particles. A pyrophoric material in yet another embodiment includes a pyrophoric metal-carbon foam composite comprising a carbon foam having micropores and mesopores and a surface area of greater than or equal to about 2000 m.sup.2/g, and metal particles in the pores of the carbon foam. Additional methods and materials are also disclosed.
