Abstract
High surface area skeletal metal catalysts and methods of producing such catalysts are described. The production involves solidification of certain eutectic compositions to produce a microstructure of intermetallic fibers in solid solution matrix. The matrix is preferentially removed to provide loose intermetallic fibers which may then be leached to provide a porous structure. Directional solidification is a preferred step in the production process.
