Abstract
The present invention is directed to nanoporous metal membranes and methods of making nanoporous metal membranes from metal leaf. At least a portion of the metal leaf is freely supported by a de-alloying medium for a time effective to de-alloy the metal leaf. After the porous membrane is formed, the membrane may be re-adhered to a substrate and removed from the de-alloying medium. The de-alloying process may be thermally and electrically influenced.
