Magnesium Alloy Precursor Thin Films for Efficient, Practical Fabrication of Nanoporous Metals
Abstract
An improved approach to fabrication of nanoporous (np) metals is demonstrated for several metallic systems that were successfully created by dealloying magnesium-based precursor alloys (also containing iridium, nickel, gold, or osmium-ruthenium). A significant advantage is that magnesium alloys can be dealloyed effectively using water or, if needed, dilute acetic acid. The crystal structures of magnesium-based precursor films were significantly different from those of alloys commonly used as precursors. This approach should be generally applicable to np metal synthesis.
