Abstract
Multiple approaches to fabricate nanoporous nickel (np-Ni) thin films from NiCu, NiAl, NiFe and NiMg precursors are presented. Deposition of precursor films, dealloying and characterization of the nanoporous films by electron microscopy are discussed. All precursor alloys can yield np-Ni. However, dealloying of NiMg precursor films yields the most consistent, open-porosity structure with a ligament size of 7 nm, comparable to that of Raney nickel.
