Special Issue Information

Dear Colleagues,

Nanoporous metals with extremely large specific surface area and tunable porosity have gained considerable attention due to their outstanding optical, electrical, catalytic, and mechanical properties. A practical field to take full advantage of the excellent properties of nanoporous metals is thin film technology, which was found to be a successful choice for practical applications including sensors, micro-batteries, microfluidic flow controllers, etc. Recently, new application possibilities of nanoporous metal films on radiation tolerant material coatings have been tentatively explored due to their abundant free surface.

The aim of this Special Issue is to further advance the understanding of nanoporous metal films and broaden their application fields. Both experimental and theoretical works are welcome for this Special Issue.

In general, the topics of interest include but are not limited to the following aspects:

  • Effects and mechanisms of synthesis conditions on the final structure and properties of nanoporous metal films;
  • Advanced techniques on the preparation and characterization of nanoporous metal films;
  • Exploration of application fields in catalysis, actuation, sensing/biosensing, fuel cell, super capacitor and other potential applications;
  • Novel nanoporous metal films with better performance with hierarchical structures or composite components.

Cu30Al70 and Ag30Al70 multilayer precursor films were prepared by magnetron sputtering, respectively. Then the nanoporous Cu/Ag multilayer composite films were successfully prepared by selecting the appropriate H2SO4 solution as the dealloying solution. It was found that the nanoporous structure was stable in the dealloying solution. The morphology and structure of nanoporous multilayer films are mainly related to the phase composition of precursors. The structure of nanoporous multilayers can be simply regarded as the superposition of single-layer structures. Our work shows that nanoporous multilayers can be well-prepared by magnetron sputtering combined with dealloying. Full article
