Indeed, recently in the literature, it has been shown that NP Al is a promising material for hydrogen generation [16] and ultraviolet (UV) plasmonic applications, such as Surface Enhanced Raman Spectroscopy (SERS) and Metal Enhanced Fluorescence (MEF) [17]. Plasmon resonance of Al nanostructures can be tuned by varying their size, structure, and oxide content from UV to near-infrared (NIR) [18; 19]. These features make this material a promising valuable low-cost, self-supported, and tunable substrate for UV and visible-light SERS and MEF. Moreover, NP Al could also be of interest as a catalyst by matching the unique surface area and catalytic properties of NP metals with the Al catalytic activity for various organic reactions [20]. Furthermore, the use of self-standing nanostructured material such as a NP metal for catalytic purposes could allow taking the advantages of both homogeneous and heterogeneous catalysis without the pelletizing process, which can be required when nanoparticles are employed as catalysts [21; 22]. NP Al fabrication is challenging because of the high Al reactivity toward oxygen and water. The first of the few papers illustrating the preparation of a NP Al has been reported by [PERSON] et al. ; it describes a fabrication method based on the electrochemical dealloying of Zn or Mg [23]. Later, [PERSON] et al. [16] demonstrated that NP Al could be prepared by this method in non-aqueous electrolytes under an Ar atmosphere, thus preventing both Al oxidation during its removal and the ligament coarsening observed by [PERSON] et al. [24] during Galvanic Replacement Reaction. In this work, we address the production of NP aluminum by VPD by treating an Al\({}_{20}\)Zn\({}_{80}\) nanocomposite at a relatively high temperature under a vacuum. Three steps are involved in the fabrication method: mechanical alloying of Al and Zn powders under an Ar atmosphere, cold-pressing of powders into pellets, and Zn removal during a thermal treatment under vacuum conditions. Although ligament coarsening could occur because of the relatively high temperature required with VPD, this preparation method is promising because of its ease and the possibility of fabricating relatively large amounts of materials. Structure features have been investigated at different magnifications by Scanning Electron Microscopy (SEM) and Serial Block Face-Scanning Electron Microscopy (SBF-SEM), while surface area and pore volume have been characterized by N\({}_{2}\) physisorption measurements. Since mechanical properties of NP Al are not studied in an exhaustive way, nanoindentation tests have been performed to estimate Young's modulus for the first time. A further investigation of microstructure morphology has been performed by using a phenomenological model based on fractal geometry. Moreover, relevant applications of fractal modeling show its reliability not only to reproduce structure features of several materials, but also to predict their behavior under different conditions [25; 26; 27]. In this case, it has been possible to calculate the specific surface (by simple geometrical measurements) and [PERSON]'s modulus (by resolving series and parallel springs' patterns after model conversion), which have then been successfully compared with experimental measurements.
