Special Issue Information
Dear Colleagues,
Nanoporous and nanostructrured metals have sparked increasing interest thanks to the versatility of morphology and the intriguing properties that can be employed in a wide range of applications. Characterized by a high specific surface area and possibility of tuning the shape and size of the nanostructured metals as a function of the synthesis parameters, they have been applied with success as catalysts, electrocatalysts, SERS substrates, sensors, and materials for energy and sieves.
This Special Issue is devoted to recent advances in the synthesis of nanoporous and nanostructured metals prepared by different techniques, including but not limited to dealloying and electrodeposition means. Experimental works focused on applications of nanoporous and nanostructured metals are welcome in this Special Issue.
In general, the topics of interest include the following aspects:
- Advanced synthesis and characterization of nanoporous metals, nanowires, nanoparticles, nanotubes, and all possible unconventional metal nano-shapes;
- Exploration of fields of catalysis, electrocatalysis, SERS, sensing, actuation, energy, sieves, and magnetic and other potential applications;
- Related effects of synthesis conditions on the final structure and properties of nanoporous and nanostructured metals.

Abstract: In this study, we report Nanoporous Gold (NPG) as an economic, efficient and stable alternative electrocatalyst for methanol electro-oxidation. The said sample has been successfully prepared from an Fe-rich metastable Au33Fe67 supersaturated solid solution acting as the precursor, which was formed into ribbons by the phenomenon of rapid solidification using melt-spinning technique. The as–quenched ribbon was then chemically dealloying in 1 M HCl at 70 °C for different durations of time. Homogeneous, free-standing and mechanically stable NPG sample was obtained with tunable ligament shape and size. The sample has been examined as an electrocatalyst for methanol electro-oxidation profiting off its large surface area. In a basic solution of methanol and KOH the sample displays a low peak potential of 0.47 V vs Ag/AgCl for methanol electro-oxidation with high peak current density of 0.43 mA/cm2. In addition, it demonstrates outstanding stability and high poisoning tolerance. Noteworthily, the fabrication process of the NPG sample from start to end has been intentionally opted to be sustainable, cost-effective, rapid and feasible. Usage of critical raw materials has been avoided. As a whole, the properties and results put forth by the NPG sample make it an inexpensive, sustainable and excellent alternative as an electrocatalyst for methanol electro-oxidation.
