Nanoporous metallic alloys exhibit a wealth of intriguing properties compared to bulk fully-dense materials. Their ultra-high surface area−to−volume ratio, together with their low density and the possibility of hosting second-phase materials inside the porous frameworks, make these alloys useful for widespread technological applications that range from catalysts, filters, fuel cells or batteries to sophisticated platforms for drug delivery or biological labeling. The mechanical properties of these alloys (high elastic recovery, low Young’s modulus, ultra-high yield strain) foster additional functionalities for these materials, such as orthopedic implants with optimum biomechanical compatibility or nanoporous impact damper coatings with enhanced shock-resistance. This Special Issue welcomes contributions dealing with innovative strategies for synthesizing macro- (pore size > 50 nm), meso- (2 nm < pore size < 50 nm) and microporous (pore size < 2 nm) metallic alloys, such as via electrodeposition (by colloidal crystal and block-copolymer templating or by using hydrogen bubbling as a dynamic source of porosity), de-alloying, and sol-gel or nanosmelting (amongst others). Special emphases will be given to studies focusing on the control of the pore architecture, pore size distribution, and composition of the synthesized materials. Furthermore, experimental and theoretical reports that shed light on the interesting features of nanoporous metallic systems and their applications, as well as on advanced and innovative techniques for fully characterizing these type of materials, also fall within the scope of this Special Issue.

Title: Fe80Ga20 nanowire preparation at various pore diameters
Authors: Diana Pohl, Heike Schlörb

Abstract: Fe80Ga20 alloy thin films are electrochemically accessible from a simple aqueous electrolyte. In order to reduce the dimensionality of the alloy films large arrays of nanowires were deposited within nanoporous templates. It has been shown that, for sub-micrometer pore diameters, the simple electrolyte is suitable to completely fill the pores and to produce metallic nanowires whereas at pore diameters below 100 nm the restricted transport properties in the narrow pore geometry inhibit the growth of continuous nanowires. The extended hydrogen evolution produces large amounts of hydroxides that cannot be completely redissolved and removed from the high aspect ratio nanopores therefore leading to discontinuous nanowires. By modifying the electrolyte the hydroxide formation and incorporation can be prevented resulting in continuous metallic alloy nanowires of several micrometer length even at pore diameters far below 100 nm.
