“…Porous metals have important technological potential since they offer a unique combination of high conductivity, high surface area, and light weight properties into one material system. They have a wide range of potential applications including thermal management, energy absorption, catalysis, sensing, or filtration at high temperatures, energy generation, and/or storage, lightweight optics, vibration/sound absorption, etc. Despite the significant need for these materials, at present, there are only limited methods to obtain them, such as direct assembly from metal nanoparticles, combustion synthesis, electroplating (or electroless‐plating) on fabricated microtemplates, which are complicated and costly in manufacturing, and some of the processes are toxic and involve safety concerns.…”

Highly porous metal nanowire aerosponges are produced by direct assembly of the Cu nanowire in situ during their synthesis. Such a method offers not only great simplicity, but also excellent properties such as extremely low densities, high electrical conductivities, and remarkable mechanical properties. Furthermore, these Cu aerosponges exhibit excellent wicking behavior, suggesting their potential for heat-exchange applications in heat pipes.

“…Noble metal bimetallic NPs, such as AgAu and AgCu exhibit enhanced surface plasmon resonance (SPR) with visible light at well-defined frequencies and when hosted in a dielectric matrix, they can give rise to enhanced optical effects in SERS which makes them ideal substrates in detection of chemical and biological species (Ferrando et al, 2008;Bigall et al, 2009;Chen et al, 2011b;Cortie and McDonagh, 2011;Fan et al, 2013;López Lozano et al, 2013;Tang et al, 2014;Wen and Eychmüller, 2017). The incident light interacts with the structural units of the aerogels in sub-optical wavelengths and generates intense local electromagnetic field at the so-called "hotspots" between NPs leading to signal enhancement.…”

Aerogels are a unique class of materials due to their low density, high porosity, high surface area, and an open and interconnected pore structure. Aerogels can be organic, inorganic and hybrid with a plethora of surface chemistries. Aerogel-based products for thermal insulation are already in the market and many studies are being conducted in many laboratories around the world to develop aerogel-based products for other applications including catalysis, adsorption, separations, and drug delivery. On the other hand, bimetallic nanoparticles dispersed on high surface area carriers, which have superior properties compared to their monometallic counterparts, are used or are in development for a wide variety of applications in catalysis, optics, sensing, detection, and medicine. Investigations on using aerogels as high surface area carriers for dispersing bimetallic nanoparticles are leading to development of new composite materials with outstanding properties due to the remarkable properties of aerogels. The review focuses on the techniques to synthesize these materials, their properties, the techniques to tune their pore properties and surface chemistry and the applications of these materials.

Der Begriff Aerogel beschreibt im Wesentlichen eine besondere geometrische Struktur der Materie, die materialunabhängig ist und keinem speziellen Syntheseverfahren unterliegt. Grundsätzlich können daher Aerogele aus unzähligen Materialien bestehen, wodurch die Anwendungsmöglichkeiten nahezu unbegrenzt sind. Dasselbe trifft auf Nanopartikel zu. Diese werden ebenso durch ihre geometrischen Eigenschaften definiert. In den letzten Jahrzehnten standen daher nanoskalige Materialien im Fokus der Forschung, und es entwickelten sich mögliche Anwendungen in vielen naturwissenschaftlichen Bereichen. Heute ist eine Vielzahl an Metall‐, Halbleiter‐, Oxid‐ und anderen Nanopartikeln durch kolloidale Synthesen zugänglich. Dennoch ist es für eine Anwendung oft notwendig, dass diese Materialien zuvor in makroskopische Strukturen angeordnet werden. Dieser Aufsatz gibt eine ausführliche Übersicht über die Entwicklung, die die Welt der kolloidalen Nanopartikel und der Aerogele miteinander vereint. Ermöglicht wurde dies durch die kontrollierte Destabilisierung der vorab gebildeten Nanopartikel, die zu einer Anordnung der Nanopartikel zu einem dreidimensionalen, makroskopischen Netzwerk führt. Dieses revolutionäre Konzept verleiht die Möglichkeit, präzise kontrollierte Nanopartikel als Grundbausteine für makroskopische, poröse Strukturen mit einstellbaren Eigenschaften zu nutzen.
