Alloys have spurred considerable interest recently, since they can be implemented in kesterite-based solar cells, employed as negative electrodes in lithium-ion batteries, as corrosion resistant layers and as candidates for lead-free solders. An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by a metallic bonding character. An alloy may be a solid solution of metal elements (a single phase) or a mixture of metallic phases (two or more solutions). Intermetallic compounds are alloys with a defined stoichiometry and crystal structure.
Alloy nanoparticles are used in a wide variety of applications. In some cases, a combination of metals may reduce the overall cost of the material while preserving important properties. In other cases, the combination of metals imparts synergistic properties to the constituent metal elements such as corrosion resistance or mechanical strength. Examples of alloys are steel, solder, brass, pewter, duralumin, bronze and amalgams.
Nanostructured materials have attracted considerable interest due to their unique properties and their potential for numerous industrial applications. Various fundamental physical properties such as the melting point have been theoretically predicted and empirically proven to change as the material size decrease. Due to the importance of this nano-size effect in electronic materials, nanoalloys have been synthesized and studied recently as possible solder materials. However, their potent reactivity with respect to water and oxygen, along with a high surface-area to volume ratio favors an easy oxidation.
Two-component alloy nanoparticles based on Fe, Co, and Ni are of great interest in the catalysis of, for example, the Fischer–Tropsch synthesis or the decomposition of cellulose More than the single metals, bimetallic mixtures make it possible to tune carbon deposition and carbide formation rates, which are crucial for catalytic activity and lifetime or the adsorbate bond dissociation energies as a function of the metal dband center as described by the Newns–Anderson model. With bimetallic nanoparticles, catalytic performance is often also enhanced by their superior sintering resistance.
Silver-copper alloy nanoparticles are synthesized using a low temperature plasma bombardment method, well below the melting point of the sample constituents. The method can be used for any other materials to produce nanoparticles of them on any arbitrary substrates (even flexible substrates). It is easy to make a patterned structure of nanoparticles by this method. This method can produce clusters of nanoparticles and may be the produced films can be used in device fabrications such as transistors, single electron transistors, nanoparticles-based gas sensors etc. Optical measurements of as-prepared nanoparticles confirm the quantum behavior of the samples arising from decreasing the size and confinement.
