Synthesis and Modeling of Alloy Nanoparticles

Résumé

Nanoalloys, which are composed of two or more elements interacting through metallic bonds, are a wide class of nanostructures occupying a focal point of research across a diverse range of sectors. [1] This is due to their versatile applications and unique physicochemical properties, critically depending on the precise control over composition and structure. [2-4] In energy, they play a fundamental role in the development of fuel cells, batteries, and solar cells by enhancing energy conversion and storage efficiencies. Environmental science leverages nanoalloys for pollution control, such as CO2 reduction and catalytic water treatment. In medicine and healthcare, they are exploited for imaging, targeted drug delivery, and biosensing technologies.

Additionally, they have a consolidated role in materials science, particularly in the synthesis of novel coatings, sensors, and lightweight yet durable materials. Magnetism, quantum technologies and fine chemicals production are only some of the other sectors where nanoalloys received great attention and contributed to the most recent advancements.

The synthesis, modeling and investigation of alloy nanoparticles bring together transversal competences from physics, chemistry and materials science, both from the theoretical and experimental perspective.

ChemPhysChem is a natural forum for the dissemination of scientific results concerning nanoalloys, as showcased through this special collection which includes the most relevant contributions appeared in the last four years.

The catalytic properties of multielement nanoparticles are better investigated in their most ideal configuration, that is without any coating or capping layer. [5,6] For this reason, new synthetic techniques such as laser assisted synthesis in liquid [7-9] are being increasingly exploited for the production of surface-clean alloy nanocrystals, in addition to traditional routes such as sputtering, [10] impregnation followed by calcination, [11] chemical reduction, [12] or electrodeposition. [13] For instance, catalytic CO oxidation, [10]
