“…A discussion on the NP stabilization by host liquids can be found in section 2.2. [136,140,152,[190][191][192][193]. In the case of co-sputtered Au x Ag 1−x NPs, the mean diameter of alloy NPs increases with an increasing fraction of Ag [194].…”

“…In this setup the overall composition of the obtained Au/Pd alloy NPs is modified by tuning the sputtering time at each step. For example, if the NPs are synthesized with a Au/Pd ratio of 1:1 (equal time of sputtering of Pd and Au), the NPs composition, probed by STEM-EDS, ranges from 34 to 69 atom % Au for the same solution [ 136 , 191 – 192 ].…”

Sputter deposition of atoms onto liquid substrates aims at producing colloidal dispersions of small monodisperse ultrapure nanoparticles (NPs). Since sputtering onto liquids combines the advantages of the physical vapor deposition technique and classical colloidal synthesis, the review contains chapters explaining the basics of (magnetron) sputter deposition and the formation of NPs in solution. This review article covers more than 132 papers published on this topic from 1996 to September 2021 and aims at providing a critical analysis of most of the reported data; we will address the influence of the sputtering parameters (sputter power, current, voltage, sputter time, working gas pressure, and the type of sputtering plasma) and host liquid properties (composition, temperature, viscosity, and surface tension) on the NP formation as well as a detailed overview of the properties and applications of the produced NPs.

The young history of sputtering onto a liquid features great achievements in the green production of various metal and metal oxide nanoparticles (NPs) and nanoclusters (NCs). Studies on how the sputtering parameters affect the properties of NPs and NCs have elucidated their formation mechanism and marked a crucial role of liquid matrix in the nucleation and growth of particles, controlling their various properties. Current research has been devoted to making alloy bi-and trimetallic NPs with a high level of control over the NP structure, composition, and size via well-designed target systems, sputtering steps, and liquid matrix materials. In this minireview, we discuss the recent advances in the use of various types of targets to prepare different bi-and trimetallic NPs. In single target sputtering, systems with alternative configurations of metals, alloy targets, monometallic targets in sequence, and a combination of sputtering and chemical reactions have been developed. On the other hand, a double head system was introduced to widen the range of controllable sputtering parameters yielding more versatility in particle composition and fine structure. The synergistic and tuneable properties exhibited by the multi-metallic components in small NPs and NCs for their use in catalysis and optical applications are discussed.
