“…In addition to using the chemical processes in the PLIs, the physical sputtering process can also be used to synthesize alloy NPs, such as AuAg [121,244,245] and AuPd [246] by using the experimental setup as shown in Fig. 5.…”

Over the past decades, a new branch of plasma research, the nanomaterial (NM) synthesis by plasma-liquid interactions (PLIs), is rapidly rising, mainly due to the recently developed various plasma sources operated from low to atmospheric pressures. The PLIs provide novel plasma-liquid interfaces where many physical and chemical processes take place. By exploiting these physical and chemical processes, various NMs ranging from noble metal nanoparticles to graphene nanosheets can be easily synthesized. The currently rapid development and increasingly wide utilization of the PLI method naturally lead to an urgent requirement for presenting a general review. This paper reviews the current status of research on plasma-liquid 2 interactions for nanomaterial syntheses. Focus is on the comprehensive understanding of the synthesis process and perceptive opinions on the present issues and future challenges in this subject.

“…Their injection onto the IL surface and/or bulk phase could produce an atom/cluster concentration high enough to coalesce with each other and result in the formation of nanoparticles. 11,[22][23][24][25] Although it is difficult to know where the NPs' nucleation and particle growth occurs, it can be anticipate that (i) the nucleation starts in on the IL surface and then diffuses into the liquid phase where particle growth takes place; (ii) both processes occurs in on the IL surface; or (iii) the metal atoms and clusters could penetrate just below the liquid phase and both processes occur in the bulk IL phase (Figure 1). Regardless of the operative processes, the nanoparticle formation will be strongly dependent on the IL surface composition and the structural organization of the bulk phase.…”

Ionic Liquid Surface Composition Controls the Size of Gold Nanoparticles Prepared by Sputtering Deposition

The sputtering of gold foil onto 1-n-butyl-3-methylimidazolium tetrafluoroborate, hexafluorophosphate, bis(trifluoromethylsulfonyl)amide, or tris(fluoro)tris(perfluoroethane)phosphate ionic liquids (ILs) generates stable and well-dispersed gold nanoparticles (NPs) of 3-5 nm under conditions of 40 mA, 335 V, and 2 Pa Ar work pressure. The size and size distribution of these Au nanoparticles depends on various experimental parameters, particularly the surface composition of the IL and less so the surface tension and viscosity. Under the experimental conditions used here, both nucleation and NP growth seem to occur on the IL surface and the NP size changes with the changes in the IL surface composition, especially with the increase of the fluorinated content. Moreover, the NP size is independent of sputtering time but does depend on the discharge current. When higher discharge currents are used, more gold atoms hit the ionic liquid surface per unit time, changing the kinetics of particle growth on the surface of the IL.

“…The second strategy has been used to synthesize AuAg alloy NPs using a chemical reaction induced by sputter deposition of Ag onto IL solutions containing HAuCl 4 [28]. A red-shift in the surface plasmon resonance peak in the absorption spectra was detected when the concentration of HAuCl 4 was increased, indicating that AuAg alloy NPs were synthesized, similarly to the previously mentioned AuAg NPs.…”

“…First, metal NP synthesis using ionic liquids will be discussed, which includes the synthesis of single material NPs and the effect of sputtering conditions [19][20][21][22][23][24][25][26][27], various alloying strategies [15,23,24,28], and techniques for transferring synthesized NPs [29][30][31]. Subsequently, we discuss NP synthesis using low-volatile polymers, including the use of thiol compounds and transfer techniques [32][33][34][35][36][37][38][39].…”

Nanoparticles (NPs), which have been investigated intensively as electrocatalysts, are usually synthesized by chemical methods that allow precise size and shape control. However, it is difficult to control the components and compositions of alloy NPs. On the other hand, the conventional physical method, sputtering with solid substrates, allows for facile composition control but size control is difficult. Recently, "liquid medium sputtering" has been suggested as an alternative method that is capable of combining the advantages of the chemical and conventional physical methods. In this review, we will discuss NP synthesis via the liquid medium sputtering technique using ionic liquid and low-volatile polymer media. In addition, potential applications of the technique, including the generation of oxygen reduction reaction electrocatalysts, will be discussed.
