“…There are many partial interpretations [42,44,46,48,55,57,[69][70][71][72][73] on the NM syntheses from the PLIs, here we summarize them and try to give a general mechanism. It is worth pointing out that the plasmas are operated at tenths kPa to atmospheric pressure and they usually have a small size and low gas temperature due to the volatility of water.…”

“…A successful route to synthesize NMs, solution-based synthesis, is based on etching and/or reduction of metal ions in solutions [40,41], which has proved a powerful tool for forming NMs with various sizes, shapes as well as compositions. Since the plasma can provide electrons and radicals, and the metal ions can dissolve in the liquids, this unique plasma-liquid system is strongly attracted to the NM syntheses, and they fertilize and active a rapidly rising field of the PLI-based NM syntheses [42][43][44][45][46][47][48][49] in recent decades due to the strong requirement of large-scale syntheses of NMs and the fast development of various plasma sources.…”

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.

“…Plasma generation in a solution, rather than in a gas, has recently been proposed for the synthesis of nanoparticles; methods include the plasma jets [11], plasma-chemical reduction [12], microplasma reduction [13], influence of glow discharge [14], arc in water [15][16][17][18], arc discharge processes [19], solution plasma processing (SPP) [20][21][22][23], cathodic discharge [24,25], and laser-induced plasma [26]. Some of these methods successfully produced small (<10 nm) uniform nanoparticles.…”

Abstract. Because of the easy massproduction, synthesis of metallic nanoparticles from a solution plasma is an attractive method. However, a solution plasma produces a highly inhomogeneous electric field via transition to full-plasma, and the products are partially oxidized and agglomerated, with a wide size-distribution. Here, we show a simple method of suppressing oxidation of products. An electrode tip was shield by a glass tube and a voltage of up to 180 V was applied with the electrolyte of 0.1 M NaOH solution. Significantly, the edge-shield was quite effective for maintaining partially glow discharge. The results were (1) surface temperature of the electrode less than 100 °C, (2) main phase of metallic nickel evaluated by XRD, and (3) nanoparticles of an average size of 220 nm. These results showed the potential for an application to the production of nanoparticles.
