“…AuNPs have been synthesized from reducing AuCl4 -by plasma in aqueous solutions [48,49,[163][164][165][166]. Without considering the other mechanisms, Hieda et al [48], Sato et al [49] and Bratescu et al [164] just considered that H radicals produced by plasma acts as the reducing species. Interestingly, Sato et al [49] investigated the dynamic of the AuNPs formation during the plasma ignition with time-resolved TEM.…”

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.

“…Mainly, four approaches remained under operation: (1) DC plasma discharge in contact to liquid [26][27][28][29], (2) DC glow discharge plasma in contact to liquid [30], (3) pulse plasma discharge inside the liquid [31][32][33][34][35][36], and (4) gas-liquid interface discharge [37]. Hydrogen peroxide was the most probable reaction mechanism to synthesize gold nanoparticles [26][27][28][29].…”

“…Hydrogen radicals generated in the discharge where their rate increased consistently with the external field and, due to dissolution of nanoparticles, reduction rate lowered which was the cause of anisotropic growth [34]. The influence of Brownian motion along with the surface charge of nanoparticles explained their stability [35] and negatively charged surface of nanoparticles kept them away from agglomeration [36].…”

-Developing particles of different anisotropic shapes are the hot topic since decades as they guarantee some special features of properties not possible through other means. Again, controlling atoms to develop certain size and shape particle is a quite challenging job. In this study, gold particles of different shapes are developed via pulse-based electronphoton-solution interface process. Gold atoms of certain transition state develop monolayer assembly at solution surface around the light glow (known in argon plasma) being generated at bottom of copper capillary (known in cathode). The rate of uplifting gold atoms to solution surface is being controlled by forcing energy (travelling photons) pursuing electrons and high energy photons (in high density) entering to solution. Gold atoms dissociated from the precursor under dissipating heat energy into the solution supplied under propagating photons characteristic current through immersed graphite rod (known in anode). Placing packets of nano shape energy of tuned pulse protocol over compact monolayer assembly comprising transition state atoms develop tiny-sized particles of formed shape. On separation of joint tiny particles into two equilateral triangular-shaped tiny particles, exerting forces of surface format elongate atoms of one-dimensional arrays converting them into structures of smooth elements. Due to immersing level of force, such tiny-shaped particles pack from Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted:

“…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.
