“…The processes of obtaining of MNPs and M 1 M 2 NPs should correspond to the following basic modern criteria: (1) the control of the geometry and the composition (for binary) of nanoparticles; (2) “green” synthesis; and (3) manufacturability. Regardless of the method of synthesis (chemical [ 9 , 10 ], electrochemical [ 11 , 12 ], or physicochemical [ 13 ]), the controlled synthesis is the main condition for its effectiveness. “Green” synthesis is based on the use of nontoxic precursors, primarily reducing agents and surfactants of natural origin, such as plant extracts [ 9 ] and microorganisms [ 10 ].…”

“…“Green” synthesis is based on the use of nontoxic precursors, primarily reducing agents and surfactants of natural origin, such as plant extracts [ 9 ] and microorganisms [ 10 ]. “Green” synthesis also includes the electrochemical methods due to the cathodic reduction of metal ions and the use of nontoxic surfactants [ 11 – 13 ].…”

“…Manufacturability of synthesis of MNPs and M 1 M 2 NPs means, first of all, the maintenance of a high rate of processes. This is provided by electrochemical microplasma [ 13 ] and ultrasound [ 14 – 21 ]. Herein, we will consider ultrasound as one of the effective factors of MNPs engineering intensification.…”

The main features of the “green” synthesis of metallic nanoparticles (MNPs) by the sonoelectrochemical methods are manufacturability, environmental friendliness, and the possibility of controlling the geometry of the forming particles. The electrochemical reduction technique allows efficiently designing the metal nanoparticles and provides the control of the content of components of bimetallic nanoparticles, as well as minimizing the number of precursors in working solutions. Due to the generation of turbulence, microjets, and shock waves, ultrasound increases mass transfer and formation of radicals in aqueous solutions and, accordingly, accelerates the processes of nucleation and growth of MNPs. Therefore, this hybrid method, which combines electrolysis and ultrasound, has attracted the interest of researchers in the last two decades as one of the most promising techniques. The present work presents a short analysis of the reference literature on sonoelectrochemical synthesis of metallic and bimetallic nanoparticles. The main factors influencing the geometry of nanoparticles and their size distribution are analyzed. The use of pulsed ultrasound and pulsed current supply during sonoelectrochemical synthesis is especially effective in designing MNPs. Emphasis is placed on the role of surfactants in the formation of MNPs and sacrificial anodes in providing the algorithm: “anodic dissolution-electrochemical reduction of metal-nucleation and formation of МNPs.” It is noted that ultrasound allows synthesizing the MNPs and M1M2NPs during the galvanic replacement, and an analogy of the formation of nanoparticles by sonogalvanic replacement and sonoelectrochemical method is shown.

The great demand for functional, particularly biologically active, metal nanoparticles has led to the search for technologically effective, green, and controlled methods of synthesizing these metal nanoparticles. Plasma glow discharge is one of the most promising techniques in this direction. The results of studies based on the synthesis of colloidal solutions of stabilized silver nanoparticles (AgNPs) by the microplasma method in solutions of a nontoxic surfactant sodium polyacrylate (NaPA) are presented. It is shown that AgNPs with a size of 2–20 nm are formed in solutions of 0.05–0.2 mmol⋅L−1 AgNO3 + 5 g⋅L−1 NaPA at U = 250 V by tungsten cathode plasma glow discharge. At 20°C, the yellow solutions are formed with λmax ≈ 410 nm, which are stable during long-term storage. It was found that the process of AgNPs formation corresponds to a first-order reaction on the AgNO3 concentration. Its value has little effect on the geometry of nanoparticles, so the Ag(I) concentration in solution is one of the main factors influencing the rate of microplasma synthesis of AgNPs. The antimicrobial activity of synthesized AgNPs solutions against strains of Escherichia coli, Staphylococcus aureus, and Candida albicans was established.
