“…The latter is a common feature of compounds having a layered structure. The layered structure is known to be typical of silver carboxylates and is defined by the layer‐by layer ordering of the silver ions and the carboxylate anions [28,30–32] . XRD patterns are in a good agreement with the ICDD data (PDF 04‐0023, 04‐0008).…”

“…Similar processes in the formation of metallic nanoparticles were found previously when studying the thermal and photochemical decomposition of silver carboxylates with different carboxylic acid chain length. [28] Silver nanoparticles of 1-2 nm in size were reported to be first formed in the salt matrix, and then they grow through coagulation. In this study, we have demonstrated that silver nanoparticles are formed on the carboxylate crystals (Figure 7).…”

“…Earlier, a simple, promising and easily scalable polyol method, based on the reduction of silver carboxylates with different carbon chain lengths in ethylene glycol at relatively low temperatures, 100–150 °C, has been proposed for the preparation of silver nanoparticles [27,28] . The features and mechanism of the polyol synthesis of silver nanoparticles using solid carboxylates have also been investigated [29] .…”

Silver nanoparticles are synthesized by reducing silver alkyl carboxylates at their high concentrations with ethylene and propylene glycol without a common use of polymeric dispersants and stabilizers. The effects of alkyl chain structure on the morphology and size of silver particles have been studied by scanning electron microscopy, transmission electron microscopy, powder X‐ray diffraction, differential scanning calorimetry, and thermogravimetric analyses. The carboxylates that have been investigated are silver caprylate, laurate, 2‐butyloctanoate, and 2‐ethylhexanoate. It was found that the reduction temperature of straight‐chain alkyl carboxylates is in the 110–120 °C range. The particles prepared under these conditions are perfectly spherical in shape and their average size varies from 20 to 40 nm. In the case of the branched structure, the reduction process starts at around 80 °C and produces irregularly shaped silver particles with a size of 150 to 450 nm. Possible ways of controlling the parameters of the synthesized nanoparticles are proposed. This study proposes a simple and easily scalable method to prepare silver nanoparticles stabilized by a non‐polymeric stabilizer. The as‐synthesized silver particles may have applications as metallic fillers in ink and paste formulations for 2D and 3D printing to fabricate functional components and devices.

“…The polyol process is another common wet chemical method used for the synthesis of silver nanostructures. The polyol process is typically performed at 120-160 °C by utilizing ethylene glycol as the solvent and reducing agent and PVP as the capping agent in the presence of a small amount of salt mediator [247][248][249]. Although the polyol process is a non-hazardous and widely accepted method for the synthesis of silver nanostructures, there are some disadvantages associated with it.…”

The significance of silver nanostructures has been growing considerably, thanks to their ubiquitous presence in numerous applications, including but not limited to renewable energy, electronics, biosensors, wastewater treatment, medicine, and clinical equipment. The properties of silver nanostructures, such as size, size distribution, and morphology, are strongly dependent on synthesis process conditions such as the process type, equipment type, reagent type, precursor concentration, temperature, process duration, and pH. Physical and chemical methods have been among the most common methods to synthesize silver nanostructures; however, they possess substantial disadvantages and short-comings, especially compared to green synthesis methods. On the contrary, the number of green synthesis techniques has been increasing during the last decade and they have emerged as alternative routes towards facile and effective synthesis of silver nanostructures with different morphologies. In this review, we have initially outlined the most common and popular chemical and physical methodologies and reviewed their advantages and disadvantages. Green synthesis methodologies are then discussed in detail and their advantages over chemical and physical methods have been noted. Recent studies are then reviewed in detail and the effects of essential reaction parameters, such as temperature, pH, precursor, and reagent concentration, on silver nanostructure size and morphology are discussed. Also, green synthesis techniques used for the synthesis of one-dimensional (1D) silver nanostructures have been reviewed, and the potential of alternative green reagents for their synthesis has been discussed. Furthermore, current challenges regarding the green synthesis of 1D silver nanostructures and future direction are outlined. To sum up, we aim to show the real potential of green nanotechnology towards the synthesis of silver nanostructures with various morphologies (especially 1D ones) and the possibility of altering current techniques towards more environmentally friendly, more energy-efficient, less hazardous, simpler, and cheaper procedures.

“…However, some reports indicate that the chemical reduction method provides well control under the structure and morphology of the AgNPs [11][12][13][14][15]. Specifically, reducing agents as sodium borohydride (NaBH 4 ) and ethylene glycol (EG) offer an excellent alternative to obtain silver nanoparticles sizes and morphologies controlled [16][17][18][19][20][21][22].…”

Nanoparticles of Ag with different sizes and structures were obtained and studied. Two methods for reductions of Ag ions were employed, chemical reduction by sodium borohydride and ethylene glycol. Cuboctahedral and icosahedral structures were obtained. Molecular simulations were carried out in order to evaluate the reactivity of both structures. On the other hand, the electrochemical activity and antibacterial effect (E. coli) of the cuboctahedral and icosahedral structures were measured experimentally. The results obtained by molecular simulation, cyclic voltammetry, and antibacterial effect were compared and discussed in this work.
