“…This is an attractive aspect from the economical viewpoint which makes the method very suitable for large scale industrial production [25,26]. Previously, various nanomaterials such as LiF [27], ZnS [28], Cu 2 O [29] and FePt [30] A c c e p t e d M a n u s c r i p t 6 the effect of operational parameters on the output variable [31,32]. It has been considerably utilized to model and optimize various AOPs due to its ability to examine the interactions amongst factors, and determine the optimum region of the factors level [1,33,34].…”

“…In previous studies, Cu 2 O has been synthesized through various chemical [24,25], electrochemical [26,27], and mechanochemical pathways [28,29]. Although these methods resulted in Cu 2 O with new structures and photocatalytic efficiencies, many of them pose potential environmental risks as they require hazardous reactants (e.g., sodium hydroxide) or metal precursors (e.g., copper nitrite, copper chloride, copper sulfate), and often generate a high volume of by-product [30].…”

Cuprous oxide (Cu2O) was synthesized for the first time via an open bipolar electrochemistry (BPE) approach and characterized in parallel with the commercially available material. As compared to the reference, Cu2O formed through a BPE reaction demonstrated a decrease in particle size; an increase in photocurrent; more efficient light scavenging; and structure-correlated changes in the flat band potential and charge carrier concentration. More importantly, as-synthesized oxides were all phase-pure, defect-free, and had an average crystallite size of 20 nm. Ultimately, this study demonstrates the impact of reaction conditions (e.g., applied potential, reaction time) on structure, morphology, surface chemistry, and photo-electrochemical activity of semiconducting oxides, and at the same time, the ability to maintain a green synthetic protocol and potentially create a scalable product. In the proposed BPE synthesis, we introduced a common food supplement (potassium gluconate) as a reducing and complexing agent, and as an electrolyte, allowing us to replace the more harmful reactants that are conventionally used in Cu2O production. In addition, in the BPE process very corrosive reactants, such as hydroxides and metal precursors (required for synthesis of oxides), are generated in situ in stoichiometric quantity, providing an alternative methodology to generate various nanostructured materials in high yields under mild conditions.

“…Recently, various nanomaterials, such as magnetite, zinc oxide, cuprous oxide and nitrogen doped carbon nanoparticles were synthesized using this procedure. 20,[24][25][26] However, according to literature, there has been limited reports for the synthesis of nano sized silver particles by this process. 27 Poly(ethylene glycol) (PEG) is a synthetic polyether polymer frequently used medical applications, owing to its wide range of molecular weight, excellent solubility in aqueous medium, low toxicity, chain flexibility and its biocompatibility properties and in addition, it is biodegradable via its excretion from the body to form non-toxic metabolites.…”

“…44 Similar peaks were observed in PEG stabilized nano silver particles and also a few other peaks were (111), (200) and (311), respectively, as presented in Figure 4. XRD patterns also represent the face-centered cubic (FCC) structure of nano silver particles 26,47 and the data was found to correspond with the database in the JCPDS File No. 04-0783 of WinXpow software.…”

Nano silver particles with an average mean crystallite size of between 10 and 12 nm were synthesized from different molecular weights of poly(ethylene glycol) as a stabilizing agents, through solid state oxidation of silver nitrate using a higher energy planetary ball mill. Ultraviolet-Visible spectra were used to confirm the synthesis of nano silver particles. The surface plasmon resonance bands were observed around 410 nm. Fourier transformed infrared spectrum, X-ray diffraction, and transmission electronic microscopy techniques were used to characterize the nano silver particles synthesized. Thermal stability was determined using thermogravimetic analysis and the elemental composition of the sample was determined by energy dispersive X-ray analysis. The nano silver particles synthesized, exhibited very good antibacterial activity against Gram-positive bacteria (Bacillus) and Gram-negative bacteria (Pseudomonas aeruginosa). Based on the obtained results, it was additionally explored that the size and the stabilization of the nano silver particles synthesized, strongly depend on the molecular weight of poly(ethylene glycol).
