Electrochemical Method for Ag-PEG Nanoparticles Synthesis

Abstract

In this work we present an electrochemical method to successfully prepare silver nanoparticles using only polyethylene glycol as stabilizer and without any other reactive. Here we study the use of the polymeric stabilizer to allow the introduction of a potential tool to reinforce the control of the size and shape of the nanoparticles throughout the synthesis process. The evolution of the reactions was followed by UV-Vis spectroscopy. The electrode processes were characterized by cyclic voltammetric measurements and the final product was studied by Atomic Force Microscopy, Transmission Electron Microscopy, and X-Ray Diffraction. The influences of the current density, polymer length, and concentration media were analyzed.

Electrochemical synthesis, characterisation and phytogenic properties of silver nanoparticles

“…Owing to the wide range of applications offered by nanoparticles in various fields, different approaches have been deliberated for their synthesis. Several methodologies were developed to obtain Ag NPs of wide ranging surface morphology including, biosynthesis (Vankar and Shukla 2012;Christensen et al 2011, Shanmugavadivu et al 2014, microwave processing (Pal et al 2013), laser ablation (Amendola et al 2012), gamma irradiation (Gasaymeh et al 2010), electron irradiation (Misra et al 2013), electrodeposition (Khaydarov et al 2008;Sanchez et al 2000;Roldan et al 2013), green synthesis (Shameli et al 2012;Pandey et al 2012;Ahmad and Sharma 2012), sonoelectrochemical synthesis (Socol et al 2002); chemical reduction (Sileikaite et al 2009), photochemical method (Kutsenko and Granchak 2009), thermal decomposition, radiolytic reduction (Saion et al 2013) etc., Among these techniques, bottom-up methods are frequently adopted for the synthesis of Ag NPs, since they offer easy and expedient route for the synthesis of Ag NPs.…”

Rapid green synthesis of silver nanoparticles by aqueous extract of seeds of Nyctanthes arbor-tristis

“…Among all nanoparticles, silver nanoparticles have potential applications in the fields of agriculture (Park et al 2006), forensic science (C. Antonio 2008), chemistry (Li et al 2009), waste management, pollution control, solar cells, and biomedicine. Various chemicals and physical methodology are listed for the synthesis of nanoparticles such as chemical reduction (Kholoud et al 2010), photochemical reduction (Kshirsagar et al 2014;Scaiano et al 2009), and electrochemical reduction (Roldán et al 2013;Yanga et al 2011). These processes sometimes depend on the toxic chemicals (such as solvent, reducing agent, capping agent) which may not be harmful for the synthesis of nanoparticles in industrial purposes but it is always expected to synthesize the nanoparticles in greener approach in the application of environmental and biological issues.…”

Synthesis and anti-fungal effect of silver nanoparticles–chitosan composite particles

“…1 Silver nanoparticles have been applied in many fields including photonics, micro-electronics, photocatalysis, lithography, and surface-enhanced Raman spectroscopy. 2,3 Several types of chemical and physical technologies, such as chemical reduction, [4][5][6] electrochemical reduction, [7][8][9] photochemical reduction, [10][11][12] and heat evaporation 13,14 have been developed for the synthesis of silver nanoparticles. In recent years, bio-or green-synthesis of silver nanoparticles has become an emerging science.…”
