Electrolytic Synthesis and Characterization of Silver Nanopowder

Abstract

This work reports a simple, novel, cost effective and eco-friendly electrolytic synthesis of silver nanoparticles using AgNO 3 as metal precursor. The synthesis rate is much faster than other methods and this approach is suitable for large scale production. They are characterized by XRD, SEM and FT-IR techniques to analyze size, morphology and functional groups. XRD studies reveal a high degree of crystallinity and monophasic Ag nanoparticles.Their particle size is found to be 24 nm and specific surface area (SSA) is 24 m 2 g -1 . Analysis of Ag nanoparticles SSA reports that increasing their SSA improves their antibacterial actions. Microbiology assay founds that Ag nanoparticles are effective against E.coli and B.megaterium bacteria.SSA of bacteria analysis reveals that it plays a major role while reacting with antimicrobial agents.

Biosynthesis of silver nanoparticles from Premna serratifolia L. leaf and its anticancer activity in CCl4-induced hepato-cancerous Swiss albino mice

“…1 Optical density of silver nanoparticles synthesized using P. serratifolia leaf extract 64.69°and 77.62°, corresponding to 111, 200, 220, and 311 planes of the face-centered cubic (fcc) for silver, respectively. This is in agreement with the results obtained by other workers (Martinez-Castanon et al 2008;Parikh et al 2011;Theivasanthi and Alagar 2011). Moreover, few small insignificant impurity peaks were also observed, which may be attributed to other organic substances in reaction mixture.…”

Konjac Biomolecules Assisted–Rod/Spherical Shaped Lead Nano Powder Synthesized by Electrolytic Process and Its Characterization Studies

“…The average dislocation density of lead nanoparticles found to be as 11.1 × 10 14 m -2 . The dislocation density of electrolyzed silver nanoparticles 9.2 × 10 14 m -2 has been noted from our earlier report [28]. It is observed that the sample lead nanoparticles harder than electrolyzed silver nanoparticles.…”

“…The equations for the calculation of lattice constant, particle size, instrumental broadening, dislocation density, theoretical density, crystallinity index, morphology index and specific surface area are in our earlier report [28], presented in other reports as per the references as well as in the supplementary file.…”

“…For studying, changes in Specific Surface Area (SSA) of nanoparticles and its effects on antibacterial activities nanoparticles, we have compared SSA of lead nanoparticles and silver Nanoparticles of our earlier study [28]. The details are presented in Table 3.…”

Improving cytotoxicity against cancer cells by chemo-photodynamic combined modalities using silver-graphene quantum dots nanocomposites

“…It is observed that GQDs (point out by yellow font) are attached on the surface of Ag nanoparticles, where the d-spacing planes of Ag and GQDs (marked in white font) can be distinguished. The d-spacing of 0.145 nm corresponds to the (220) plane of silver, 44 and the d-spacing of 0.214 nm corresponds to the (110) plane of GQDs. 41,45 We used the XRD technique to identify the presence of silver and GQDs in the nanocomposites.…”
