UV-Light Mediated Biosynthesis of Silver Nanowires; Characterization, Dye Degradation Potential and Kinetic Studies

Abstract

Herrin, a simple and eco-friendly method for the synthesis of silver nanowires (Ag-NWs) has been reported. Silver nanowires were synthesized using Psidium guajava seed extract that acted as a reducing agent as well as a stabilizing agent for silver nitrate solution. Synthesis was carried out at 50 °C temperature under continuous UV-irradiation. Silver nanowires were initially characterized by a UV-visible and FTIR spectrophotometer. In addition, morphology and particle size of synthesized Ag-NWs were determined using Field Emission Scanning Electron Microscopy and X-ray diffraction (XRD) techniques. Nanowires were found to have 12.8 μm length and 200–500 nm diameter and cubic phase morphology. Furthermore, the catalytic potential of Ag-NWs for the degradation of methyl orange dye (MO) was determined. The selected dye was degraded successfully that confirmed the catalytic potential of Ag-NWs. The authors concluded that Ag-NWs can be synthesized using plant extract having excellent morphological features as well as impressive catalytic potential.

Silver Nanowire-PVB Composite for Reflective Heat Coating

“…A peak was evident for all samples at around 300 nm. The characteristic peak of Ag nanowires is observed from 300-440 nm because of the electron oscillation at the conduction band [20]. Hence, this confirms the presence of Ag nanowires in the samples.…”

“…Appearance of slight turbidity and color change indicated the synthesis of NPs. Both the solutions were separately centrifuged and dried at 70 • C for 3 h. The dried material thus obtained is stored for characterization [28,29].…”
