Analysis of Crystallographic Structures and Properties of Silver Nanoparticles Synthesized Using PKL Extract and Nanoscale Characterization Techniques

Abstract

In this cutting-edge research era, silver nanoparticles impose a substantial impact because of their wide applicability in the field of engineering, science, and industry. Regarding the vast applications of silver nanoparticles, in this study, the crystallographic characteristics and nanostructures of silver nanoparticles extracted from natural resources have been studied. First, biosynthetic silver nanoparticles were synthesized using the Pathor Kuchi leaf (PKL) extract as a mediator, and their crystal structures and characteristics were analyzed by UV–visible absorption spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and energy-dispersive X-ray (EDX) analysis. The average crystallite size of the synthesized silver nanoparticle was determined to be 20.26 nm, and also the lattice strain, intrinsic stress, and dislocation density were measured to be 2.19 × 10–3, 0.08235 GPa, and 3.062045 × 10–3/nm2, respectively. Further, the prepared sample of silver nanoparticles shows four peaks in the X-ray diffraction pattern, which correspond to the (111), (200), (220), and (311) face-centered cubic (FCC) crystalline planes. The outstanding finding of this work was that when the lattice parameters of the precursor were increased, the volume of the material did not considerably change, but the particle size decreased. Second, it was clearly demonstrated that this straightforward method is a clean, cost-effective, environmentally sustainable, nontoxic, and efficient route for the synthesis of silver nanoparticles (Ag NPs) using PKL leaf at ambient temperature, which also satisfies the green chemistry requirements. Finally, this study demonstrates the scope for the production of silver nanoparticles using low-cost natural resources.

Structural and optical properties of polymer blend nanocomposites based on PVP/PVA incorporated AgNO3

“…It also demonstrates how the crystalline peaks, which are extremely apparent in the PVP/PVA blend, decrease and eventually disappear at maximum loading when the AgNO 3 salt concentration rises. This validates the previous study's discovery that the addition of AgNPs reduced the crystallinity of the materials under study [28,43,44]. This broadening and decrease in intensity is caused by the disruption of the hydrogen bond between the hydroxyl and amino groups in PVP/PVA nanocomposite [43,45].…”

“…The existence of these peaks, associated with the (111) plane, indicates that the AgNPs possess a face-centered cubic (FCC) crystalline structure. This information aligns with prior research that references the (JCPDS file number 04-0783) [37,43,44,51,52]. When transition metal salt is added to polar polymers, charge transfer complexes are formed in the host lattice, which reduces the band gap energy [43,53,54].…”

“…The XRD pattern of FCC Ag nanoparticles shows distinct peaks at 2θ positions around 38.09, 44.33, 64.43, 77.41, and 81.63, which correspond to the (111), (200), (220), (311), and (222) Miller indices, respectively. These peaks confirm the face-centered cubic crystalline structure of the Ag nanoparticles [ 37 ]. The intensity and sharpness of these peaks can indicate the degree of crystallinity and the size of the Ag nanoparticles.…”

“…17,18 The highest intensity of the diffraction peak at the (200) plane indicated the face-centered cubic (fcc) crystal structure of NCP, which suggested a stable NCP structure. 19 There were no obvious changes after PANi coating, as the amorphous PANi only showed a wide bump at around 26°. 20 Notably, the intensity of the above characteristic peaks of NCP@PANi was significantly reduced after PANi coating.…”
