A Sustainable Approach to Fabricating Ag Nanoparticles/PVA Hybrid Nanofiber and Its Catalytic Activity

Abstract

Ag nanoparticles were synthesized by using Ficus altissima Blume leaf extract as a reducing agent at room temperature. The resulting Ag nanoparticles/PVA mixture was employed to create Ag nanoparticles/PVA (polyvinyl alcohol) hybrid nanofibers via an electrospinning technique. The obtained nanofibers were confirmed by means of UV-Vis spectroscopy, The X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and then tested to catalyze KBH4 reduction of methylene blue (MB). The catalytic results demonstrate that the MB can be reduced completely within 15 min. In addition, the Ag nanoparticles/PVA hybrid nanofibers show reusability for three cycles with no obvious losses in degradation ratio of the MB.

Green Synthesis of an Activated Carbon-Supported Ag and ZnO Nanocomposite for Photocatalytic Degradation and Its Antibacterial Activities

“…To further confirm the formation of AgNPs and ZnONPs X-ray diffraction patterns of the two samples were collected and are shown in The XRD results clearly show that the AgNPs and ZnONPs prepared by the Neem extract are both crystalline in nature. The crystallite size of AgNPs and ZnONPs were calculated by the Debye-Scherer's equation [47]:…”

“…Many plant products such as Azadirachta indica (Neem) leaf extract [38,44,45]. Tribulus longipetalus extract [40], Acacia nilotica pods [46], Ficus altissima Blume leaf extract [47], and aqueous leaf extracts of Emblica officinalis [42], are capable of reducing metal ions to nanoparticles because of their antioxidant properties. Furthermore, plant extracts produce capping agents for the stabilization of nanoparticles.…”

“…4k, l) were indexed to lattice planes of Bragg’s reflection: diffraction peaks of (111), (200), (220), and (311) planes suggested that DH-AgNps and DH-AuNps were face-centered cubic and primarily composed of (111) orientation [4, 24]. The assigned peaks denoted by * at 27.89°, 32.33°, and 46.33° (2θ) (Fig.…”
