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. View Full-Text
