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