Title: A simple route to disperse silver nanoparticles on the surfaces of silica nanofibers with excellent photocatalytic properties

Abstract

Graphical abstract: The SiO{sub 2}/Ag composite nanofibers have been prepared by electrospinning and thermal decomposition of hybrid nanofibers, which exhibit a good catalytic property in reducing the methyl orange dye. Highlights: ► Hydrochloric acid was used as the catalyst of tetraethyl orthosilicate. ► Silver nanoparticles are obtained by pyrolysis of silver chloride. ► PVP–silica hybrid can disperse silver chloride and thus preventing the aggregation of silver nanoparticles. ► The catalytic activity of SiO{sub 2}/Ag composite nanofibers is much larger than that of SiO{sub 2} nanofibers. -- Abstract: In this work, monodispersed silver nanoparticles decorated SiO{sub 2} nanofibers were synthesized by electrospinning method, followed by thermal treatment at 600 °C. Powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermo-gravimetric analysis (TGA) and X-ray photoelectron spectroscopy (XPS) were used to characterize the composite nanofibers. Accordingly, the detailed formation mechanism of SiO{sub 2}/Ag composite nanofibers was discussed. Furthermore, an excellent catalytic activity of SiO{sub 2}/Ag composite fibers was observed by a degradation reaction of methyl orange (MO) dye.
