Facile Method to Prepare Metal Sulfide(Ag_2S,CuS,PbS) Nanoparticles Grown on Surface of Polyacrylonitrile Nanofibre and Their Optical Properties
Polyacrylonitrile-metal sulfide nanocomposites with metal sulfide(Ag2 S,CuS,PbS) nanoparticles homogeneously dispersed on the polyacrylonitrile(PAN) nanofibre were synthesized by means of electrospinning technology combined with gas-solid reaction.A series of experiments was performed to characterize the morphology variation and distribution of the nanocrystalline.The result shows that the concentration of metal salt aqueous solution affects the size and morphology of metal sulfide nanoparticles during the chelating process.Further more,these metal ions nanoparticles were attached to the surface of the nanofibre homogeneously through chelating effect which will be propitious to prevent nanoparticles from aggregation.These results suggest that the method reported here is extremely effective for synthesizing PAN-metal sulfide nanocomposites which have good visible light photocatalytic activity.Further more,this method could be extended to prepare other PAN-metal halides nanocomposites,too.
