Nickel nanostructures prepared by various methods have received considerable attentions due to their numerous applications. In this study, one-dimensional nickel nanowires (NiNWs) were synthesized by the reduction of nickel (II) chloride in polyol medium. Polyvinylpyrrolidone (PVP) served as the surfactant and hydrazine hydrate was used as the reductant. | Effects of synthesis conditions on structure of nickel nanowires prepared by reduction method
