Abstract
In this study, we successfully fabricated PtRu/Ru core–shell nanowires (NWs) prepared from as-spun Ru/Pt core–shell NWs via a co-electrospinning method. Their formation mechanism together with the structural characteristics, morphology, and composition of the resulting PtRu/Ru core–shell NWs was elucidated by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM) with energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). PtRu/Ru core–shell NWs fabricated from as-spun Ru/Pt core–shell NWs were formed as a result of interdiffusion between Ru atoms and Pt atoms during calcination after co-electrospinning.
