Carbon nanofibers (CNFs) have recently received growing attention due to the remarkable characteristics such as their unique physical, chemical, electrical, and electrochemical properties. Among various synthetic methods for fabricating CNFs, an electrospinning method is one of the most popular methods because of advantages such as simplicity, low-cost, and large-scale productivity. In particular, CNF composties have received considerable attention because of various applications such as energy conversion devices, electronic devices, and catalysts. Therefore, CNF composites, such as SnO2 and SiO2 nanoparticles-distributed CNFs, were successfully fabricated. In order to investigate their morphology and structural properties, the weight ratio of the SnO2 and SiO2 nanoparticles to the CNFs was controlled during co-electrospinning. The surface morphology, structure, and chemical binding states of all the samples were carried out by scanning electron microscopy (SEM), transmission electron microscopy (TEM) with energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). These results relative to well-distributed SnO2 and SiO2 nanoparticles in CNFs will be discussed in Conference in detail. |
