Abstract :
The spinel NiCo2O4 nanofibers with diameters of 50–100 nm were prepared by high temperature calcinations of a simple inorganic-polymer composite fibers, which were obtained by electrospinning of the PVA/cobalt acetate/nickel acetate composite precursor. The crystallinity, purity, and surface morphology of the as-prepared NiCo2O4 nanofibers were investigated by XRD, FT-IR, SEM, respectively.
