초록

Nickel oxide nanofibers were synthesized by electrospinning with nickel(II) acetate tetrahydrate and polyvinylpyrrolidone and calcination process. The nanofiber shape was easily detected from the nanofibers with high Ni contents after calcined at $600^{\circ}C$ and the crystal structure of layer-by-layer growth was observed from SEM images at $900^{\circ}C$. XRD and TEM results showed metallic Ni and NiO structure were formed at nanofibers obtained at 600 and $900^{\circ}C$ and the crystallite size was calculated from 25 to 55 nm. The surface of nanofibers was fully oxidized from the deconvoluted Cu 2p and O 1s XPS spectra.
