Fabrication and Characterization of Mg0.6Ni0.4O Hollow Nanofibers by Electrospinning

Mg0.6Ni0.4O hollow nanofibers with diameter of 300-600 nm were successfully prepared by elecrospinning a precursor mixture of polyacrylonitrile (PAN)/(magnesium nitrate+ nickel nitrate), followed by calcination treatment of the electrospun polymer/inorganic composite fibers. The resulting Mg0.6Ni0.4O hollow nanofibers were characterized with X-ray diffraction, Brunauere-Emmette-Teller, FT-IR spectra and scanning electron microscopy. Mg0.6Ni0.4O hollow nanofibres were obtained after being calcined at 500 degrees C and their surface became coarse with increasing of calcination temperatures. Possible formation mechanism for Mg0.6Ni0.4O hollow nanofibers was preliminarily proposed.
