Fabrication of Mn_2O_3 Nanowire with Ultra Fine Morphology via An Electrospinning Technology

摘要

Thin Mn_2(NO_3)_2/PVA precursor nanowire was fabricated via electrospinning technology at a low temperature in this paper. After dried at 150°C for 10 hours and then sintered at 450°C for 2 hours, Mn_2O_3 nanowire was successfully obtained. The nanowire was characterized using X-ray diffraction and scanning electron microscopy. The results showed that the nanowire was composed of pure Mn_2O_3 phase. The nanowire exhibited smooth surface and continuous sharp with length of tens of micrometer. The diameter of Mn_2O_3 nanowire was measured and calculated through SEM, which showed most probable value of about 110 nm and 270 nm. The reason of the diameter separation was also discussed.
