静电纺中空NiO/C纳米纤维的制备及中空形成机理分析
Preparation of hollow NiO/C nanofibers and analysis of mechanism of hollow formation
摘要
Abstract
For the preparation of NiO and carbon nano hollow fiber, PAN and Ni (CH3COO)2·4H2O were used as precursor to prepare NiO/C hollow composite nanofiber by using electrospinning technique and kirkendall effect. The effect of oxidation time on the composite structure was investigated, and the optimum oxidation time was determined. And X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) were used to characterize the the material. The results show that oxidation time of 2 h at 300℃is the optimum choice, a large number of NiO hollow nanoballs (size of about 16 nm and shell thickness of about 4-5 nm) uni-formly distributed in the interior and on the surface of the fibers with average diameter of 180 nm. The phasic and morphology evolutions that related to the heating time confirm that the formation of NiO hollow nanoballs is driven by Kirkendall effect.关键词
