摘要
Continuous LaFeO3 nanowires and nanobelts were successfully synthesized using a sol-gel assisted electrospinning method followed by calcination at 500 degrees C in air. The thermal decomposition processes of LaFeO3 are carefully investigated and the best calcining temperature was found to be 500 degrees C. The two nanofibers obtained were characterized using X-ray diffraction analysis, which shows single phase and the structure of nanobelts has higher crystallinity than that of the nanowires. The scanning electron microscopy reveals that the diameter of the obtained LaFeO3 nanowires is 139.3 nm. And the thickness and width of the nanobelts are 80 and 459 nm. Moreover, the electrospun LaFeO3 nanobelts are endowed with a higher specific surface area compared with the nanowires, which results from the regular one dimensional morphology without any detectable agglomeration and a rough surface.
