Abstract:

Perovskite structure LaFeO3 Micro-nanofiber was successfully fabricated via electrospinning combined with sol-gel technology. The samples of LaFeO3 micro-nanofiber were characterized by thermogravimetry-differential thermal analysis(TG-DTA), X-ray diffraction(XRD), Fourier transform infrared(FTIR), X-ray photoelectron spectroscopy(XPS) and field emission scanning electron microscopy(FE-SEM) technology, respectively. The results show that the perovskite structure LaFeO3 crystals begin to form at 390 ℃, accompanied by a small amount of weak La2O2CO3 and Fe2O3 hybrid, the orthogonal perovskite structure LaFeO3 micro-nanofiber is obtained by calcining at 600 ℃, the distribution of fiber diameter is between 300 and 600 nm, the average fiber diameter is about 420 nm with an average grain size of 28 nm.
