【英文摘要】Rare earth perovskite-typed composite
oxides(ABO3) are new types of inorganic non-metallic materials with stable crystal structure and unique physical and chemical properties. They have drawn more and more attention of
scientists in the field of solid fuel cell, solid electrolyte, sensor and catalysis, especially in photocatalysis.
Electrospinning is a new method for preparation of
nanomaterials and a lot of one-dimensional nanomaterials have been prepared by electrospinning. It is an important and urgent research subject to fabricate rare earth perovskite-type oxides nanobelts via electrospinning technique.In this dissertation, inorganic metallic salts were used as raw
materials, PVP was employed as template and DMF as solvent. PVP/metallic salts composite nanobelts were fabricated by combination of sol-gel and electrospinning.
LaM03(M=Cr,Fe,Mn,Co,Ni,Al) nanobelts were prepared by
calcination of the relevant composite nanobelts at 600℃-800℃The samples were characterized by
thermogravimetric-differential thermal analysis(TG-DTA),
X-ray diffractometry(XRD), scanning electron microscopy(SEM). energy dispersive spectroscopy(EDS) and Fourier transform
