The Preparation and Structure Characterization of Nano-Alumina Fiber Doped Cerium by Electrospinning

Abstract:

Alumina fiber, a kind of inorganic fiber, was widely used in many fields owing to its excellent performance. CeCl₃/AlCl₃/PVP was used as spinning solution for producing organic-inorganic hybrid fiber by electrospinning, then, alumina fiber doped cerium can be successfully obtained after high temperature calcination. In the paper, the influence of CeCl₃ to the crystallization and thermal stability was discussed. The results show that alumina nanofiber with average diameters of 200nm-800nm are obtained by calcination of the as-prepared fibers .The addition of CeCl₃ significantly delay the crystallization transformation process of alumina fiber, while the formation of CeO₂ reduce diffusion rate of Al3+, eventually, imped the phase transformation of Al₂O₃ and improve its thermal stability.
