    Nanometer sized tantalum pentoxide fibers prepared by electrospinning
    摘要:
    Novel, porous tantalum pentoxide (Ta2O5) nanofibers with 150-250 nm diameter were obtained by high temperature calcination of the as-electrospun tantalum pentoxide/poly(vinyl acetate) (PVAc) composite fibers prepared by sol-gel processing and electrospinning technique. Surface analysis, structure and elemental composition of these as-electrospun and as-calcinated Ta2O5 nanofibers have been studied by scanning electron microscope (SEM) equipped with an energy dispersive X-ray analysis (EDX), high resolution field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), X-ray diffraction patterns (XRD) and FT-IR. High-resolution FE-SEM images showed the porous nature of Ta2O5 nanofibers. EDX analysis revealed the perfect stoichiometry of the nanofibers as Ta2O5. A linear correlation was noted between the calcination temperature and orthorhombic crystalline phase evolution of Ta2O5. (c) 2005 Elsevier Ltd. All rights reserved.

  • Oxidation Catalysis of Nb(salan) Complexes: Asymmetric Epoxidation of Allylic Alcohols Using Aqueous Hydrogen Peroxide as an Oxidant
    作者:Hiromichi Egami、Takuya Oguma、Tsutomu Katsuki

    日期:2010.4.28
    Several optically active Nb(salan) complexes were synthesized, and their oxidation catalysis was examined. A dimeric mu-oxo Nb(salan) complex that was prepared from Nb(OiPr)(5) and a salan ligand was found to catalyze the asymmetric epoxidation of allylic alcohols using a urea-hydrogen peroxide adduct as an oxidant with good enantioselectivity. However, subsequent studies of the time course of this
    合成了几种光学活性 Nb(salan) 配合物,并研究了它们的氧化催化作用。发现由 Nb(OiPr)(5) 和 salan 配体制备的二聚体 mu-oxo Nb(salan) 复合物可催化烯丙醇的不对称环氧化,使用尿素-过氧化氢加合物作为氧化剂,具有良好的对映选择性。然而,随后对该环氧化的时间过程以及配体的 ee 与产物的 ee 之间关系的研究表明,mu-氧代二聚体在环氧化之前解离成单体物质。而且,发现由 Nb(OiPr)(5) 和 salan 配体原位制备的单体 Nb(salan) 配合物,然后进行水处理,发现使用过氧化氢水溶液在 CHCl(3)/盐水或甲苯/盐水溶液中更好地催化烯丙醇的环氧化具有高对映选择性,范围从 83% 到 95% ee,除了肉桂醇的反应显示 74% 的中等 ee。这是使用过氧化氢水溶液作为氧化剂对烯丙醇进行高度对映选择性环氧化的第一个例子。
