摘　　要：　通过无机铁(Ⅲ)盐的水解在常温条件下制备了β-FeOOH纳米线,并用透射电子显微镜(TEM)、高分辨透射电镜(HRTEM)、X射线衍射(XRD)及选区电子衍射(SAED)对其形貌及结构进行了表征.电镜结果表明,所得到的纳米线直径约60nm,长度为4-5μm,且沿[001]方向生长.XRD结果表明纳米线为四方相β-FeOOH,在常温下结晶性良好.研究表明FeCl3浓度对纳米线生长有很大影响,只有当FeCl3浓度合适时,才能制备出高质量的纳米线.β-FeOOH nanowires were synthesized via hydrolysis of iron(Ⅲ) salts under room temperature. The morphology and structure were characterized by transmission electron microscopy, high-resolution transmission electron microscopy, X-ray diffraction, and selected area electron diffraction. The results showed that the nanowires were tetragonal lattice with the diameter of about 60 nm and the length of 4-5 μm respectively, and grew along [001] axis. It was found that the concentration of FeCl3 solution could extremely affect the growth of β-FeOOH nanowires and only under appropriate concentration high quality nanowires could be obtained.
