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 60 nm, 长度为4～5 μm, 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.

Key words: β-FeOOH, nanowire, hydrolysis
