Studies on the Self-arrangement of β-FeOOH Nanowires and the Formation Mechanism

Abstract

Abstract:

β-FeOOH nanowires were synthesized via hydrolysis of iron(Ⅲ) salts at room temperature. The morphology and structure of as-prepared sample were investigated by Transmission Electron Microscopy(TEM) and X-ray Diffraction(XRD). The characterization results showed that the nanowires were well-crystallized tetragonal β-FeOOH nanowires growing along ［001］ axis with diameters about 60 nm and lengths up to 4_5 μm respectively. The formation mechanism of the nanowires was also proposed based on the results of experiment. Moreover,the nanowires can arrange perpendicularly or abreast together to form special patterns through self\|assembly,which the magnetic interaction between them should be the main causation.
