- Title
Morphology Transformation of Hematite Nanoparticles Through Oriented Aggregation.
- Authors
Lili Wang; Lian Gao
- Abstract
Hematite nanoparticles 30–45 nm in width and 15–25 nm in thickness were synthesized through oriented aggregation by a hydrothermal method. X-ray diffraction, transmission electron microscopy, high-resolution TEM, selected area electron diffraction, field emission scanning electron microscopy, and Fourier transform infrared spectroscopy analyses were applied to characterize the nanocrystals. Morphology transformation of these hematite nanoparticles from irregularly shaped to flower like with the assistance of oleic acid was surveyed. Based on these results, possible formation mechanism of the hematite nanoflowers is discussed here.
