XRD, TEM and thermal analysis of Fe doped boehmite nanofibres and nanosheets
Frost, Ray L., Zhao, Yanyan, Martens, Wayde N., & Zhu, Huai Yong (2007) XRD, TEM and thermal analysis of Fe doped boehmite nanofibres and nanosheets. Journal of Thermal Analysis and Calorimetry, 90(3), 755 -760.
Iron doped boehmite nanofibres with varying iron content have been prepared at low temperatures using a hydrothermal treatment in the presence of poly (ethylene oxide) surfactant. The resultant nanofibres were characterized by X-ray diffraction (XRD), and transmission electron microscopy (TEM). TEM images showed the resulting nanostructures are predominantly nanofibres when Fe doping is less than 5 %; in contrast nanosheets were formed if Fe doping was above 5 %. For the 3 % Fe doped boehmite, a mixed morphology of nanofibres and nanosheets were obtained. Nanotubes instead of nanofibres were observed in samples with 20 % added iron.
The Fe doped boehmite and the subsequent nanofibres/ nanotubes were analysed by thermogravimetric and differential thermogravimetric methods. Boehmite nanofibres decompose at higher temperatures than non-hydrothermally treated boehmite and nano-sheets decompose at lower temperatures than the nanofibres.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
