Abstract

We reported the scalable production of iron oxide nanowhiskers from 250 mL laboratory scale to 10 L reactor reaction. During the scale-up process, the reaction time was found to be a critical parameter to adjust for the production of iron oxide nanowhiskers with similar quality to that of the laboratory scale. Based on transmission electron microscopy and magnetometry analysis, the size, size distribution, and magnetic properties of the large scale products were comparable to those produced on laboratory scale. Subsequently, these nanowhiskers were transferred from organic solvents to aqueous solution using a 38-liter stainless steel tank. These water soluble nanowhiskers were well dispersed in water and the surface chemistry was confirmed by Fourier transform infrared spectroscopy.
