Abstract

<p>The controlled synthesis and fabrication of nano- and microstructured materials has received much attention over the past decade owing to the unique chemical, electrical, magnetic, and optical properties of nanoscaled materials when compared to the bulk. The most common method for producing iron oxide microspheres has been solvothermal. Some of these procedures require harsh chemicals or expensive surfactants, while other try to minimize the environmental impact of production. The NaOH template is removed in the water bubblers and during subsequent washings leaving highly porous iron oxide spheres. Spray pyrolysis and similar aerosol techniques are well known has scalable synthetic methodologies for the preparation of metal oxide materials from relatively inexpensive precursors.</p>
