Facile and sustainable synthesis of shaped iron oxide nanoparticles: effect of iron precursor salts on the shapes of iron oxides.

Sayed FN, Polshettiwar V - Sci Rep (2015)

Bottom Line: Notably, all the six shapes of iron oxides can be synthesised using exactly same synthetic protocol, by simply changing the precursor iron salts.Several of the synthesised shapes are not reported before.This novel protocol is relatively easy to implement and could contribute to overcome the challenge of obtaining various shaped iron oxides in economical and sustainable manner.

ABSTRACT
A facile and sustainable protocol for synthesis of six different shaped iron oxides is developed. Notably, all the six shapes of iron oxides can be synthesised using exactly same synthetic protocol, by simply changing the precursor iron salts. Several of the synthesised shapes are not reported before. This novel protocol is relatively easy to implement and could contribute to overcome the challenge of obtaining various shaped iron oxides in economical and sustainable manner.

Mentions: MW-assisted hydrothermal heating of Fe(II) D-gluconate dehydrate yielded dark black colored product. However, after subsequent washings with water and alcohol, the color quickly turns to greenish yellow. The as-prepared sample (Fe-5-asp) showed almost spherical porous structures (Fig. 7a-b). Some of the incompletely grown and broken spherical particles suggest that these particles could be hollow at the core. However, these spherical porous particles are agglomerated and could not be separated even after several modifications in reaction conditions (temperature, time, stoichiometry etc.). The average size obtained from SEM micrographs was ~150 nm, with a small inhomogeneity in the shape and size. The XRD pattern (Fig. 7c) revealed the amorphous nature of Fe-5-asp sample.
