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.

f5: (a-b) SEM of as-prepared distorted cubes (Fe-3-asp) (c) XRD pattern of distorted cubes; as-prepared and after different heat treatments.

Mentions: The SEM images of as-prepared sample from FeCl3.6H2O as precursor are shown in Fig. 5(a-b). The sample consists of mostly distorted cubes along with the very small fraction of secondary shapes. The estimated average size as visible from SEM is ~120 nm. On phase characterization using XRD, the sample revealed to be consisting of pure α-Fe2O3 (Fig. 5c). The peaks matches well with the reported standard pattern of α-Fe2O3 (PCPDF 33-0664).
