ABSTRACT: Ferric oxides have drawn significant interest due to their unique properties, relatively low cost,
and due to their potential applications in different fields. In this work, cobalt (Co) doped iron oxide
(Fe2O3) powders, with crystalline size 36.97 nm were successfully prepared using a microwave-
hydrothermal process for the first time and characterised using different techniques. The
morphology of the samples was characterised by scanning electron microscopy (SEM), transmission
electron microscopy (TEM), energy dispersive analysis of X-ray spectroscopy (EDAX), Fourier
transform infrared (FT-IR) spectroscopy and ultraviolet-visible (UV-Vis) spectroscopy. The images
show monodispersed particles with a sharp-edged square morphology. It was found that the average
size was about 33.3 nm for Fe2O3 and 36.97 nm for Co-Fe2O3. The Co atomic percentage dopants
were approximately 5.73%. The nanosized synthesised materials in this study may find an
application in the areas of removal of toxic metal and dyes research.
