Abstract
In this research we report a one-step method to fabricate Fe2O3/C microspheres by using the rolling scales oxides via the solvothermal approach. The thermal gravimetric Analysis (TGA) experiment was carried out in order to determine the amount of carbon in the synthesized samples. Only Fe2O3 peaks could be observed from X-ray diffractometry patterns; the carbon in the composite was amorphous. The content of the carbon in the composite was calculated to be about 72 wt %. After annealing at 800°C, scanning electron microscopy images showed that the surface of microspheres was rather smooth and their diameters were in the range of 1–3.5 µm. The investigation of Fe2O3/C microspheres formation mechanism revealed that Fe2O3 nanoparticles are homogeneously distributed in the carbon matrix.
