nanostructures was fabricated using a simple two-step process called the electrospinning
technique and hydrothermal process. A high density of α-Fe2O3 nanorods (about 200 nm in
diameter) was uniformly deposited on a TiO2 nanofibers backbone. The phase purity,
morphology, and structure of hierarchical heterostructures are investigated by X-ray
diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission …
