The nanoflakes were characterized by X-ray diffraction, scanning electron microscopy, high-resolution transmission electron microscopy, and Raman spectroscopy. The reversible Li-cycling properties of the alpha-Fe2O3 nanoflakes have been evaluated by cyclic voltammery, galvanostatic discharge-charge cycling,...
The Raman-scattering spectrum of the synthesized nanocubes exhibited several Raman-active modes which further confirmed the formation of pure alpha-Fe2O3. As a functional material, the synthesized alpha-Fe2O3 nanocubes were used as electrode material to fabricate ethanol gas sensor which was tested...

The X-ray diffraction, Raman spectrum and scanning electron microscopy are carried out to characterize the nanobelts and nanoflakes. The formation mechanism has been presented. Significantly, the magnetic investigations show that the magnetic properties are strongly shape-dependent. The magnetization ...
The Raman and FTIR spectra further confirmed the formation of Fe and O vibration modes. The optical reflection edges shifted toward higher wavelength with the increase in reaction temperatures and bandgap decreased from 2.88 to 2.74 eV. The Brunauer-Emmett-Teller results showed that the large ...
The existence of the latter junction is affirmed via XRD, TEM-SAED, Raman and FTIR techniques whereas, the photogenerated charges, their separation together with their transport and recombination rates are depicted via photoluminescence, electrical conductivity, incident photon to current efficiency (IP...
Results from X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) showed that the as-prepared products were pure hematite without any impurity. Transmission electron microscopy (TEM) analyses indicated that the as-prepared...
The α-Fe 2 O 3 -TiO 2 nanomaterials containing different weight percentage (2.5, 5, 16, 25, and 50) of TiO 2 to α-Fe 2 O 3 were characterized using SEM, XRD, UV-Vis, FTIR and Raman techniques, respectively. The electrochemical properties of α-Fe 2 O 3 -TiO 2 nanomaterials ...
The magnetic photocatalyst alpha-Fe2O3/reduced graphene oxide (rGO) was constructed to enhance the photocatalytic efficiency by the magnetic field. The results of X-ray diffraction spectrometer (XRD), Raman and high resolution transmission electron microscope (HRTEM) indicated the successful preparation...
