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,...
detail by various techniques such as X-ray diffraction pattern, field emission scanning electron microscopy (FESEM) combined with energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM) equipped with high-resolution TEM, Fourier transform infrared (FTIR) and Raman-scattering ...
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 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 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 composition, morphology and structure of alpha-Fe2O3 containing PVDF nanofibers mats were investigated by SEM, XRD, Raman, FTIR, XPS and DSC. Studies have shown that the inclusion of alpha-Fe2O3 nanoparticles promotes additional crystallization and self-polarization of PVDF into an ...
The NIO was characterized by the Raman spectroscopy method. The degradation pathways and the formation of degradation products were studied. A high-pressure mercury lamp and sunlight were employed as light source. Fenuron photodegradation using NIO with oxalic acid followed the pseudo-first-order ...
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...
