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...
In this work, we present the magnetic and structural properties of alpha-Fe2O3 nanoparticles synthesized by the hydrothermal synthesis method. XRD, FTIR and Raman spectroscopy indicate that the samples consist of single-phase alpha-Fe2O3 nanoparticles. A microstructural analysis by TEM and SEM ...
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 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 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...
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 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 ...
The phase stability of maghemite nanocrystals was examinedin situunder laser irradiation by Raman spectroscopy and compared with that resulting from heat treatment by X-ray diffraction. It was concluded that ε-Fe2O3is an intermediate phase between γ-Fe2O3andα-Fe2O3and a series of distinct ...
