In the present work flower-like, alpha-Fe2O3 were synthesized by ethylene-glycol mediated polyol method. The synthesized flower-like, alpha-Fe2O3 were separated cadmium (Cd2+) chromium (Cr6+) and lead ions (Pb2+) from wastewater. XRD pattern and FESEM images show the obtained sample is...
The XRD pattern of hematite α-Fe2O3 nanoparticles were indexed to rhombohedral structure of α-Fe2O3, while the TEM images illustrate the flaky structure of graphene supported by hematite nanoparticles. The rGO/\\(\\alpha\\)-Fe2O3 nanocomposites showed enhanced photocurrent of ~?4?mA cm?

After annealing, all samples revealed only hematite characteristics in XRD pattern and Raman spectra. Thickness of annealed thin films was similar to 350 nm measured via SEM cross-section image. The optical band gap and carrier concentration of samples were in the range of 2.13-2.16 eV and 6.28...
Nanoparticles of alpha ferric oxide (alpha-Fe2O3) were prepared by the hydrothermal method. Structural properties of alpha-Fe2O3 were determined by XRD, SEM and AFM measurements. The particles had a good matching with standard pattern. Average particle size was about 90 nm and the distribution...
The XRD pattern is represented in Figure 4B. The reflection peaks in this pattern were in good agreement with Hem-NPs having the expected rhombohedral geometry (JCPDS-79-1741). Peaks of crystalline α-Fe2O3 NPs were found at 24.12°, 33.1°, 35.6°, 40.54°, 49.52°, 54.08°, 57.46°,...
The XRD pattern of the α-Fe2O3 annealed at 800 °C is shown in Figure 5a. The pattern consists of peaks at 24.42°, 33.40°, 35.86°, 41.12°, 49.68°, 54.32°, 57.86°, 62.64°, and 64.26° corresponding to the (012), (104), (110), (113), (024), (116), (018), (214...
In order to evaluate the crystal phase and degree of crystallinity of the ZnO@α-Fe2O3 NFs in its initial state, the XRD pattern of the catalyst in its as-prepared form was provided. The XRD pattern of the ZnO@α-Fe2O3 NFs is shown in Figure 6A. ZnO@α-Fe2O3 exhibited a strong...
