alpha-Fe2O3/BiFeO3(BFO) composites have been prepared by loading alpha-Fe2O3 onto the surface of BFO via a two-step hydrothermal method. The composites have been systematically investigated by X-ray diffraction (XRD) technique, field emission scanning electron microscopy, energy dispersive ...

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 ...
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...
Phosphorous-doped Ti-Fe mixed oxide (P-TiO2-alpha Fe2O3) catalysts were prepared by the microwave-assisted sol-gel route and characterized using XRD, SEM, N-2 physisorption, UV-vis diffuse reflectance, FTIR, and XPS. P-TiO2-alpha Fe2O3 was evaluated during the degradation of a sulfonamide...
Structural study (XRD) revealed the single-phase hematite nanoparticles formation with trigonal alpha-Fe2O3 structure. Morphological study (SEM) confirms silkworm chrysalis shape like morphology by many interconnected nanoparticles of the average size of 30 nm. The electrochemical study indicates that ...
