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 ...
By utilizing the magnetron sputtering method, the In2O3/alpha-Fe2O3 films were prepared when the In concentration exceeded its solubility in alpha-Fe2O3 matrix, which was confirmed by the XRD and TEM analysis. The dependence of charge separation on heterojunction structure was evidenced by ...
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...
XRD analysis indicates that all the samples possess a hexagonal structure with anti-ferromagnetic alpha-Fe2O3 phase. The values of lattice parameters and cell volume found to be increased with increasing the cobalt-zirconium substitution along with the amount of alpha-Fe2O3 phase. Crystal symmetry...

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 ...
The products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (I-ESEM), UV-vis diffuse reflectance spectra (UV-vis DRS) and N-2 adsorption/desorption. Photocatalytic activity of the as-prepared alpha-Fe2O3/ZnO composites was evaluated by degradation of ...
XRD, SEM, TEM and EDS analyses indicated that their diameters and lengths were similar to 40 nm and 0.35-1.2 mu m, respectively, in which the largest thickness of ZnO shells was about 10 nm. The heteronanostructures exhibited a dramatic improvement in ethanol sensing characteristics compared to...
