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 ...

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...
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 ...
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 ...
The structural and photoelectrochemical (PEC) properties of the films were characterized by the X-ray diffraction (XRD) technique, Energy-dispersive spectrometer (EDS), X-ray photoelectron spectroscopy (XPS) and water splitting experiment. The film fabricated at 500 degrees C shows the strongest ...
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 prepared samples were characterized by transmission electron microscopy (TEM), Mossbauer spectroscopy, X-ray diffraction (XRD) and differential thermal analysis thermogravimetric analysis (DTA-TGA). The results showed that after 90 h milling alpha-Fe2O3 nanoparticles were obtained, and the particle...
