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 chemical composition, material structure, acid-base properties, and structure-activity relationship of (alpha-Fe2O3)(1-x)(V2O5)(x) catalysts were systematically analyzed by the techniques of XRD, XPS, TEM, N-2 adsorption-desorption, Raman, UV-Vis, ESR, NH3/CO2-TPD and Pyridine-IR. ...
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?
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 analysisFESEM analysisOptical propertiesPhotoelectrochemical propertiesThis work proposes a new strategy to prepare a hematite (alpha-Fe2O3) bilayer photoanode by hydrothermally depositing alpha-Fe2O3 (B) on the alpha-Fe2O3 (A) films prepared by electrochemical deposition. Compact smooth surface...
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 ...
