We investigate the structural and transport properties of Mn doped hematite (alpha-Fe2O3). The X-ray diffraction pattern identifies the single-phase and corundum (Al2O3) type structure of the polycrystalline samples Fe2-xMnxO3 (x = 0, 0.01, 0.10 and 0.50). The resistivity curve shows a ...
The crystal structure was refined to a bixbyite-type cubic structure (Ia (3) over bar) with alpha = 9.4039(1) angstrom by the Rietveld method. Single crystalline beta-Fe2O3 particles of approximately 1 mu m in size were topotactically transformed into single alpha-Fe2O3 crystals. Electron ...
Because of the unique porous structure, the potential application in water treatment of the α-Fe2O3 porous nanorods was investigated. The UV−vis measurements suggest that the a... 展开 关键词: hematite ionic liquid superstructures porous materials magnetic properties ...
The structure of the basal plane of the a phase of Cr2O3 has been investigated using periodic ab initio Hartree-Fock theory. The Cr-terminated surface, which is nonpolar but is charged, is found to be stable. However, a large-scale relaxation of the surface layer away from the ideal bul...
The morphology and interface structure of α-Fe2O3 islands grown on α-Al2O3 single crystals (sapphire) by Fe-ion-implantation and annealing in an oxidizing atmosphere have been studied using transmission electron microscopy. The α-Fe2O3 islands have the orientation relationship of [0001]α-...
The (alpha-Fe2O3)(1-x)(V2O5)(x) catalysts were synthesized by coprecipitation method of Fe and V elements and microwave drying. The chemical composition, material structure, acid-base properties, and structure-activity relationship of (alpha-Fe2O3)(1-x)(V2O5)(x) catalysts were ...

Quasicubic -Fe2O3 nanoparticles embedded in TiO2 thin films grown by atomic layer deposition. Monodispersed quasicubic -Fe 2 O 3 nanoparticles were synthesized from ferric nitrite (Fe(NO 3 ) 3 ), N , N -dimethyl formamide and poly( N -vinyl-2-pyrrol... Tamm,Aile,Seinberg,... - 《...
The alpha-Fe2O3 has shown Rhombohedral (Hematite) crystal structure. Scanning electron microscopy results reveal that the alpha-Fe2O3 thin films have well covered nanoporous surface. The as prepared films exhibited a direct band gap energy varying from 2.36 to 2.14 eV. The alpha-Fe2O3 thin ...
