你好，我想请问一下，是如何判断FeOOH是α―FeOOH，β―FeOOH，还是λ―FeOOH 发自小木虫Android客户端...
The morphology and structure of the final products were investigated in detail by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and selected area electron diffraction (SAED). The probable formation mechanism of the alpha-FeOOH and alpha-Fe_2...
XRD57Fe MössbauerFT-IRFE SEMEDSThe influence of ruthenium ions on the precipitation of alpha-FeOOH, alpha-Fe2O3 and Fe3O4 in highly alkaline media was investigated by 57Fe Mssbauer and FT-IR spectroscopies, thermal FE SEM and EDS. The presence of Ru-dopant strongly affected the ...
The XRD analysis of the samples precipitated in the presence of Zn 2+ ions showed the formation of solid solutions of α-(Fe, Zn)OOH up to a concentration ratio r = [Zn]/([Zn] + [Fe]) = 0.0909. ZnFe 2O 4 was additionally formed in the precipitate for r = 0.1111, whereas the...
The XRD analysis of the samples precipitated in the presence of Zn~(2+) ions showed the formation of solid solutions of alpha-(Fe, Zn)OOH up to a concentration ratio r=[Zn]/([Zn] + [Fe]) = 0.0909. ZnFe_2O_4 was additionally formed in the precipitate for r = 0.1111, whereas ...
The pigment obtained was analyzed by XRD, color reader and scanning electron microscopy (SEM). The structure crystal of pigment at all variation of pH and calcinations temperature were hematite (a-Fesub2/subOsub3/sub) with good crystallization and聽 relatively pure. The color of pigment ...
Structural, optical, morphological, and electrochemical characterization was performed by XRD, UV-Vis spectroscopy, FE-SEM, and electrochemical impedance. In both cases, the monoclinic phase of BiVO4 was correctly coupled to each material. In all cases, a decrease in band gap was observed compared...
The obtained samples were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) analysis, N-2 adsorption-desorption (BET), and X-ray diffraction (XRD). SEM images showed that the modification of phosphate had no major changes on the morphology of the original ...
Phase and morphology of the products are investigated using XRD, FTIR, SEM, and TEM analysis. Using UV-Vis spectra, various electronic transitions of goethite and maghamite particles are examined. Maghamite nanostructures exhibit superparamagnetic property at room temperature. On the basis of ...
X-ray powder diffraction (XRD) and high-resolution TEM (HRTEM) studies indicated that nanowires were single-crystalline with an oriented growth along the [1 3 0] direction. The effects of Cu-dopant content on the morphologies and crystalline phases characterized by field emission scanning electron...
