The new potassium–bismuth–nickel oxophosphate obtained by hydrothermal synthesis in the Bi(OH)3–NiCO3–K2CO3–K3PO4 system is studied by X-ray diffraction, IR spectroscopy, and Raman spectroscopy. Parameters of the orthorhombic cell are as follows: a = 13.632(1) , b = 19.610(2) , ...
The physical properties of α-Na2Ni2Fe(PO4)3 were studied by magnetic and electrochemical measurements and by Mssbauer and Raman spectroscopy. α-Na2Ni2Fe(PO4)3 crystallizes according to a stuffed α-CrPO4-type structure with the space group Imma and the cell parameters a = 10.42821(12), ...
The samples were investigated by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) spectroscopy, scanning electron microscopy (SEM), Raman spectroscopy, and electrochemical methods. The XRD patterns of Li_(2.5)Na_(0.5)V_((2-2x/3))Ni_x(PO_4)_3/C are in good agreement with...
Raman spectra of Na3AZr(PO4)3 (A=Mg, Ni) phosphates present broad peaks in favor of the statistical distribution in the sites around PO4 tetrahedra. Diffuse reflectance spectra indicate the presence of octahedrally coordinated Ni2+ ions.
TiO2的引入使得钨物种趋向于以多核聚钨酸WO3形式存在;镍,钨物种在TiO2改性的复合载体上更容易被还原,有利于催化剂的硫化.%Titania modified A1PO4-5/A12O3 composite support was prepared by adding metatitanic acid to AlPO4-5/Al2O3 and a series of catalysts with various TiO2 content were prepared ...
