[ 1 ] - Solid state synthesis, crystal structure, evaluation of direct and indirect band gap energies and optimization of reaction parameters for As2Ni3O8 nanomaterials
Nanostructured As2Ni3O8 samples were synthesized via facile solid-state reactions at 850 and 950 °C for 8h using As2O3, Ni(CH3COO)2.2H2O and Ni(NO3)2.6H2O raw materials. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique and fourier-transform infrared (FTIR) spectroscopy. The rietveld analyses showed that the obtained materials were crystallized well i...

[ 4 ] - Pure and Gd3+, Tb3+ and Ho3+-doped As2Ni3O8: A new visible light induced photocatalyst for the photodegradation of malachite green water pollutant
Nanostructured doped As2Ni3O8 samples were synthesized via facile one step solid state reactions at 850 °C for 8 h using As2O3, Ni(NO3)2.6H2O, Gd2O3, Tb2O3 and Ho2O3 raw materials. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique. The rietveld analyses showed that the obtained materials were crystallized well in monoclinic crystal structure with the ...
[ 5 ] - Photocatalytic degradation of water pollutant dye by solid state synthesized Ni1-xLnxSb2O6 (Ln=Eu, Gd, Ho and Yb) nanocomposites
Nanostructured Ni1-xLnxSb2O6 (Ln = Eu, Gd, Ho and Yb) powders were synthesized via stoichiometric 1:2 Ni:Sb molar ratio by solid state reaction at 800 ºC for 8 h using Ni(NO3)2, Sb2O3, Eu2O3, Gd2O3 and Ho2O3 raw materials. The synthesized materials were characterized by X-ray diffraction (XRD) technique. Structural analyses were done by FullProf program employing profile matching with constant ...
