In the present work, extensive study of ionic conductors with pyrochlore and fluorite structure in Gd2O3–HfO2 system are carried out. Gd2Hf2O7 Gd2.1Hf1.9O6.95, Gd2.16Hf1.84O6.92, Gd2HfO5 solid solutions known...
The phase formation of samarium tungstate Sm2WO6 from a mechanically activated oxides mixture Sm2O3:WO3 = 1:1 has been studied using thermal analysis methods; microstructure the powder samples and...
The design of new oxygen- and proton-conducting materials is paramount importance for their possible utilization in solid oxide fuel cells. In the present work, La2(Hf2–xLax)O7–x/2 (x = 0, 0.1) ceramics were prepared using ball milling mixtures (La2O3 HfO2) followed by high-temperature annealing at 1600 °C 10 h air. La2Hf2O7 exhibit an ordered pyrochlore-type structure, whereas La2(Hf1.9La0.1)O6.95 has a defect pyrochlore structure type with oxygen vacancies 48f positions. ion proton...
We report a study of nanophases in the La2O3–MO3 (M = Mo, W) systems, which are known to contain variety good oxygen-ion and proton conductors. Mechanically activated La2O3 + MO3 mixtures final ceramics have been characterized by differential scanning calorimetry (DSC) X-ray diffraction (XRD) with Rietveld refinement. The microstructure materials has examined electron microscopy (SEM), their conductivity dry wet air determined using impedance spectroscopy. In both formation hexagonal...
An effect of Cu powder dispersion and morphology on the surface structure physical–chemical catalytic properties Cu–CeO2 catalysts prepared by mechanochemical synthesis was studied in preferential CO oxidation a H2-rich stream (CO-PROX). Two catalysts, produced 30 min ball-milling from CeO2 8 mass% copper powders with particle sizes several tens (dendrite-like Cu) 50–200 nm (spherical obtained levitation-jet method), respectively, were characterized X-ray diffraction electron microscopy...
