Binary Ce-Zr (CZ), Pr-Zr (PZ) and ternary Ce-Zr-Pr (CZP) mixed oxides were prepared by an ammonia-aided co-precipitation method, and were aged in a steam/air flow at 1050 °C. X-ray diffraction (XRD), Raman spectra, X-photon spectra (XPS) and CO temperature programmed reduction (TPR) were carried out to characterize the micro-structure and reducibility of catalysts. The oxygen storage capacity (OSC)...
Luminescent properties of Y 2 O 3 and LaAlO 3 nanopowders doped with Pr 3+ ions and PMMA-based composite materials doped with these powders were reported. The set of active nanopowders differing in praseodymium ions concentration was prepared using sol-gel method and carefully characterized with respect to emission properties in the visible spectral range. In particular,...
