| Research Abstract |
Several resembling CaF_2-like phases could coexist in the Zr-Ce-Pr-O system which were originated from the Zr-Ce-O and Zr-Pr-O systems. When the analogous particles with appropriate compositions are connected coherently by sintering, oxygen deficient-sites may be introduced and on the contrary oxygen intercalation may also occur in the interface region. When optimizing the phenomena, complex oxides involving stable/ metastable phases have demonstrated their potentials as superior reaction fields for exhaust gas catalyst and methane-steam reforming.
