The double perovskite yttriated zirconia and a catalytic system for activating oxygen at remarkably low temperatures.
Researchers from the Institute of Chemistry of Poitiers environments and materials (CNRS / Université de Poitiers) and the Research Institute of Catalysis and Environment Lyon (CNRS / Université Lyon 1) demonstrated that activation of O2 on the surface of a yttria-stabilized zirconia (YSZ) was greatly facilitated by the presence of a perovskite LaMnO3 without requiring contact between the two materials. This results in a phenomenon of exchange between the gaseous oxygen and the oxygen atoms of the solid YSZ from 300 ° C. This property is one of the double compound of LaMnO3 and YSZ an extremely efficient catalyst system for the transformation of methane. These results are published in the journal Angewandte Chemie International Edition.
