The influence of the composition of composites based on Y- and Sc-stabilized zirconia doped with CeO2 and transition metal oxides (Cu, Co, Ni) on catalytic properties in oxidative conversion of methane was studied. Activity of the composites correlates with the quantity and mobility of oxygen in them.

Key word methane oxidation, prototype of anodes, zirconia, yttrium, scandium oxides, transition metal oxides, mobil-
ity of oxygen.
