Abstract
Perovskite-like manganites La1-xSrxMnO3 (x = 0, 0.3, 1) and chromites La1-x SrxCrO3 (x = 0, 0.2) were synthesized by the cryochemical method. The tempe rature intervals of predominant occurrence of various oxygen exchange react ions at the complex oxide-gas phase interface were determined by the dynami c-thermal isotope exchange method. The influence of the composition of mang anites and chromites on their catalytic activity in oxygen isotope exchange reactions and the oxidation of carbon monoxide and methane is discussed.
