Abstract

EPR Characterization of (CeO 2 ) 1−y (La 2 CuO 4 )y Oxide Mixtures and Their Catalytic Activity for NO Reduction by CO.-Title compounds with y = 0, 0.17, 0.25, 0.35, 0,43 and 0.50 are prepared by thermal treatment of La 2 O 3 , CeO 2 and CuO in molten NH 4 NO 3 . The interaction among the oxides results in the formation of an La 2 O 3 -CeO 2 solid solution over a wide range of composition. CuO segregation over the surface takes place. The catalytic activity is essentially due to this segregation effect. -(OLIVA, C.; FORNI, L.; EZERETS, A. M.; MUKOVOZOV, I. E.; VISHNIAKOV, A. V.; J. Chem.
