A series of samples of general formula (CeO2)(1-y)(La2CuO4)(y), with y
= 0, 0.17, 0.25, 0.35, 0.43, 0.50, has been analysed, mainly by EPR.
Catalytic activity was tested for the reduction of NO by CO. The inter
action among the oxides resulted in the formation of an La2O-CeO2 soli
d solution over a wide range of composition. CuO segregation over the
surface also took place, thus enhancing catalytic activity.
