摘要：
Low-temperature (20—400 °C) exoemission of negative charges from mixed oxides having the perovskite structure M1M2O3 (M1 = La; M2 = Co, Mn, Ni) or the spinel structure M1M22O4 (M1 = Cu; M2 = Fe, Co, Cr) was studied. The relationship between the catalytic activity in CO, ethylbenzene, and propylene oxidation and the emissivity of the oxides was elucidated. The role of weakly bound oxygen and variable-valence ions in the exoemission and redox catalysis by mixed oxides is discussed.
