摘要

The novel Fe/Nb co-doped Ba(Co_0 8Fe_0.1Nb_0.1)O_(3-δ) oxide was synthesized by the solid-state reaction method. Structural, sintering and oxygen sorption properties of the Ba(Co_0 8Fe_0.1Nb_0.1)O_(3-δ)oxide were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetry (TG). The results demonstrate that the structural stability of the Fe/Nb co-doped Ba(Co_0 8Fe_0.1Nb_0.1)O_(3-δ) oxide is improved significantly. The oxygen sorption property of the Fe/Nb co-doped Ba(Co_0 8Fe_0.1Nb_0.1)O_(3-δ) oxide was investigated in air between 300°C and 900cC, and an oxygen sorption capacity of 7.0 mL(STP) O_2/g oxide is obtained.
