Preparation and Properties of SrFeO_(3-δ)Based Mixed Conducting Membrane Material Doped with Cu and Ti
Source abstract
Abstract
A series of SrFe(Cu,Ti)O3-δmembrane materials were synthesized by a citric acid complex method. The crystal structures and phase stabilities of the materials were studied by TG-DSC and XRD. It is found that Cu and Ti doping content has great effects on the phase component and the oxygen permeability of the materials. The addition of Cu can increase the oxygen vacancy concentration and the addition of Ti can enhance the structure stability. SrFe0.6Cu0.3Ti0.1O3-δhas pure perovskite structure and exhibits high stability and high oxygen permeation flux which is 0.7mL·min-1·cm-2(STP) under air/He gradient at 900℃.
