- Abstract
- A layer consisting of La0.6Sr0.4CoO3-delta particles with inner nano-pores is coated on the La0.7Sr0.3Ga0.6Fe0.4O3-delta oxide to improve the surface reaction resulting in high oxygen permeability. The La0.6Sr0.4CoO3-delta particles with inner nano-pores are synthesized by an ultrasonic spray pyrolysis method. The permeated oxygen contents from air to helium gas were measured using gas chromatography after the synthesized particles were coated on the La0.7Sr0.3Ga0.6Fe0.4O3-delta oxide by the conventional screen-printing. The results demonstrated that the reactive free surfaces of the nano-pores are an important factor in determining the oxygen permeation for application such as gas separation membrane and ceramic fuel cell.
