摘要：
Oxygen permeable membranes of perovskite crystals with Ba1.0Co0.7Fe0.2Nb0.1O3-delta (BCFN) composition coated with a noble metal catalysts supported by a layered Mg-Al compound (MgAlOx) are demonstrated to provide very high and stable oxygen permeation fluxes. In reactions 300 h in duration, the oxygen permeation flux of this membrane remains greater than 20 mL/ (cm(2) min). This is the first report of such performance over reactions in 300 consecutive hours.
