N2 - Asymmetric pore configuration of dual-layer hollow fibre catalyst membrane of NiO-YSZ (inner layer)/La0.7Sr0.3Co0.2Fe0.8O3-δ-YSZ (outer layer) has been studied from its morphology and oxygen transport point of view. The membrane was synthesized by phase inversion method and co-extruded using water as the external coagulant and water, ethanol and NMP mixture as the internal coagulant (bore liquid mixture), followed by sintering at 1300 °C for 8h. Volume ratio of water:ethanol:NMP was 4:1:5. The resulted dual-layer membrane has non-sandwich like pore configuration. SEM images of the membrane showed finger-like pores on the internal side and sponge-like pores on the external side. Bending strength of the membrane was 9.76 MPa and nitrogen permeability (gas tightness) was 1.36 x 10-4 mol.m-2.s-2. Pa-1. The oxygen permeability of the membrane at 600, 700 and 800 °C was 2.78 x 10-8, 2.84 x 10-8 and 3.10 x 10-8 mol.s-1.cm-2, respectively, which is about two order of magnitude lower than oxygen permeability of other reported perovskite-based membranes.
