Significance

The multiple types of efficient oxygen transport paths were demonstrated in high-mechanical-strength hepta-bore Ba0.5Sr0.5Co0.8Fe0.2O3-δ hollow fiber membranes. These types of paths play a prominent role in enhancing oxygen permeation fluxes (17.6 mL min−1 cm−2 at 1223 K) which greatly transcend the performance of state-of-the-art Ba0.5Sr0.5Co0.8Fe0.2O3-δ hollow fiber membranes, showing a good commercialization prospect. © 2017 American Institute of Chemical Engineers AIChE J, 63: 4273–4277, 2017
