High performance BaBiScCo hollow fibre membranes for oxygen transport†
Abstract
Here we report the production of novel high performance BaBi0.05Sc0.1Co0.85O3−δ (BaBiScCo) hollow fibres delivering oxygen fluxes of 11.4 ml cm−2 min−1 at 950 °C. The doping of bismuth, a highly ionic conductor, at the B-site of a barium based perovskite overcame oxygen ionic transport limitations even at temperatures as low as 600 °C.
