| description | © 2018 Institution of Chemical Engineers Oxygen-selective perovskite hollow fiber membrane can be used to obtain an effective oxygen separation from air at high temperature (above 700 °C) for large scale application. Here, we display that oxygen permeation fluxes of La 0.6 Sr 0.4 CoO 3 (LSC 113 ) hollow fiber membrane was enhanced by macrostructure modification and (La,Sr) 2 CoO 4 (LSC 214 ) surface decoration. By changing the cross-section macrostructure from sandwich structure (for LSC-a fiber) to asymmetric structure (for LSC-b fiber), the oxygen flux was improved by up to 3.6-fold. Applying porous LSC 214 decoration on LSC 113 furthermore enhanced the oxygen fluxes for LSC-a and LSC-b, by up to 6.8-fold and 1.9-fold, respectively. |
