“…For the modification of membrane configuration, in addition to preparing asymmetric and symmetric OPMs, researchers have proposed the preparation of different membrane shapes to improve the performance of OPMs. The configurations of OPMs include disk membrane, tubular membrane, fiber membrane, and capillary membrane. − As shown in Figure , compared to the other three types of membranes, disk membranes have significant differences in shape. Tubular membranes, hollow fiber membranes, and capillary membranes have similar shapes, but the tubular membranes have the largest diameters.…”

A ceramic oxygen-permeable membrane (OPM) with theoretical 100% selective oxygen permeation is attracting intensive attention in carbon capture technology, membrane reactors, industrial oxygen production, solid oxide fuel cells, and so on. Currently, much effort has been focused on exploring mixed ionic and electronic conducting (MIEC) perovskite oxides OPMs, such as Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3-δ and La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-δ . Considering the unsatisfactory oxygen permeability and stability of such perovskite-based OPMs for actual requirements, there is an urgent need to develop more active and stable OPMs, as well as modification strategies to enhance the performance of such OPMs. Herein, we provide an intime review of modification strategies toward MIEC OPMs, including membrane surface modification, membrane composition modification, and membrane configuration design. Followed on this, we highlight and summarize the working principle of OPMs and related membrane modification methods. Finally, the prospects and challenges of OPMs in this dynamic research area are assessed, shining some light on the effective modification of OPMs toward various applications.
