“…Popov et al [133] reported that substitution of Co by W to a BSCF not only improves the CO 2 tolerance, but the O 2 permeability was also enhanced one order of magnitude. The same effect has been reported by Shubnikoba et al Cobalt was substituted with molybdenum [64].…”

Mixed ionic-electronic conducting membranes have seen significant progress over the last 25 years as efficient ways to obtain oxygen separation from air and for their integration in chemical production systems where pure oxygen in small amounts is needed. Perovskite materials are the most employed materials for membrane preparation. However, they have poor phase stability and are prone to poisoning when subjected to CO2 and SO2, which limits their industrial application. To solve this, the so-called dual-phase membranes are attracting greater attention. In this review, recent advances on self-supported and supported oxygen membranes and factors that affect the oxygen permeation and membrane stability are presented. Possible ways for further improvements that can be pursued to increase the oxygen permeation rate are also indicated. Lastly, an overview of the most relevant examples of membrane reactors in which oxygen membranes have been integrated are provided.

“…Thus, numerous works in the literature suggest the improvement of the chemical stability of BSCF perovskite at high temperature by substituting Co with a judicious cation in the B site: [9]. Curiously, only few studies reported the oxygen semi-permeation properties of Ba 0.5 Sr 0.5 FeO 3-δ material (denoted BSF55 in this work) or Ba 1-x Sr x FeO 3-δ materials (denoted BSF in this work).…”

This work is focused on the evaluation of oxygen semi-permeation performances of free cobalt perovskite membrane materials, Ba 1-x Sr x FeO 3-δ perovskites. A wide range of Ba and Sr contents were studied. The best performances were obtained for Ba 0.9 Sr 0.1 FeO 3-δ perovskite membranes with oxygen fluxes of 4.1 10 -3 mol.m -2 .s -1 at 850°C. For a better understanding of the rate determining step of oxygen transport through Ba 1-x Sr x FeO 3-δ perovskite membranes, the oxygen diffusion and oxygen desorption coefficients were determined for Ba 1-x Sr x FeO 3-δ perovskite membranes (with x = 0.1, 0.5, and 0.7) by a specific method based on oxygen semi-permeation.
