Cold sintering of perovskite‐based mixed conducting membrane for oxygen separation

“…Oxygen permeation experiments of SCF membranes were performed in a vertical high‐temperature gas permeation system reported previously 41 . The feed side was exposed in static air with a flow rate of helium at the sweep side of 70 mL min −1 .…”

“…Oxygen permeation experiments of SCF membranes were performed in a vertical high-temperature gas permeation system reported previously. 41 The feed side was exposed in static air with a flow rate of helium at the sweep side of 70 mL min À1 . The temperature of the membrane samples was monitored via a furnace (KSL-1200X, Hefei Kejing Materials Technology Co., Ltd., China).…”

The effect of fluid dynamics conditions and combustion reactions on the performance and heat and mass transfer distribution of dual-phase oxygen transport membranes

“…Specially, the oxygen permeation process is based on the local conditions near the membrane surface [15]. Therefore, it is very important to understand the internal flow field, oxygen concentration and temperature distribution during its working process to further analyze the oxygen permeation mechanism and improve the oxygen permeability [3,16]. The commonly used experimental methods are not only expensive and timeconsuming, but also difficult to operate the specific distribution of important parameters in real-time intuitive feedback process [17].…”

Water interaction with B-site (B = Al, Zr, Nb, and W) doped SrFeO3−δ-based perovskite surfaces for thermochemical water splitting applications

“…[8][9][10][11] Among them, the use of oxygen transport membrane technology for hydrogen production by water splitting has been intensively studied by researchers in recent years. [12][13][14] It is based on the concept of continuously splitting water to produce hydrogen through a mixed ionic-electronic conductor (MIEC) oxygen transport membrane (OTM). The selection of an appropriate oxygen exchange material (OEM) is the key to the application of TWS, and an OTM reactor based on an OEM has the advantage of integrated reaction and separation, thereby simplifying the chemical processes by coupling the oxygen-supply, oxygen-separation, and oxygen-consumption reactions into a single unit.…”
