“…Due to the presence of mixed electron‐ion conductivity, perovskites have been widely used as O 2 , [ 199 ] H 2 , [ 200 ] CO, [ 201 ] CO 2 , [ 202 ] N 2 , NH 3 , [ 203 ] and H 2 S [ 204 ] sensors and O 2 , [ 205 ] H 2 , [ 206 ] and CO 2 [ 207 ] separation membranes. However, the low corrosion resistance and poor stability of conventional perovskites severely limit the large‐scale commercialization of perovskite‐based devices.…”

Perovskites have shown tremendous promise as functional materials for several energy conversion and storage technologies, including rechargeable batteries, (electro)catalysts, fuel cells, and solar cells. Due to their excellent operational stability and performance, high-entropy perovskites (HEPs) have emerged as a new type of perovskite framework. Herein, this work reviews the recent progress in the development of HEPs, including synthesis methods and applications. Effective strategies for the design of HEPs through atomistic computations are also surveyed. Finally, an outlook of this field provides guidance for the development of new and improved HEPs.

“…Furthermore, they are used as supercapacitors for electrochemical energy storage (batteries and electrochemical capacitors) [7][8][9]. Some have successfully been used as perovskite solar cells (PVSCs) [10][11][12][13] due to their remarkable efficiency increase of nearly 24% compared to commercial Si solar cells [1], or ceramic foam membranes for oxygen [2] or carbon dioxide transport [14]. Others have been used as superior perovskite electrocatalysts [15], possessing multiferroic properties together with polarization-induced photoelectrochemical activity, for water splitting applications [16]; and as so-called oxygen carriers in energy-generation processes [17][18][19] due to the reversible and fast change of oxygen content for many cycles at high temperatures.…”

Oxide Strontium-Barium Perovskites Ceramics: Examinations of Structural Phase Transitions and Potential Application as Oxygen Carriers

2023

The structural properties of selected (Ba1−xSrx)PbO3 ceramics were examined at 14–1148 K using X-ray powder diffraction (XRD). These materials are attractive due to their variety of applications, such as, for example, high-temperature thermoelectric energy conversion. Attention was paid to this paper as a continuation of the previous examinations of higher Sr2+ concentrations. The type of perovskite distortion and temperatures of the structural phase transitions (SPTs) were determined from the splitting of certain pseudocubic lines. At this point, for example (Ba0.3Sr0.7)PbO3 showed three temperature-induced SPTs. When the amount of Sr increased in the samples, no phase transition was observed, which is contrary to the data previously demonstrated in the literature. The quality of the ceramics was examined by scanning electron microscopy-energy dispersion X-ray spectroscopy (SEM-EDS), demonstrating their homogeneity and uniform elements dispersion. As a result of profound crystal investigations, confirmed by thermogravimetric analysis and quadrupole mass spectroscopy (TGA-QMS), a phase diagram was prepared for the (Ba1−xSrx)PbO3 system based on our former and recent study. Also, the investigation of a new application for the (Ba1−xSrx)PbO3 family is presented in this paper for the first time. The TGA analysis was conducted on Illinois#6 hard coal to evaluate the capability of perovskites to be used in the chemical looping combustion (CLC) process in a range of temperatures 1073–1173 K. Due to its thermal stability and reactivity, Ba0.9Sr0.1PbO3 is the material with the greatest potential to be applied as an oxygen carrier. The combination of strontium and barium offers encouraging results compared to the pure barium and strontium lead oxide perovskites.

“…Therefore, perovskite materials are strong candidates for developing ceramic-carbonate membranes for the selective separation of CO 2 at elevated temperatures. [21][22][23][24] For example, the ceramic oxide La 0.6 Sr 0.4 Co 0.8 Fe 0.2 O 3-δ (LSCF) is one of the materials taken as a reference. Previously obtained results indicate that in a perovskite-type material, such as LSCF, the CO 2 separation follows the reaction mechanism (Equation 1).…”

“…Perovskite‐type materials exhibit high oxygen‐ion diffusion rates through their crystalline structure and significant surface exchange kinetics under oxidizing conditions. Therefore, perovskite materials are strong candidates for developing ceramic‐carbonate membranes for the selective separation of CO 2 at elevated temperatures 21‐24 .

In this paper, it is reported the fabrication of a new dense ceramic-molten carbonate membrane used for the selective separation of carbon dioxide (CO 2 ) and oxygen (O 2 ) at elevated temperatures (850-950°C). First, it was chemically synthesized a fluorite/perovskite ceramic oxide with mixed ionic-electronic conduction properties and general formula Ce 0.9 Pr 0.1 O 2-δ /Pr 0.6 Sr 0.4 Fe 0.5 Co 0.5 O 3-δ (CP-PSFC, 60:40 wt%) by the citrate-ethylene-diamine-tetra acetic acid (EDTA) route. Then, a disk-shaped porous ceramic support partially sintered was infiltrated with a ternary mixture of molten salts of Li 2 CO 3 /Na 2 CO 3 /K 2 CO 3 composition. The permeation measurements at high temperatures suggest a concurrent separation of both species CO 2 and O 2 . The system exhibits high permeance of CO 2 and O 2 by rising to maximum values of 2.17 × 10 −7 and 0.69 × 10 −7 mol m −2 s −1 Pa −1 , respectively at 950°C. Moreover, the possibility of modulating the permeate CO 2 :O 2 ratio is envisaged by changing the fluorite to perovskite proportion in the membrane composition. The stability performance of the obtained membrane was studied under a long-term permeation test. It exhibits a remarkable thermal and chemical stability during 110 h at 875°C. This way, it corroborated the proposed new ceramic phase's excellent properties for the fabrication of supported ceramic-molten carbonate membranes.
