Professor John B. Goodenough started his research on perovskite‐type oxides working on random‐access memory with ceramic [La,M(II)]MnO3 in the Lincoln Laboratory, Massachusetts Institute of Technology, more than 60 years ago. Since then perovskite‐type oxides have played vital roles in the field of energy conversion and storage. In this review, a brief overview is given on the structure, defect chemistry, and transport properties of perovskite oxides, especially the mixed‐valent materials with mixed electronic and ionic conductivities. The recent advances of perovskite oxides applications in the oxygen reduction reaction, oxygen evolution reaction, electrochemical water splitting reaction, metal–air batteries, solid‐state batteries, oxygen separation membranes, and solid oxide fuel cells are highlighted. Moreover, some novel design strategies for optimizing performance, like interface engineering, defect engineering, strain modulation are discussed as well. Finally, a perspective is given on how to design high‐performance perovskite oxide based materials for energy conversion and storage applications as well as the challenges involved in this task.

“…The research field on materials for gas separation membranes is constantly expanding due to the pressing industrial request for more performing materials to employ in gas treatment, such as hydrogen recovery (H 2 /CO 2 ) [1], oxygen-enriched air production (O 2 /N 2 ) [2,3], biogas up-grading [4,5] and which makes it soluble in various common organic solvents. It has been used extensively in membrane preparation and characterization under the names PEEK-WC, PEEKWC or PEK-C [22].…”

Glassy PEEK-WC vs. Rubbery Pebax®1657 Polymers: Effect on the Gas Transport in CuNi-MOF Based Mixed Matrix Membranes

Mixed matrix membranes (MMMs) are seen as promising candidates to overcome the fundamental limit of polymeric membranes, known as the so-called Robeson upper bound, which defines the best compromise between permeability and selectivity of neat polymeric membranes. To overcome this limit, the permeability of the filler particles in the MMM must be carefully matched with that of the polymer matrix. The present work shows that it is not sufficient to match only the permeability of the polymer and the dispersed phase, but that one should consider also the individual contributions of the diffusivity and the solubility of the gas in both components. Here we compare the gas transport performance of two different MMMs, containing the metal-organic framework CuNi-MOF in the rubbery Pebax ® 1657 and in the glassy poly(ether-ether-ketone) with cardo moiety, PEEK-WC. The chemical and structural properties of MMMs were investigated by means of FT-IR spectroscopy, scanning electron microscopy and EDX analysis. The influence of MOF on the mechanical and thermal properties of both polymers was investigated by tensile tests and differential scanning calorimetry, respectively. The MOF loading in Pebax ® 1657 increased the ideal H 2 /N 2 selectivity from 6 to 8 thanks to an increased H 2 permeability. In general, the MOF had little effect on the Pebax ® 165 membranes because an increase in gas solubility was neutralized by an equivalent decrease in effective diffusivity. Instead, the addition of MOF to PEEK-WC increases the ideal CO 2 /CH 4 selectivity from 30 to~48 thanks to an increased CO 2 permeability (from 6 to 48 Barrer). The increase in CO 2 permeability and CO 2 /CH 4 selectivity is maintained under mixed gas conditions. natural gas treatment (CO 2 /CH 4 ) [6], and post-combustion carbon capture from flue gas (CO 2 /N 2 ) [7]. This increasing interest is dictated by the advantages of membrane technology compared to traditional gas separation techniques. Gas separation by means of membrane technology is an economical process; it is easily scalable and it can be used in non-drastic temperature and pressure conditions, which are more environmentally friendly. Despite numerous efforts to develop new materials for gas separation, the membrane market still needs to overcome some challenges. In fact, the highly permeable rubbery polymers present low selectivity, and the highly-selective glassy polymers are less permeable. To overcome this trade-off between permeability and selectivity, extensively reported by Robeson in 1991 and in 2008 [8,9], researchers are focusing on the design and development of hybrid membranes based on the combination of two different materials in order to get the advantages of both [10]. According to this concept, a valid strategy is the embedding of porous metal-organic frameworks (MOFs) in the polymer matrix in order to obtain mixed matrix membranes (MMMs) with enhanced gas transport properties [11][12][13][14][15][16]. MOFs are an attractive new class of microporous materials built by the combination o...

“…The development of new polymers with improved gas permeability and selectivity would enhance the efficiency of membrane gas separations of industrial interest [5]. Polymers have been developed for various purposes including hydrogen recovery during ammonia preparation (H2 from N2) [6,7], oxygen or nitrogen enrichment of air (O2 from N2) [8,9]; and natural gas sweetening or biogas upgrading (CO2 from CH4) [10][11][12]. Rising concern about global warming by greenhouse gas emissions has focused attention also on pre-combustion or post-combustion carbon capture (mainly H2 from CO2, and CO2 from N2, respectively) [13,14].…”

<a>Polymer-based membranes can be used for energy efficient gas separations. Successful exploitation of new materials requires accurate knowledge of the transport properties of all gases of interest. An open source database of such data is of significant benefit to the research community. The Membrane Society of Australasia (https://membrane-australasia.org/) hosts a database for experimentally measured and reported polymer gas permeabilities. However, the database is incomplete, limiting its potential use as a research tool. Here, missing values in the database were filled using machine learning (ML). The ML model was validated against gas permeability measurements that were not recorded in the database. Through imputing the missing data, it is possible to re-analyse historical polymers and look for potential “missed” candidates with promising gas selectivity. In addition, for systems with limited experimental data, ML using sparse features was performed, and we suggest that once the permeability of CO2 and/or O2 for a polymer has been measured, most other gas permeabilities and selectivities, including those for CO2/CH4 and CO2/N2, can be quantitatively estimated. This early insight into the gas permeability of a new system can be used at an initial stage of experimental measurements to rapidly identify polymer membranes worth further investigation.</a>
