“…However, the development of the 4-end membrane operation mode technology is hampered since the state-of-the-art OTMs suffer from low chemical stability toward corrosive components of the flue gas such as CO 2 and SO 2 , which lead to a poor oxygen permeation performance and even membrane destruction [9][10][11][12][13][14]. It is known that single phase perovskite-type OTM materials (ABO 3 ) with a high content of alkaline-earth metals on the A site, easily react with CO 2 and SO 2 forming carbonates and sulfates [15][16][17][18].…”

“…The solvent of the slurry is typically water [39,117,[120][121][122][123][124] but organic solvents, such as n-butanol, are sometimes employed [62,63]. Similarly to extrusion pastes, various additives can be used to tune the rheological properties of the slurry and improve the quality of the coating.…”

“…The partial substitution of the B-site cation by a noble metal dramatically increases the sulfur tolerance of perovskite-type oxides [61]. Tzimpilis [62,63]. Regardless of their promising performance, noble metal-free perovskite type oxides still remain less active than noble metal supported catalysts [64].…”

Structured Perovskite-Based Catalysts and Their Application as Three-Way Catalytic Converters—A Review

Automotive Three-Way Catalysts (TWC) were introduced more than 40 years ago. Despite that, the development of a sustainable TWC still remains a critical research topic owing to the increasingly stringent emission regulations together with the price and scarcity of precious metals. Among other material classes, perovskite-type oxides are known to be valuable alternatives to conventionally used TWC compositions and have demonstrated to be suitable for a wide range of automotive applications, ranging from TWC to Diesel Oxidation Catalysts (DOC), from NO x Storage Reduction catalysts (NSR) to soot combustion catalysts. The interest in these catalysts has been revitalized in the past ten years by the introduction of the concept of catalyst regenerability of perovskite-based TWC, which is in principle well applicable to other catalytic processes as well, and by the possibility to reduce the amounts of critical elements, such as precious metals without seriously lowering the catalytic performance. The aim of this review is to show that perovskite-type oxides have the potential to fulfil the requirements (high activity, stability, and possibility to be included into structured catalysts) for implementation in TWC.

“…Note that the activity of the catalysts was evaluated in mixed gases without water and particulate matter, both of which would poison the catalysts in real gasoline exhaust [34]. In addition, the high temperatures in practice would also degrade the activity of the catalysts [35]. Therefore, in future work, we will focus on promoting the performance of LSCM oxides for three-way catalysis and investigating their stability in a simulated model gas similar to the real gasoline exhaust.…”

Mn-doped La 0.8 Sr 0.2 CoO 3 perovskite oxides (La 0.8 Sr 0.2 Co 1-x Mn x O 3 ; x = 0, 0.1, 0.3, 0.5) were synthesized by a modified sol-gel method. The phase-pure oxides were obtained. CoO and carbonates were formed on the surface of La 0.8 Sr 0.2 CoO 3 . With increasing doping content, these impurities were reduced while the stability of the perovskite structure was improved. The valence state of B-site ions and the amount of absorbed oxygen were influenced by Mn doping. The catalytic activity of the perovskite catalysts was investigated for CO oxidation and simultaneous removal of CO, C 3 H 8 , and NO. For CO and NO removal, La 0.8 Sr 0.2 Co 0.9 Mn 0.1 O 3 exhibited the best performance. For C 3 H 8 removal, the reactivity was promoted linearly with the doping content. The structure-activity relationship is also discussed.
