“…Experimental results [111, 112] further show that undoped LaMnO 3 , LaCoO 3 , and LaFeO 3 partially lost their initial activity for methane combustion after poisoning. In this study, the catalyst most sensitive to poisoning was LaFeO 3 [111, 112] . The A‐site doping of the manganites has a different effect on the catalytic activity and also on the resistance to sulfur poisoning.…”

“…[108,109] It was demonstrated that manganites with B-site doped cobalt or iron show increased catalytic activity and improved resistance to poisoning. [110] Experimental results [111,112] further show that undoped LaMnO 3 , LaCoO 3 , and LaFeO 3 partially lost their initial activity for methane combustion after poisoning. In this study, the catalyst most sensitive to poisoning was LaFeO 3 .…”

“…In this study, the catalyst most sensitive to poisoning was LaFeO 3 . [111,112] The A-site doping of the manganites has a different effect on the catalytic activity and also on the resistance to sulfur poisoning. The study confirms that La 0.8 Sr 0.2 MnO 3 has a significant resistance to sulfur poisoning compared to the rest of the analyzed compositions.…”

Noble-metal-free catalytic nanoparticles hold the promise being abundant, low-cost materials having a small environmental footprint and excellent performance, albeit inferior to that of noble metal counterparts. Several materials have a long-standing history of success in photocatalysis, in particular titanium dioxide, and in recent years more complex oxides and added functionality have emerged with enhanced performance. We will discuss different approaches related to the use of non-centrosymmetric and polar oxide nanoparticles and how the bulk photovoltaic effect, piezoelectricity, and pyroelectricity add to photocatalysis and tribocatalysis. We pay special attention to discriminate between the role of free versus that of bound charges within the catalyst, which is crucial to disentangle the different contributions to the catalytic reaction for the benefit of the overall enhanced catalytic performance in e.g. wastewater treatment and ultimately water-splitting.

“…Minshan Meng et al [125] Rojas Cervantes and colleagues investigated the use of catalysts of perovskite oxide-based oxidation for wastewater treatment using various oxidants and so UV-visible irradiation producing photocatalysis [127]. The researchers investigate the physicochemical aspects of perovskite oxides like lattice oxygen vacancy and mobility formation as well as maintaining distinct states of oxidation of component elements which may be used to increase AOP employing radicals [128].…”

Perovskites are materials with crystal structures comparable to perovskite (mineral). The backbone of perovskite is calcium titanium oxide (CaTiO3). Perovskite oxides with the general formula ABOx are highly important. In the general formula of perovskite ABX3, A & B are cations, where X is an anion that binds with two cations. Perovskites have proven their versatility in catalysis, photovoltaics, solar cells, electrode conducting material, etc. Due to their unique structural properties and applications, they are compatible with elements having metallic approximately 90% of the periodic table.This review discusses the synthesis and catalytic application of perovskite oxides. There are five sections to this review: (a) a brief description of perovskite oxides, (b) the synthesis of perovskite oxides with various properties, (c) general characterization, (d) catalytic applications, and (e) conclusions and future perspectives.
