“…A high fraction of Fe 4+ is observed in LaFe 1-x Mg x O 3 perovskite and it increases with the addition of Mg content leading to lower catalytic activity at low temperatures [77]. Taguchi et al [248] reported that Ca(Mn 0. The significantly lower T 50 value of the Ca(Mn 0.6 Ti 0.4 )O 3 system was attributed to the increased content of Mn 3+ cations which act as oxygen adsorption sites [78,248,249].…”

This review paper focuses on perovskite-type materials as (photo)catalysts for energy and environmental applications. After a short introduction and the description of the structure of inorganic and hybrid organic-inorganic perovskites, the methods of preparation of inorganic perovskites both as powders via chemical routes and as thin films via laser-based techniques are tackled with, for the first, an analysis of the influence of the preparation method on the specific surface area of the material obtained. Then, the (photo)catalytic applications of the perovskites in energy production either in the form of hydrogen via water photodecomposition or by methane combustion, and in the removal of organic pollutants from waste waters, are reviewed.

“…[3], which offer the possibility of studying the relationship between structure properties and catalytic performances [4], and hence comprehending the reaction nature. As a result, these oxides are widely applied in catalysis as catalyst of, such as, CO oxidation [5,6], NO reduction [7,8], CH 4 combustion [9][10][11], etc.…”

Perovskite-like oxides (i.e., LaSrNiO 4 ) prepared by combustion method with various complexes and amounts are compared and their catalytic performances for CO oxidation are tested. Results indicate that sample prepared with oxalic acid as the complex and 100% in excess of cations shows the best and stable activity for oxidation reaction, suggesting that oxalic acid is a preferential complex in the synthesis of perovskite-like catalyst by combustion method.

“…This is due to the higher enthalpy of formation of CaTiO 3 compared to CaMnO 3 [27], which stabilizes the perovskite structure at reducing conditions of the fuel reactor. CaMn 1-x Ti x O 3-d has proven to have high activity with respect to CH 4 reduction [28], and introduction of only 12.5% titanium on the B-site improves the spontaneous oxygen release kinetics [29]. Furthermore, it has been shown that it has good chemical stability and shows small dimensional changes upon redox cycling [30].…”

The CLOU performance of the CaTi x Mn 0.9-x Mg 0.1 O 3 (CMTM) perovskite-type system was investigated, comparing materials produced at laboratory scale with those made at industrial ton scale. The CLOU and conversion performances were studied by a micropacked bed reactor, and crystalline phase structure and homogeneity and bulk density identified as the most important parameters affecting the performance of the OCM. Bulk density is correlated with the sintering temperature, atmosphere and time at sintering temperature, while phase homogeneity is a function of the raw materials chosen, agglomeration method and sintering procedure. Specific challenges are identified in the control of slurry homogeneity and sintering conditions in upscaled production. The degree of sintering affects the chemo-mechanical properties of the material (crushing strength and attrition index), physical properties (specific surface area), and more importantly the crystalline phases formed and their homogeneity: the quantity of ''active'' crystalline phases present directly determines the thermochemical conversion properties (i.e., CLOU capacity and methane conversion), oxygen transfer capacity and kinetics.
