Structural transformations in cubic structure of Mn/Co perovskites in reducing and oxidizing atmospheres

Structural Reversibility and Nickel Particle stability in Lanthanum Iron Nickel Perovskite‐Type Catalysts

“…The maximum H 2 consumption of the high‐temperature event shifted with increasing Ni content from above 800 °C for LFO to 475 °C for LaNiO 3± δ (Figure S5). In agreement with previous reports, this high‐temperature event was attributed to the structural changes that occurred during reduction as a result of the collapse of the perovskite lattice into metallic B‐site elements and La 2 O 3 …”

Photocatalytic degradation of C.I. Direct Red 23 in aqueous solutions under UV irradiation using SrTiO3/CeO2 composite as the catalyst

“…In these compounds, the alkaline earth metals behave only as the balance ions in the A site and the titanate framework plays the main role in the structure and properties with Ti in the B sites. The activity of perovskite is improved by partial replacement of the B-site metal with ions of different valency, such as Ce [13]. To the best of our knowledge, the confirmation and optimization of the efficiency of the perovskite catalyst and the degradation pathway for the photodegradation of azo dyes have received little attention in the literature.…”

Methane conversion and SO2 resistance of LaMn1−xFexO3 (x=0.4, 0.5, 0.6, 1) perovskite catalysts promoted with palladium

“…The method has been described previously [10,11]. Stoichiometric amounts of commercially available nitrates were dissolved in water.…”

“…The A-site cations are usually rare earth or earth metals and the B-site cations are first row transition metals. Ability to alter the catalytic properties of perovskites by partial substitution of the A-and B-sites metals [7][8][9][10][11] makes them of considerable interest for exhaust * Corresponding author.
