CO oxidation and methane combustion on LaAl1−xFexO3 perovskite solid solutions

Effect of the synthesis conditions on the redox and catalytic properties in oxidation reactions of LaCo1−xFexO3

“…An additional signal for LaFeO 3 is observed. The reduction of iron is performed in one step and is very limited, as shown by Ciambelli et al [38,39]. This reduction of Fe 4+ to Fe 3+ occurs at low temperature which could explain the large reduction observed for this sample (more than 1 e À at the inflexion point in Fig.…”

Low-temperature NH3-SCR of NO by lanthanum manganite perovskites: Effect of A-/B-site substitution and TiO2/CeO2 support

“…As the calcination temperature dropped to 500 [31,32] that perovskite preparation through a traditionally ceramic method usually involves a temperature as high as 800 • C to ensure the formation of the crystalline phase. A-or B-site partial substitutions did not introduce any other impurity phases, indicating that these metallic cations readily incorporate into the LaMnO 3 lattice (Fig.…”

Preparation of Highly Active and Stable Perovskite-like Catalyst by Combustion Method: Effect of Complex

“…The catalytic performances of LaSrNiO 4 prepared under different conditions are tested by CO oxidation reaction, since this reaction not only has an interest to eliminate CO-a poisonous compound from exhaust, but also is a test reaction for surface structureactivity correlation studies [22]. Results indicate that sample prepared with oxalic acid as the complex shows far higher activity than that prepared by citric acid, suggesting that oxalic acid would be a more preferential complex in the preparation of highly active perovskite-type catalyst by combustion method.…”
