Preparation of LaFe0.95Pd0.05O3 perovskites and their catalytic performances in methane combustion

Perovskites as Substitutes of Noble Metals for Heterogeneous Catalysis: Dream or Reality

“…Falcón et al observed that Sr 2 FeMoO 6−δ was the most active double perovskite in the series A 2 FeMoO 6 (A = Ca, Sr, or Ba) with 80% conversion of methane at 530 °C. Finally, some perovskites were doped with palladium, either in substitution of Fe ,, or as Pd/perovskite catalysts . It was shown that Pd doping has a stronger effect on ferrites than on other perovskites.…”

Synthesis of three-dimensionally ordered macroporous LaFeO3 with enhanced methanol gas sensing properties

“…ABO 3 perovskite-type oxides, with A = rare earth and B = transition metal ion [1], have been extensively studied for various advanced technological applications, such as catalysts [2,3], fuel cells [4], Li-O 2 batteries [5], magnetic materials [6], electrode [7], and gas sensors [8][9][10][11]. This is because that the ABO 3 perovskite structure is usually with structural defects due to fluctuations between the two stable oxidation states of iron; which causes the electrical balance by insertion in the lattice of O 2 − from environmental O 2 or the occurrence of oxygen vacancies [12], ABO 3 perovskite-type oxides always show superior properties in many applications.…”

Synthesis and Characterization of A-Site Doped Lamno3 Nano Catalysts and its Application for Soot Oxidation

“…The endothermic weight loss (B 1 ) that was seen at the temperature 0-150 o C has been attributed to the loss of surface water [14][15][16] . The second decomposition stage (B 2 ) was observed at a temperature between 150-260 o C and has been ascribed to probable loss of crystalline water [17][18][19] . The main weight loss stage (B 3 ) was observed around the temperature range of 250-400 o C and this has been assigned to the breakdown of citrate, EDTA and other organic moiety present in the catalyst 12,20,21 .…”
