The effect of the calcination temperature of LaFeO3 precursors on the properties and catalytic activity of perovskite in methane oxidation

Photocatalytic Hydrogen Energy Evolution from Sugar Beet Wastewater

“…found the La/Fe ratio as 1.12 and Cho et al. determined La/Fe ratio as 1.18, it is found as 1.13 in this study so that it could be deduced that the results are in line with the literature [25,26] . TEM analysis of LFO and GLFO was previously performed and published elsewhere [27] .…”

Graphene‐supported LaFeO 3 for photocatalytic hydrogen energy production

“…It is stated in many studies in the literature that the characteristic peaks of perovskite-type catalysts are found to be 2θ where 22.63 , 32.22 , 39.73 , 46.21 , 57.45 , 67.42 , 72.12 and 76.69 and the existence of these peaks confirm that the synthesized perovskitetype catalyst has orthorhombic structure. 32,35 Graphene has a characteristic peak near 21 and it has an amorphous shape so that it does not have sharp peaks in XRD pattern. 15 As a result of the XRD analysis for the catalyst prepared within this study, it is clearly seen in the XRD diagrams that the characteristic peaks of these catalysts are present in these 2θ values.…”

Microstructural Changes in La0.5Ca0.5Mn0.5Fe0.5O3 Solid Solutions under the Influence of Catalytic Reaction of Methane Combustion

“…In real crystals, positions A and B can be occupied by different ions, including dissimilar ones, which can lead to the formation of cation-deficient structures [10,11]. For example, materials based on La 1−x M x MeO 3 (M = Ca, Sr, Ba, Me = Mn, Fe, Co) at high temperatures have mixed ionic and electronic conductivity and can be used in high-temperature electrochemical devices such as gas sensors, oxygen permeable membranes and electrodes of solid-state fuel cells and catalysts of high-temperature oxidizing processes [12][13][14].…”
