Crystalline LaCoO3 perovskite as a novel catalyst for glycerol transesterification

Advanced High Entropy Perovskite Oxide Electrocatalyst for Oxygen Evolution Reaction

“…The reason might be the existence of multi‐transition metals in different oxidation states, causing the Jahn–Teller distortion along with polarization of MO bonds arising due to local distortion of crystalline structure with lower symmetry. [ 34,35 ] The morphologies of perovskite oxides are shown in Figure 1c–h. All the HEPOs consist of nanoparticles (NPs) having uniform diameters less than 100 nm, except that apparent particle agglomeration is seen in L5M2Cr.…”

Catalytic steam reforming of simulated bio-oil for green hydrogen production using highly active LaNixCo1−xO3 perovskite catalysts

“…2(a)) exhibit peaks at 2 θ values of 23.2°, 32.8°, 33.2°, 40.5°, 41.2°, 47.4°, 58.5°, 58.8°, 59.83°, 68.7°, 69.7°, 78.5° and 79.1° attributed to the (012), (110), (104), (202), (006), (024), (030), (214), (018), (220), (208), (134) and (128) lattices of the perovskite structure. 31,36–39 The presence of all these characteristic peaks of the perovskite in the diffractograms indicates the successful formation of a perovskite crystalline phase in all synthesized catalyst samples. Furthermore, as expected, no shifting of the peaks was observed when the loading amounts of Ni and Co were changed in any of the samples because of the fact that Ni and Co have nearly similar ionic radii.…”

“…After complete reduction, Ni and Co metal species form a very strong interaction with metals and oxides, especially in perovskite and spinel catalysts. 36–38,48…”

Recent Advances in Glycerol Catalytic Valorization: A Review

“…A larger amount of template eventually led to a detriment in the catalytic activity. Some authors have employed crystalline perovskite to obtain glycidol via the decarboxylation of glycerol carbonate in one pot [219]. For the synthesis of GC, they have used glycerol and di-methylcarbonate.…”
