The study of the performance of Ni-based catalysts obtained from LaNiO3 perovskite-type oxides synthesized by the combustion method for the production of hydrogen by reforming of ethanol

Porous Hollow‐Structured LaNiO3 Stabilized N,S‐Codoped Graphene as an Active Electrocatalyst for Oxygen Reduction Reaction

“…Brunauer–Emmett–Teller analysis confirmed that the surface areas of porous hollow LaNiO 3 (FE‐SEM imagery shown in Figure S3, Supporting Information) and nanohybrid are 14.3 and 42.7 m 2 g −1 , respectively. The surface area of this porous hollow LaNiO 3 material is much higher than that of solid LaNiO 3 materials reported in the previous studies . In particular, the hybridization of the porous hollow LaNiO 3 spheres with N,S‐Gr displayed an over three times larger surface area than single LaNiO 3 phase.…”

Rational design of ethanol steam reforming catalyst based on analysis of Ni/La2O3 metal–support interactions

“…† The TGA of used Ni/ SiO 2 [Fig. S5(a) †] exhibited a weight loss (D 1 ) at around 400-600 °C that was the oxidation of carbon filaments, 49 while, in contrast, the used Ni/La 2 O 3 showed distinct weight losses in various temperature ranges, i.e. 200-400 °C (D 1 ), 400-600 °C (D 2 ), 620-656 °C (D 3 ) and 656-718 °C (D 4 ) (ref.…”

Oxygen Storage Characteristics and Redox Behaviors of Lanthanum Perovskite Oxides with Transition Metals in the B-Sites

“…The first reduction peak of LaNiO 3 at 460 °C is attributed to the reduction of Ni 3+ to Ni 2+ in the perovskite structure and the formation of the La 2 Ni 2 O 4 phase. When the temperature reaches 635 °C, the metal oxide containing Ni 2+ will be reduced to Ni 0 , The first reduction peak of LaCoO 3 at 486 °C is mainly the reduction of Co 3+ to Co 2+ , and the second reduction peak at 640 °C belongs to the process of the overall reduction of Co 2+ to metal Co 0 and the reduction of chemically adsorbed oxygen caused by lattice defects . The first reduction peak of La 2 CuO 4 is mainly due to the reduction of Cu 2+ to Cu 1+ , and the second reduction peak at 553 °C is the result of the reduction of Cu 1+ to Cu 0 .…”
