Dry-reforming of methane over bimetallic Ni–M/La2O3 (M = Co, Fe): The effect of the rate of La2O2CO3 formation and phase stability on the catalytic activity and stability

Low temperature CO oxidation catalysed by flower-like Ni–Co–O: how physicochemical properties influence catalytic performance

“…The rst doublet at $853.8 and $871.5 eV and the second doublet at $855.8 and $873.2 eV are assigned to Ni 2+ and Ni 3+ , respectively. 23,31,33,37 The two intensive shake-up satellites ($861.0 and $879.6 eV) are usually observed for paramagnetic Ni 2+ , and arise from charge transfer multi-electron transitions. 38,39 In addition, the small peak at $865.0 eV is assigned to the shake-up satellite of Ni 3+ .…”

“…The Co/ CeO 2 (ref. 16 and 17) 19,20 propane oxidation, 21 reforming reactions 22,23 and as an electrode material. 24 Yu et al 19 have revealed that the synergetic effect between Ni and Co over bimetallic catalysts can reduce nickel size to enhance the metal particle dispersion and accelerate the activation of adsorbed CO, thereby improving the catalytic activity and coke resistance.…”

Iron‐Doped BaMnO3 for Hybrid Water Splitting and Syngas Generation

“…In a similar vein to solar‐thermal water splitting, the chemical‐looping reforming (CLR) process also utilizes the redox properties of metal oxides for energy conversion . In such a process, a transition‐metal‐oxide‐based oxygen carrier (also known as a redox catalyst) is used to partially oxidize (POx) methane into syngas in the first step.…”

Utilization of La₂O₃ as a Support of Ga₂O₃ Photocatalyst to Enhance Activity on CO₂ Reduction with Water

“…Preparation of Ga2O3/La2O3 photocatalyst Ga2O3/La2O3 photocatalyst samples were prepared by an impregnation method. La2O3 (Kishida Chemical) was calcined at 1273 K to remove carbonate before mixing with Ga(NO3)3·8H2O (Kishida Chemical, purity; 99.0%) [27]. The amounts of them were selected to be 6 : 4 for the mass ratio of Ga2O3 and La2O3 (referred as 40 wt% Ga2O3 hereafter).…”
