Effect of humidified atmosphere on the physicochemical properties of S-doped La2Mo2O9 oxide-ion conductors

Phosphorus-substitution effect on the phase stabilization, electrical and spectroscopic properties of LAMOX-based electrolyte for solid oxide fuel cells

“…). Additionally, the internal vibrational modes of a tetrahedral MoO 4 group of the specific original compound with y = 0 are explicated with details in literature 18 . Moreover, to supplement the XRD data, IR absorption was investigated.…”

“…This is due to several factors including the starting materials, the substituted element, and the type of atmospheric conditions used during the synthesis process. 18 It is crucial to better understand how a substitution impacts the local patterns and the resulting material properties. LAMOX with molybdenum substituted by phosphorus is an example of a cationic substitution system in which saturation occurs at low concentrations as proved by Pahari et al , since 2012.…”

Boosted Sacrificial‐Agent‐Free Selective Photoreduction of CO2 to CH3OH by Rhenium Atomically Dispersed on Indium Oxide

“…All Raman peaks on pure In 2 O 3 and 2Re-In 2 O 3 are induced by In 2 O 3 . [14,27] Raman peaks at 308 (I 1 ) and 365 (I 2 ) cm À 1 are related to O def , and a larger intensity ratio of I 2 / I 1 indicates more O def present on material. [14,27,28] I 2 /I 1 ratios on pure In 2 O 3 and 2Re-In 2 O 3 are 0.11 and 0.95 respectively.…”

“…[14,27] Raman peaks at 308 (I 1 ) and 365 (I 2 ) cm À 1 are related to O def , and a larger intensity ratio of I 2 / I 1 indicates more O def present on material. [14,27,28] I 2 /I 1 ratios on pure In 2 O 3 and 2Re-In 2 O 3 are 0.11 and 0.95 respectively. Thus, 2Re-In 2 O 3 has more O def than pure In 2 O 3 .…”

“…[11,12] This is also shown by Rietveld refinement XRD patterns (Figure 1, Table S2). [13,14] X-ray photoelectron spectroscopy (XPS) curves demonstrate presence of In, O and Re on Re-containing photocatalysts (Figure S5). Re 4 f XPS spectrum of 2Re-In 2 O 3 2a).…”
