The thermal decomposition of silver (I, III) oxide: A combined XRD, FT-IR and Raman spectroscopic study
TL;DR: In this article, the vibrational spectra for polycrystalline powders of AgO and Ag2O are discussed in relation to its crystal structure, and were found to be consistent with factor group analysis predictions.
Journal ArticleDOI
Insights into the function of silver as an oxidation catalyst by ab initio atomistic thermodynamics
TL;DR: In this article, the phase diagram of O/Ag(111) is obtained from density-functional theory and taking into account the temperature and pressure via the oxygen chemical potential, and the results reveal that a thin surface-oxide structure is most stable for the temperature/pressure range of ethylene epoxidation and that it contains the species actuating the catalysis.

TL;DR: In this article, the active phase of Pd NPs is exploited to select reaction pathways for CO2 electroreduction, and the main product can be selectively produced with high Faradaic efficiencies and mass activities in the potential window of 0.05 to −0.9 V with scalable application demonstration.
Journal ArticleDOI
Effect of subsurface oxygen on the reactivity of the Ag(111) surface.
TL;DR: These findings point to the important role that near-surface impurities, such as O(sb), can play in determining the thermochemistry and kinetics of elementary steps catalyzed by transition metal surfaces.

In Situ Raman Spectroscopy of Anodic Films Formed on Copper and Silver in Sodium Hydroxide Solution
TL;DR: In situ Raman spectroscopy and cyclic voltammetry have been used simultaneously to study anodic film growth and dissolution on Cu and Ag in strongly alkaline solution as mentioned in this paper.

Oxygen-induced restructuring of Ag(111)
Xinhe Bao,Johannes V. Barth,G. Lehmpfuhl,Rolf Schuster,Y. Uchida,Robert Schlögl,Gerhard Ertl +6 more
TL;DR: In this paper, the incorporation of oxygen atoms in subsurface sites causes a slight expansion of the topmost layer by about 3% which accounts for the formation of the observed moire pattern.
Journal ArticleDOI
Ag electrode reaction in NaOH solution studied by in-situ Raman spectroscopy
TL;DR: In this paper, the Raman spectrum is measured while the electrode potential is swept and two lines are observed at 470 and 860 cm −1 in a wider electrode potential range.
Journal ArticleDOI
In‐situ Raman Studies of Ethylene Oxidation at Ag(111) and Ag(110) under Catalytic Reaction Conditions
TL;DR: In this paper, the first Raman investigations at single crystalline Ag(111), Ag(110) and micro-faceted Ag (110) samples, which were exposed to N2 or N2 + reactive gases (oxygen and ethylene), were presented.
