Reactivity and Morphology of Oxygen-Modified Au Surfaces
(American Chemical Society, 2012-08-07)
Inducing the adsorption of oxygen on gold surfaces transforms the inert metal into a surprisingly reactive material, which acts as a highly selective, low-temperature catalyst. The strong interaction of atomic oxygen with ...
Local atomic structure in tetragonal pure ZrO2 nanopowders
(Wiley Blackwell Publishing, Inc, 2010-04)
The local atomic structures around the Zr atom of pure (undoped) ZrO 2 nanopowders with different average crystallite sizes, ranging from 7 to 40 nm, have been investigated. The nanopowders were synthesized by different ...
Binding of Oxygen on Single-Atom Sites on Au/Pd(100) Alloys with High Gold Coverages
(American Chemical Society, 2021-05-03)
Oxygen adsorption was studied on a Au/Pd(100) single crystal as a model for single-atom-alloy catalysts since the surface contains isolated palladium atoms surrounded by gold at high gold coverages, and density functional ...
Dual oxygen defects in layered La1.2Sr0.8-xBaxInO4+δ (x = 0.2, 0.3) oxide-Ion conductors: A neutron diffraction study
(Molecular Diversity Preservation International, 2019-05)
The title compounds exhibit a K2NiF4-type layered perovskite structure; they are based on the La1.2Sr0.8InO4+δ oxide, which was found to exhibit excellent features as fast oxide-ion conductor via an interstitial oxygen ...
Experimental and theoretical study of the reactions of O(3P) with 3-chloropropene and 2-chloropropene between 298 and 359 K
(Elsevier Science, 2009-11)
The temperature dependences of the rate coefficients of the gas-phase reactions of O(3P) atoms with CH2{double bond, long}CHCH2Cl and CH2{double bond, long}CClCH3 were studied in the range 298-359 K, using the discharge ...
Tungsten oxide nanowire on copper surfaces: A DFT model
(Royal Society of Chemistry, 2016-09)
We studied a model of a one dimensional tungsten oxide nanowire on a reconstructed Cu(110) surface by density functional theory calculations. The effect of oxygen vacancies on the electronic structure was analyzed (DOS). ...
Initial steps of oxidative etching of MoS 2 basal planeinduced by O 2
(American Chemical Society, 2020-06)
We have investigated the first stages of oxidation of the basal plane of MoS2 with O2. The different intermediates in the energy landscape were found at 0 K with nudged-elastic band calculations, and their reactivity was ...
Adsorption and Decomposition of Glycerol on Pristine and Oxygen Modified Au(111) Surfaces
(Springer/Plenum Publishers, 2019-08)
Research on biomass derived raw materials for conventional catalytic processes, especially those directed to replace human dependence on fossil-based energy, is a high priority academic topic worldwide. Glycerol, the ...
Water insertion and combined interstitial-vacancy oxygen conduction in the layered perovskites La1.2Sr0.8−xBaxInO4+δ
(Royal Society of Chemistry, 2019-05)
Layered perovskites of K2NiF4-type consist of single octahedral sheets alternating with NaCl-type layers, containing a substantial interstitial space. Based on the parent LaSrInO4+δ oxide, the series of title compounds ...
Sensitized photooxidation of thyroidal hormones. Evidence for heavy atom effect on singlet molecular oxygen [O2(1Δ g)]-mediated photoreactions
(Wiley Blackwell Publishing, Inc, 2005-03)
Thyronine derivatives are essential indicators of thyroid gland diseases in clinical diagnosis and are currently used as standards for developing ordinary biochemical assays. Photo-oxidation of gland hormones of the thyronine ...
