Comparative study of CO adsorption on planar and tetrahedral Pt nanoclusters supported on TiO2(110) stoichiometric and reduced surfaces
(Elsevier Science, 2017-04-01)
TiO2 is a widely used material due to its electronic and catalytic properties, which are of interest for technological applications. In catalysis it is generally used as support for different catalyzers, such as for example ...

Formation of SO4H2 on the Pt{110}(1×2) surface. A DFT study
(Elsevier Science, 2021-05)
Density functional theory is used to calculate energy differences for two surface reactions on the Pt{110}(1×2) surface: SO2 ↔ SO + O and SO3 ↔ SO2 + O, first. Formation of SO3 is preferred energetically. Second, several ...
Ethanol electro-oxidation over Pt(h k l): Comparative study on the reaction intermediates probed by FTIR and SFG spectroscopies
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
We have investigated the adsorbed intermediates of ethanol electro-oxidation at Pt(1 1 1), Pt(1 0 0) and Pt(1 1 0) using FTIR and SFG spectroscopies. Mainly, we focus on the CO formation. The aim of the present work is to ...
Voltammetric characterization of stepped platinum single crystal surfaces vicinal to the (110) pole
(ELSEVIER SCIENCE INC, 2009)
Platinum stepped surfaces vicinal to the (1 1 0) crystallographic pole have been investigated voltammetrically in 0.1 M HClO(4) and 0.1 M H(2)SO(4) solutions. Changes in the voltammetric profile with the step density suggest ...

Oxygen assisted H2O dissociation on the Pt{110}(1 × 2) surface from first principles
(Elsevier Science, 2014-04)
Water dissociation with and without oxygen coadsorption is investigated on the Pt{110}(1 × 2) surface at low coverage from first principles. Calculations indicate that desorption of the water molecule is likely to occur ...
