Oxygen reduction reaction on spontaneously and potentiodynamically formed Au/TiO2 composite surfaces
(Elsevier, 2007)
From aqueous solutions, gold was deposited on freshly polished titanium surface either by displacement reaction or by potentiodynamic polarization. Both of these procedures resulted in the formation of Au/TiO2 composite ...
The origin of high activity of Pt-Au surfaces in the formic acid oxidation
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
We have investigated the oxidation of HCOOH on Au-modified Pt (Au"Pt) and Pt-modified Au (Pt"Au) electrodes to establish the role of the ensemble and the electronic effect in the catalysis of this reaction. The surfaces ...
In situ STM imaging of spontaneously deposited ruthenium on Au(111)
(Elsevier, 2002)
Spontaneous deposition of ruthenium on Au(1 1 1) surfaces from 1.0 mM RuCl3 + 0.5 M H2SO4 (or 0.1 M HClO4) solutions was investigated by in situ STM and cyclic voltammetry, focusing on the morphology of the resulting ...
In situ STM study of nanosized Ru and Os islands spontaneously deposited on Pt(111) and Au(111) electrodes
(Elsevier, 2004)
We provide an overview of structure and reactivity of selected bimetallic single crystal electrodes obtained by the method of spontaneous deposition. The surfaces that are described and compared are the following: Au(111)/Ru, ...
