TL;DR: In this article, the initial oxidation of Pt surfaces is investigated and it is shown that these oxidize in successive stages depending on site geometry as well as the adsorption behavior of the electrolyte anion.

TL;DR: In this article, the thermodynamics of the so-called perfectly polarizable electrode were employed to analyze the voltammograms of a Pt(1 1 1) electrode in KBr solutions with an excess of a supporting electrolyte.

TL;DR: In this article, the electrocatalytic activity of different shape-controlled gold nanoparticles and nanorods has been studied by scanning electrochemical microscopy (SECM), where TEM images and lead underpotential deposition (UPD) voltammetric profiles were used to physically and electrochemically characterize all gold particles studied here.

TL;DR: In this paper, the authors acknowledge the financial support of NSERC through an Alexander Graham Bell Canada Graduate Scholarship (CGS) (Master degree) and the Michael Smith Foreign Study Supplements program, as well as the Fond Quebecois de la Recherche sur la Nature et les Technologies (FQRNT) through the master research scholarships (B1) program.

TL;DR: In this article, the effects of anion adsorption and surface structure on the measured current and oxidation mechanism were investigated using cyclic voltammetry and FTIR techniques, and it was shown that the main product of ethanol oxidation on preferentially oriented Pt nanoparticles is acetic acid, and the amount of CO2 produced can be considered negligible.
