This paper presents the study of ethanol electrooxidation on Pt(111) electrode modified by different coverage degrees of a submonolayer of osmium nanoislands, which were obtained by spontaneous deposition. The ethanol oxidation reaction was extensively studied by employing in situ FTIR. Collections of spectra of the ethanol adsorption and oxidation processes were acquired over a series of positive...
In the present work, the morphology and composition of osmium deposits formed in submonolayer amount on Pt(100) and Pt(111) single crystal surfaces either by spontaneous deposition or by electrolysis at 50mV in different deposition times (t dep ), were studied. The cyclic voltammetric curves for Pt(100)/Os and Pt(111)/Os were recorded in the potential range where the oxidation of...
