“…The result is different than previously reported for Pt(1 1 1) electrodes by Ren et al and by Hubbard [20,22]. Those studies reported maximum coverages of $0.33 nmol cm À2 at Pt(1 1 1) electrodes using thin layer and ultrahigh vacuum experimental methodologies.…”

“…In spite those efforts, the chemical identity of Q (ads) is still a subject of controversy [23]. Hubbard [20,22] has shown, using high resolution electron energy loss spectroscopy, that upon adsorption at Pt(1 1 1) electrodes the hydrogen in the hydroxyl groups dissociates from the H 2 Q (aq) molecule. This suggests that the most likely oxidation product of Eq.…”

“…The resulting adsorbed monolayers have been investigated [20][21][22][23] using STM, LEED, AES, HREELS, FTIR and electrochemistry. In spite those efforts, the chemical identity of Q (ads) is still a subject of controversy [23].…”

“…In fundamental studies, well-ordered Pt(h k l) single crystal electrodes have received most of the attention; having been one of the most commonly used materials for the construction of solid electrodes. Like CO, that served as a model chemisorbate in the study of gas-solid heterogeneous interfaces, H 2 Q and related quinonoid moieties have served as prototypical organic chemisorbates in what is now an increasing body of work at solid-liquid electrode interfaces [20][21][22][23][24]. From an analytical standpoint, their richness in reactivity makes them promising probes of chemical reactivity at electrode solution interfaces.…”

“…Thus, our complex signal at 1650-1675 cm À1 is probable due to the vibration of the carbonyl group of a benzoquinone and has to be taken into account as a second reaction pathway in the course of TYH + electrooxidation on platinum. Reports about the adsorption and electrooxidation of phenols and hydroquinones on platinum sc surfaces using ultra-high vacuum methodologies and conventional electrochemical techniques [42][43][44][45] have been published in the late 1980s. Either if there was a random orientation of the molecule at the surface or a defined adsorption (aromatic ring parallel or perpendicular orientation), the phenol or hydroquinone molecule produces quinone derivates in acid solution at a smooth or a rough platinum surface [46][47][48].…”

Please notehttp://www.link.springer.com Given Name E. The electrochemical behaviour of o-cresol in acidic medium on platinum electrode has been studied by cyclic voltammetry and in situ Fourier transform infrared spectroscopy. The o-cresol suffers hydrolysis during oxidation giving rise to the formation of methylp-benzoquinone. In situ FTIR spectroscopic studies also reveal the presence of CO2, formed as a consequence of the rupture of the aromatic ring. Moreover, the oxidation...
