The effect of chloride on the underpotential deposition of copper on Pt(111): AES, LEED, RRDE, and X-ray scattering studies

Functional links between stability and reactivity of strontium ruthenate single crystals during oxygen evolution

“…In general, it is very difficult to unambiguously distinguish between many different processes occurring during particular reaction, a typical example being metal deposition always accompanied by the simultaneous desorption of specific, adsorbed anions 51,52 . In the case of the OER, there are published rotating ring disk electrode (RRDE) results 53 that indicated that the OER on Ru always go together with Ru dissolution.…”

In situ scanning tunneling microscopy study of cobalt thin film electrodeposited on Pt(111) electrode

“…These features are ascribed to the two-electron redox reaction of Co 2+/0 . Judged from the higher peak current densities seen in chloride-containing solution, chloride anions could accelerate the reduction of cobalt ion, as noted previously for the reduction of copper ion [34,35]. Still, since the reduction peak D is 0.25 V more negative than the calculated Nernst potential of −0.57 V, a sizeable overpotential is needed to drive the reduction of Co 2+ at Pt and also at gold electrode [21].…”

Thermodynamic studies of chloride adsorption at the Pt(111) electrode surface from 0.1 M HClO4 solution

“…Molecular dynamics calculations have also been applied to simulate adsorption of Cl À at the charged water-platinum interface [20]. Anions are known to influence the metal underpotential deposition (upd) reaction [21] and there is a rich literature that describes the effect of chloride on upd phenomena at the Pt single crystal surfaces [22][23][24][25][26][27][28][29][30]. There are several new elements that this work brings to the knowledge of chloride adsorption at Pt.…”
