Dipole effect of (100) monatomic steps of gold n(111) × (100) vicinal faces in contact with aqueous solutions and under ultrahigh vacuum

Towards the understanding of the interfacial pH scale at Pt(1 1 1) electrodes

“…In the case of gold, particular care should be taken to control the nature of the surface structure since this can be easily altered by the surface reconstruction phenomena [7,17]. For gold and silver, a lot of information has been gathered about the influence of the surface structure [17][18][19][20][21], specific adsorption and temperature [22][23][24][25][26][27] on the potential of zero charge.…”

Coulostatic potential transients induced by laser heating of platinum stepped electrodes: influence of steps on the entropy of double layer formation

“…The influence of the structure of the electrode surface on the pzc has been addressed numerous times in the past [4][5][6][7][8][9][10][11][12][13]. This was done first for gold and silver electrodes where the pzc can be easily determined by identifying the position of the minimum in the differential capacity curve, according to the Gouy-ChapmanStern model of the double layer [4,5,[7][8][9].…”

Underpotential Deposition on Single-Crystal Metals

“…The residence of cations and/or anions depends on the double-layer potential, the sign and magnitude of which are determined by the position of the point-of-zero charge (pzc) of the electrode. Primarily, the position of the pzc changes with a change in the crystal face of the metal electrode; 148,180,181 the kind of adsorbed species and its coverage are changed with respect to the pzc. It is likely that the underpotentially deposited metal is directly bound to the substrate metal electrode, while the anions and/or solvent present at the electrode are substituted before the underpotential deposition.…”

“…147 This is supported by the work for determination of the point-of-zero charge of the Au single-crystal electrode. 148 Various discussions on the vacuum-scale potential of the standard hydrogen electrode are given in Ref. 146.…”
