Capacitance dispersion in EIS measurements of halides adsorption on Au(210)

Modelling water adsorption on Au(210) surfaces: II. Monte Carlo simulations

“…Once the scope of dissipation associated to phase transitions in the interface is still an open subject, molecular simulations of the Au(2 1 0)/water interface regarding the adsorption process can contribute to a better understanding of experimental results obtained by two of us [22][23][24][25]. The other motivation of the present paper is just to test the consistency of the results obtained by using the force field for that interface recently proposed by us [20].…”

“…It is therefore, in experimental terms, a stable surface for adsorption studies in the total range of the electrical double layer potential region. As a consequence, the Au(2 1 0) surface is a suitable choice, e.g., for the study of dissipative processes accompanying adsorption phenomena [22] and reorientations in the adsorbed solvent layer [23,24], since the reconstruction process itself is also a source of dissipation and may couple with adsorption dissipation, as in the case of halides adsorption onto Au(1 1 1) [25].…”

Corrosion Protection of AA7075 Aluminium Alloy by Trimethoxy-Silanes Self-Assembled Monolayers

“…For capacitance dispersion related to the film pseudocapacitive behaviour (CPE ), several studies have demonstrated links between dispersion and film morphological characteristics [60][61][62]. Otherwise, for the electrode/solution interfacial capacitance (CPE DL ), the dispersion is related to the heterogeneous dynamics of phase transitions in the interfacial region, as solvent molecules reorientation on the surface [63,64] and adsorption or reorganization of adsorbed layers [65][66][67], which are processes strongly influenced by the surface topography and energetic heterogeneity.…”

Monte Carlo Simulation of the Solvent Contribution to the Potential of Mean Force for the Phenol Adsorption on Au(210) Electrodes

“…The PMF may also provide additional information, especially in the cases of 2D transitions in the adsorbed layer or reorientation of the adsorbed molecules. Indeed, the understanding of the relaxations that take place during the processes is invaluable to probe dissipative phenomena at the interface [4][5][6][7]. In the case of phenol adsorption on noble metal electrodes, electrochemical studies [64] have shown that, at potential of zero charge (pzc), the phenol molecules adsorb parallel to the surface on polycrystalline gold.…”

“…For example, adsorption is involved in the mechanism of charge transfer reactions at electrode surfaces [1][2][3], capacitance dispersion in the electrode/solution interface [4][5][6][7][8][9][10] and self-assembly processes [11][12][13][14][15][16]. As such, adsorption is a crucial subject for various technologic research fields, ranging from surface modification [17][18][19] to heterogeneous catalysis applied to fuel cells [20][21][22].…”
