“…The decrease of C1/A1 could be attributed either to loss of some CuEDTA 2À , owing to Cu x S(s) precipitation, or alternatively to the blocking effect of HgS on the electrode surface. The C2 peak represents the well-known processes of HgS(s) reduc- tion and sulfide desorption, and the A2 peak represents subsequent deposition of HgS(s) during the reverse scan [21][22][23][24][25][26][27]. This reaction is…”

“…Phase formation controlled by a charge transfer reaction Me n+ + ne − ↔ M across the interface, such as 2D electrocrystallization [114,115], UPD [2,22,116], and 2D anodic passivation [117,118] gives the following expression for G T…”

“…In the diffusionlimited aggregation model, proposed by Witten and Sander, the resulting cluster has an open structure with fractal dimensions of 1.66 [150]. More complex mechanisms involve anisotropic and/or multistep growth, induction periods of growth [117,133,[151][152][153][154], as well as defect-mediated processes [2,17]. The case of 1D growth was treated quantitatively in the formation of surface hemimicelles of amphiphils [155].…”

“…Beyond the niche substrate of single-crystal surfaces, which are typically somewhat exclusively studied, UPD can occur with liquid mercury electrodes leading to the formation of HgS monolayers. [45][46][47] It is not uncommon that UPD results in abnormally narrow and sharp voltammetry peaks. [42][43]45 To understand this, simulations accounting for surface interactions are necessary.…”

Phase transition behaviours are not uncommon in voltammetry owning to strong interactions on the surface. By coupling interfacial electrode kinetics with Frumkin adsorption isotherm, the underlining physicochemical processes occurring in voltammetry induced phase transition are studied via simulation herein. We report phase-transition-like behaviour is only observable in voltammetry under reversible electrode kinetic, which otherwise, would lead to a 'disconnection' from the Frumkin adsorption isotherm. In case when phase transition occurs in the timescale of voltammetry, the simulated interfacial conditions reveal intrusions into the 'forbidden' part predicted by the Frumkin adsorption isotherm, which is otherwise inaccessible to the prediction on the assumption of mass transport equilibrium, even if significant excess in bulk concentration is used.
