Electron transfer across a conducting nanowire (nanotube)/electrolyte solution interface

Bond breaking electron transfer across a conducting nanowire(nanotube)/electrolyte solution interface: The role of electrical double layer effects

“…The electron transfer kinetics in such electrochemical nanocontacts was theoretically addressed in Refs. [6][7][8]. Some qualitatively interesting features were predicted for a [Fe(CN) 6 ] 3À/4À redox couple in the vicinity of CNCs [7] (electrostatic catalysis, inverted Arrhenius plot) 1 ; noticeable catalytic effects were reported when considering the hydrogen oxidation on metal nanowires [8].…”

“…[7]. For the case of a charged conducting cylinder the following equation can be written to describe the potential distribution in the diffusive part of EDL:…”

“…(1) contains two contributions working in different potential scales [7]. The electrostatic potential u is zero at the potential of zero charge (PZC), which is a property of the electrode.…”

“…Therefore, it would be tempting to extend the approach developed in Refs. [7,8] to other redox processes. In this work we investigated the reduction of a peroxodisulphate anion (S 2 O 2À 8 ) at perfectly conducting nanocylinders.…”

Stability of Gold and Platinum Nanowires on Graphite Edges

“…In addition, there are a few theoretical papers on the basic physical properties (Leiva et al [8] ), on ionic adsorption (Frank et al [9] ), and outer-sphere electron transfer. [10] The important topic of the chemical reactivity and stability of such wires is largely unexplored.…”
