Electrochemical generation of solvated electrons from nanostructured carbon

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

“…Although a number of various electrochemical systems of nanosize were probed recently using different experimental technique (see, e.g., Refs. [28][29][30][31][32][33][34][35][36][37][38][39][40][41]), the authors investigated the averaged properties of arrays of carbon nanotubes and metal nanowires. Reliable kinetic measurements on a single nanosize electrode remain still an exceedingly complicated and challenging problem.…”

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

“…9 Eq. (8) is fulfilled in the region 0 ≤ x ≤ d H , where d H is the dense layer thickness; a value of 0.3 nm (close to the radius of a water molecule) for d H was used in further calculations.…”

“…According to our DFT calculations this sum amounts to 0.9. 9 Although the dielectric constants of the dense layer may be different for nanosize contacts and plain metal electrodes, this difference was neglected. numbers z and −z; ε 2 is the dielectric constant of diffusive layer (78 for aqueous solutions); ε 0 is the dielectric constant of vacuum.…”

“…In this context, metal nanowires and carbon nanotubes in contact with electrolyte solutions are a particularly interesting class of electrochemical systems, both from a theoretical and a practical point of view. Recently such interfaces have become the subject of experimental studies on the basis of electrochemical scanning probe techniques [1][2][3][4][5][6][7][8][9][10][11]. Thus, the adsorption of anions and organic molecules from electrolyte solutions at copper and gold nanowires was investigated by Tao et al [1][2][3].…”

“…Krivenko et al observed solvated electrons electrochemically generated from carbon nanotubes [9]. Using cyclic voltammetry the authors [3] studied redox properties of hemoglobin (Hb) immobilized onto the surface of CNT; the apparent heterogeneous electron transfer rate constant was estimated.…”
