Figure 1. Model for the processes during the synthesis of the nanoparticles on the particle level. A: Due to the high cathodic potential at the metal electrode the water is reduced at the phase transition, resulting in an anhydrous layer around the electrode. B: The metal of the electrode along with the cations of the electrolyte form the anionic metal species. The latter are oxidized to elementary metal by water in C and D. E: The generated nanoparticles are released from the electrode
