"The deposit of very small silver particles onto a very large palette of solid electronic conductors was achieved by means of the cathodic reduction of alkyl iodides RIs in the presence of a suspension of silver-palladium alloy particles (diameter > 250 mu m). The potential applied to the conductor is so that RIs are not directly reduced at its surface," researchers in Rennes, France report.
"The observed cathodic reaction is then the discharge of silver grains reacted in surface and covered by a transient assigned to be [RAg+, I-]. The main heterogeneous products are homo-dimers R-R while the deposition of silver aggregates of very small size (nanometric scale) ...
