Abstract

The easy reaction of primary alkyl iodides RI with palladium metal is used to transport elemental palladium onto solid cathodes (Glassy carbon, gold, platinum, nickel, etc.). The principle is to create suspensions of palladium particles in solutions of RI’s in aprotic polar solvents. Electroactive species are [R–Pd +, I −] that cover palladium grains and may discharge (according to a one-electron process) at electrified substrates for liberating Pd . This procedure efficiently produces palladium nano-aggregates and easily yields chemically modified surfaces with a large palette of substrates.
