Electrochemical deposition of up to a monolayer of on foreign substrates at potentials positive to the one (underpotential deposition) has been for some time. 1,2 It appeared interesting to see an electrochemically deposited layer of these adatoms, partial ionic character, 3,4 would affect the kinetics some electrochemical process compared to that at a electrode surface.
