✦ Synopsis

Copper is shown to deposit as a monolayer on to platinum at controlled potentials more positive than the potential at which it will deposit in bulk. An explanation is advanced in terms of the dflerences in free energy of the copper-platinum bond and the copper-copper bond. The chemisorption appears to take place about two main potentials and it is postulated that the difference between these may be associated with the difference in surface energy of two crystal faces of the platinum.

The results are correlated with the previous work on thallium and provide further evidence that the surface coverage can approach 100%.

It is shown that, as found for some other metals, bismuth can form a monolayer on the surface of the platinum at potentials which are somewhat more positive than the expected plating-out potential.
