摘要：

We have used the Sutton-Chen potential to study the adsorption of platinum on graphite walls. The platinum-carbon interaction is assumed to be of Lennard-Jones' type and we have derived a set of potential parameters for this interaction from the Sutton-Chen potential. The results of the simulations using these potential functions are found to be in qualitative agreement with experimental studies. However, the size of the system should be sufficiently large in order to obtain realistic results. These findings indicate that these potential functions can be used to study this system more thoroughly.
