Abstract

Cluster models have been used to investigate the reaction of water on the surface of PbS (galena). The results from both semi-empirical and ab initiolevels of theory suggest that on a perfect {001} surface, water is a stable species and dissociation does not occur. However, at a small step-like feature the reaction PbS + H2O --> Pb(OH)(+) + HS- is exothermic with a sufficiently low barrier that a facile reaction occurs at ambient temperature.
