Topospecific Chemistry at Surfaces

Surfaces of solids exhibit different sites - a triviality. Even the simplest model, the ideal NaCl crystal, shows faces, edges, and corners. Different coordinative situations result in a different behaviour in all reactions. Of course, systems that are more complex contain a greater variety of different surface species. Finally, we should expect that in amorphous solids the topological situation of the surface is almost chaotic - apart from general restrictions given by the stoichiometry, bond lengths, and bond angles of the specific compound. 

Amorphous solids with large specific surface area play an important role in many chemical processes, especially as supports for heterogeneous catalysts. Therefore, the general problem is the behaviour of surface compoimds as a function of their individual topological situation that provides information of great practical value, e.g. for the modelling of catalysts.
