application.wiley-vch.deHeterogeneous Catalysis In heterogeneous catalysis, solids catalyze reactions of molecules in gas or solution. As solids – unless they are porous – are commonly impenetrable, catalytic reactions occur at the surface. To use the often expensive materials (e.g. platinum) in an eco-

The scientific field of classical Surface Science - introduced among others, by Gerhard Ertl - can be most successfully applied.
