Heterogeneous catalysis

More than skimming the surface

The high temperatures and pressures used in heterogeneous catalysis make it difficult to observe catalysts using conventional techniques. Now, adsorbed product molecules on the surface of a single-crystal model catalyst have been observed during catalysis using a custom-built scanning tunnelling microscope that can work in situ.
