Catalysts: worth taking a closer look

Catalysts: worth taking a closer look

Metal surfaces play a role as catalysts for many important applications – from fuel cells to the purification of car exhaust gases. However, their behaviour is decisively affected by oxygen atoms incorporated into the surface. This phenomenon has been known for a long time, but until now it has been impossible to precisely investigate the role of oxygen in complex surfaces point by point in order to understand the chemical background at the atomic level.
