It was for work on the reactions at solid surfaces.
This kind of reactions are taking place for example in your car exhaust catalyst,
but they are also the basis for chemical industry -
- large processes in chemical industry are based on reactions at solid surfaces.
The phenomenon is called catalysis.
Catalysis is an effect that the presence of a third component, which is not consumed in the reaction,
is accelerating the progress of a reaction.
This very often takes place by interplay,
interaction between molecules from the gas phase and a solid surface,
where they are transformed into new compounds...
...and then leave the surface again so that the process can go on and on.
Understanding how these processes take place on an atomic or molecular level...
...is of course of importance for the ability to predict the reactivity of a certain process.
That was the work which was my lifetime attempt to understand how...
...chemical reactions at surfaces take place.
