It was for work on the reactions at solid surfaces. |
| 00:06 → 00:12 |
This kind of reactions are taking place for example in your car exhaust catalyst, |
| 00:12 → 00:15 |
but they are also the basis for chemical industry - |
| 00:15 → 00:20 |
- large processes in chemical industry are based on reactions at solid surfaces. |
| 00:20 → 00:24 |
The phenomenon is called catalysis. |
| 00:24 → 00:32 |
Catalysis is an effect that the presence of a third component, which is not consumed in the reaction, |
| 00:32 → 00:36 |
is accelerating the progress of a reaction. |
| 00:36 → 00:39 |
This very often takes place by interplay, |
| 00:39 → 00:43 |
interaction between molecules from the gas phase and a solid surface, |
| 00:43 → 00:46 |
where they are transformed into new compounds... |
| 00:46 → 00:51 |
...and then leave the surface again so that the process can go on and on. |
| 00:51 → 00:56 |
Understanding how these processes take place on an atomic or molecular level... |
| 00:56 → 01:04 |
...is of course of importance for the ability to predict the reactivity of a certain process. |
| 01:04 → 01:11 |
That was the work which was my lifetime attempt to understand how... |
| 01:11 → 01:14 |
...chemical reactions at surfaces take place. |
