Gerhard Ertl

for his studies of chemical processes on solid surfaces

2007

Page 22: Nobel Laureates in Chemistry

Gerhard Ertl

a gold medal

a diploma

10 million Swedish kronor

his 71st birthday

Page 23: Nobel Laureates in Chemistry

catalytic cleaning carbon monoxide oxidates on platinum

Freons reduce the ozone layer by reacting on the surfaces of small ice crystals,

rusting takes place when an iron surface is exposed to oxygen

electronics industry to manufacture semiconductor materials for components

artificial fertilizers contain ammonia which is produced when nitrogen and hydrogen react on an iron surface

renewable fuels can be produced using catalytic surfaces

Page 24: Nobel Laureates in Chemistry

The emergence of modern surface chemistry

The first to understand the potential of new technology

Methodological foundations for an entire field of research

High vacuum system and use of different technologies

Page 25: Nobel Laureates in Chemistry

Modern surface chemistry

Behavior of hydrogen on metal surfaces

- Produced in solar cells -catalysis

Nitrogen becomes an artificial fertilizer

- Haber-Bosch process

Page 26: Nobel Laureates in Chemistry

The Haber-Bosch process step-by-step

Page 27: Nobel Laureates in Chemistry

Surface measurement difficulties

Distinguish atomic/ molecular nitrogen

Spectroscopic methods

Photons or free electrons

- type of atoms - chemical environment

Structure of the surface

Page 28: Nobel Laureates in Chemistry

Nitrogen split takes longest

Adding potassium

Nitrogen split ammonia formation

Page 29: Nobel Laureates in Chemistry
