Jens Nørskov: A Pioneer in Theoretical Catalysis
Background and Academic Career
Jens Kehlet Nørskov is a Danish physicist and professor known for his work in computational catalysis and materials science. He earned his Ph.D. from Aarhus University in 1979 and has held prominent positions at institutions such as the Technical University of Denmark (DTU), Stanford University, and the SLAC National Accelerator Laboratory.
Nørskov is widely recognized for developing theoretical frameworks that predict the activity of catalysts, particularly in heterogeneous catalysis and electrocatalysis. His work has bridged the gap between fundamental science and industrial applications.
Key Contributions
1. The d-Band Center Theory
One of Nørskov’s most influential contributions is the d-band center theory, which explains how the electronic structure of transition metals influences their catalytic activity. The theory posits that the position of the d-band electrons relative to the Fermi level determines a metal’s ability to adsorb and activate molecules like CO, O₂, and H₂. This insight has been crucial in designing better catalysts for reactions such as:
- Ammonia synthesis (Haber-Bosch process)
- Hydrogen fuel cells (oxygen reduction reaction)
- CO₂ reduction for sustainable fuel production
2. Computational Catalyst Design
Nørskov and his team have used density functional theory (DFT) to screen thousands of potential catalyst materials, accelerating the discovery of new alloys and compounds. His group developed the Computational Materials Repository (CMR), a database of catalytic properties that serves as a valuable resource for researchers worldwide.
3. Sustainable Energy Applications
Nørskov has worked extensively on renewable energy technologies, including:
- Electrochemical CO₂ reduction to produce fuels
- Hydrogen evolution reaction (HER) for green hydrogen production
- Nitrogen reduction reaction (NRR) for sustainable ammonia synthesis
His research has inspired the development of cheaper, more efficient alternatives to precious metal catalysts like platinum.

Neurock has explored catalytic strategies for converting CO₂ into valuable chemicals, such as:
- CO₂ electroreduction to ethylene and ethanol
- Photocatalytic and thermocatalytic CO₂ utilization
- Bimetallic and nanostructured catalysts for improved selectivity
His simulations help identify key intermediates and transition states, enabling the rational design of catalysts.
