Danish researchers design the first virtual nano-catalyst in the world

31.01.2005


Research offers new opportunities in the fields of renewable energy, pollution control and in the chemical industry.



On January 28th 2005 Science features a paper by researchers from the Technical University of Denmark (DTU) and Haldor Topsøe A/S. The paper demonstrates that by applying the quantum theory you can calculate the performance of catalysts to be used in everything from cars to the future production of hydrogen.

So far the development of new catalysts have been based on very expensive experiments where you test a myriad of different substances. The research now published in Science forms a whole new scientific basis for the understanding of catalytic processes, and consequently for the development of new technology.


”This research is a perfect example of how in the field of nano-technology the gap between basic research and industrial production is very short indeed.” says the Chairman of Nano•DTU, professor Jens Nørskov.

Catalysis forms the basis of more than 20% of the world’s industrial production as well as a whole range of technologies that work towards creating a safer environment. One example is the catalytic converters that remove most of the pollution from today’s cars. We still need to design even better catalysts to remove more pollution from e.g. the exhaust from diesel engines.

The results of the scientists open the way towards designing new effective energy technologies. The production of hydrogen and fuel cells are thus directly dependent on the catalytic processes that we can now create models for – atom by atom.

According to Director of Research, Jens Rostrup-Nielsen from Haldor Topsøe A/S the researchers’ discovery proves ”that by intelligently using the advanced calculations which we are able to perform today, we will soon be capable of reducing the number of experiments necessary to develop new heterogeneous catalysts”.

Professor Jens Nørskov and his group including Dr. Karoliina Honkala (now at the University of Jyväskylä, Finaland) and Dr. Ioannis Remediakis (now at the University of Crete, Greece) at the Department of Physics at DTU have developed new theoretic approaches based on quantum physics, enabling them to predict the catalytic activity for any catalyst. Together with professor Claus Hviid Christensen of the Department of Chemistry at DTU and researchers at Haldor Topsøe A/S, headed by Dr. Søren Dahl, the calculations have been tested in detailed experiments on technical catalysts made up of nanometer sized metallic particles.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
