Professor Jens K. Nørskov: Catalysis for sustainable production of fuels and chemicals
The development of sustainable energy systems puts renewed focus on catalytic processes for energy conversion. We will need to find new catalysts for a number of processes if we are to successfully synthesize fuels and chemicals from solar or wind electricity. Insight into the way the catalysts work at the molecular level may prove essential to speed up the discovery process. The lecture will outline a theory of heterogeneous catalysis that allows a detailed understanding of elementary chemical processes at transition metal surfaces and singles out the most important parameters determining catalytic activity and selectivity. The insight can be used to define catalyst design rules and examples of their use will be given.

What a great talk! Jens Norskov is one of the most important scientists in heterogeneous catalysis and electrocatalysis. It's a great honor to hear him talk about the theory and its applications. Thanks, DTUdk for providing this amazing video! Bravo Stuff!

Enlightening talk : 1. Linear scaling based on the bond energies for adsorption of molecules is limiting, we need to understand what goes on on the other side of the active site. 2. By changing the structure of the active sites of catalyst, either by modification of their actual geometry or spin, we are able to have catalysts that can perform within the optimal region (of zero over potential and low heat loss). 3. Hypothetically (based on the computer simulation), graphene doped with transition metals (especially Pd, Rh, Ni) will make very good catalysts for CO2 reduction particularly because of the flexibility of the sites on the planar/uni-dimensional graphene sheet which makes it easier for CO2 to be able to attach. But who is gonna make this ? Thank you Professor Jens K. Nørskov.

Dear sir Please contact me I have discovered a very new amazing property of Graphene and I think produced Ammonia but I am not sure? because I do not have resources to examine the Gas that produced as I checked it did not behave like H2 order O.

Fantastic. I would like to see again his lecture at last year.. I watched it but it is deleted it. Can you upload it again?
Dear editor... When someone will explain the grafics DO NOT show something else, like his face or a poorly image of the whiteboard. Thank you
