Florian Schrenk ( left ) and Christoph Rameshan CO2 and methane can be turned into valuable products. But until now the catalysts required for such reactions quickly lose their effectiveness. TU Wien has now developed more stable alternatives. Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted into something useful: this approach is called "carbon capture and utilisation". Special catalysts are needed for this. Until now, however, the problem has been that a layer of carbon quickly forms on these catalysts - this is called "coking" - and the catalyst loses its effect. At TU Wien, a new approach was taken: tiny metallic nanoparticles were produced on perovskite crystals through special pre-treatment.
