Recycling greenhouse gases: Nanoparticles on perovskite crystals avoid 'coking' effect

Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted into something useful: this approach is called "carbon capture and utilization." 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.
