Real-time imaging to track catalyst formation
Nanomaterial-based catalysts are usually heterogeneous catalysts broken up into nanoparticles to speed up the catalytic process. Compared to their bulk counterparts, metal nanoparticles have a higher surface area, so there is increased catalytic activity. So far, the spectroscopic characterisation of materials undergoing reaction coupled simultaneously with measurement of catalytic activity and selectivity has been conducted in ideal conditions. The ambition of the EU-funded CARINE project is to track in situ and operando the structural evolution of catalytic nanoparticles in realistic conditions. It will do so by using coherent diffraction imaging. The new imaging technique will help researchers better understand catalyst formation and further improve their durability and efficiency.
