The first atomic-level video of a catalytic reaction reveals hidden pathways
Graphical abstract. Credit: Chem (2025). doi: 10.1016/j.chempr.2025.102541 For the first time, a team of university-led scientists in the northwest has directly observed catalytic catalysts at the atomic level. In a fascinating new video, a single atom moves and shakes during a chemical reaction that removes hydrogen atoms from alcohol molecules. By looking at the process in real time, researchers have…

Hydrogen’s dual nature helps reveal hidden catalytic processes
Credit: Nature Catalysis (2024). DOI: 10.1038/s41929-024-01262-w Microorganisms have long used hydrogen as an energy source. To do this, they rely on hydrogenases that contain metals in their catalytic centers. In order to use these biocatalysts for hydrogen conversion, researchers are working to understand the catalytic process. A team from three Max Planck Institutes (MPI), the Center for Neurodegenerative Imaging (BIN)…
