Zeolite‐Stabilized Di‐ and Tetranuclear Molybdenum Sulfide Clusters Form Stable Catalytic Hydrogenation Sites

Supercages of faujasite (FAU)‐type zeolites serve as a robust scaffold for stabilizing dinuclear (Mo(2)S(4)) and tetranuclear (Mo(4)S(4)) molybdenum sulfide clusters. The FAU‐encaged Mo(4)S(4) clusters have a distorted cubane structure similar to the FeMo‐cofactor in nitrogenase. Both clusters posse...

description Supercages of faujasite (FAU)‐type zeolites serve as a robust scaffold for stabilizing dinuclear (Mo(2)S(4)) and tetranuclear (Mo(4)S(4)) molybdenum sulfide clusters. The FAU‐encaged Mo(4)S(4) clusters have a distorted cubane structure similar to the FeMo‐cofactor in nitrogenase. Both clusters possess unpaired electrons on Mo atoms. Additionally, they show identical catalytic activity per sulfide cluster. Their catalytic activity is stable (>150 h) for ethene hydrogenation, while layered MoS(2) structures deactivate significantly under the same reaction conditions.
