dc.description.abstract
Thiolate protected metal nanoclusters are emerging materials for the preparation of atomically defined heterogeneous catalysts. Recently it was revealed that the ligands migrated to the support upon cluster deposition, which influences the catalytic behaviour. Here we examined the role of the protecting thiolate ligands on the cyclohexane oxidation for Au₃₈(SR)₂₄ supported on CeO₂ and Al₂O₃. Sulfur containing products were detected. XANES S K-edge measurements revealed SOₓ species on the support during the reaction. The results indicate (i) an active and complex role of the thiolate ligand and (ii) changes of cluster (surface) structure, depending on support material and reaction conditions.
