Ethylene hydrogenation often serves as an example of a structure insensitive reaction. Here, the authors study the reaction, catalyzed by a range of size-selected platinum nanocatalysts, and demonstrate that in the sub-nanometer regime particle size

Transformation brought about by ligand exchange is one of the effective methods for the synthesis of gold-thiolate nanomolecules (AuNMs). In this method, the AuNMs are treated with an excess exogenous thiol at an elevated temperature. It has been fou

We report the results of a study of the isomeric thiolate monolayer capping of two gold nanocluster molecules, namely Au92 and Au102, both protected by 44 4-tert-butylbenzene thiolate (TBBT) ligands. The finding of an isomeric monolayer of the same l

Gas-phase ion-trap reactivity experiments and density functional simulations reveal that water oxidation to H2O2 mediated by (calcium) manganese oxide clusters proceeds via formation of a terminal oxyl radical followed by oxyl/hydroxy O-O coupling. T
