| 英文摘要 | A molecular-level insight into the nature of reactive oxygen species involved in dihydrogen (H-2) dissociation is of great importance to understand gold catalysis. In this study, laser ablation generated and mass-selected AuNbO4+ oxide cluster cations could dissociate H-2 in an ion-trap reactor. The reaction has been characterized by time-of-flight mass spectrometric experiments and density functional calculations. The lowest energy isomer of AuNbO4+ contains two lattice oxygen (O-2(-)) and one superoxide (O-2(center dot-)) species. The gold atom anchors the H-2 molecule in the first step and then delivers one hydrogen atom to the O-2(-) ion in H-2 dissociation. At the same time, O-2(-) is reduced into a peroxide unit that can accept the second hydrogen atom of H-2 with the generation of a hydroxyl radical as the main product. In this study, the important roles of the O-2(-) unit in the dissociation of H-2 have been identified. |
