铂钌团簇活化甲醇C-H和O-H键的理论研究
Theoretical Study of Methanol C-H and O-H Bond Activation by PtRu Clusters
摘要
Abstract
Density functional theory calculations were performed to study the mechanism and reactivity of methanol oxidation mediated by PtnRum (n+m=3, n≠0) clusters. The potential energy surfaces and pathways of the initial O―H and C―H bond activations were predicted. The results show that the activation of methanol proceeds preferential y along the C―H bond activation pathway. The calculated reactivity order was Pt2Ru>Pt3>PtRu2. Frontier molecular orbital analysis showed that the initial C/O―H bond activation is a proton transfer process. The solvent effect was also investigated. This study wil enable a deeper understanding of C/O―H bond activation and provide new ideas for catalyst selection and optimizing conditions for methanol activation.关键词
