研究气态条件下异核氧化物团簇与小分子的反应,可从分子水平揭示多组分氧化物催化剂中的各组分在化学转化中的作用,为理性设计和氧化物催化剂改进提供理论基础。本文综述了异核氧化物团簇活化和转化小分子的研究新进展,讨论了异核掺杂引起的氧化物团簇局部电荷环境、局部自旋环境以及成键结构的变化对一些重要活性氧物种的反应性的调控,展示了氧化物团簇掺杂贵金属原子所带来的奇特化学反应以及新的反应机理。
Studying the reaction between heteronuclear oxide clusters and small molecules under gaseous conditions can reveal the role of each component of multicomponent oxide catalysts in chemical conversion at the molecular level and provide a theoretical basis for rational design and improvement of oxide catalysts . In this paper, the recent advances in the study of the activation and transformation of heteronuclear oxide clusters are reviewed. The effects of heteronuclear doping on the local charge environment, local spin environment and bonding structure of oxide clusters are discussed. Some important reactive oxygen species The regulation of the reactivity of the species shows the peculiar chemical reactions caused by the doping of the noble metal atoms with oxide clusters and the new reaction mechanism.
