表面敏感光谱,最近扫描隧道显微镜,提供了一个新的见解,在金属表面的氧化学吸附的动力学。在低温下的研究,使用探针分子,提供了第一个证据的亚稳态的“热”氧瞬变和分子复合物的作用,在氧化催化打开低能量的途径。在过去15年的进展被认为是,强调的局限性,经典的方法在讨论的机制,表面反应和如何通过表面光谱发展的概念可以持续在原子分辨水平。
Surface sensitive spectroscopies, and more recently scanning tunnelling microscopy, have provided a new insight into the dynamics of oxygen chemisorption at metal surfaces. Studies at low temperatures, using probe molecules, provided the first evidence for the role of metastable “hot” oxygen transients and molecular complexes in opening up low-energy pathways in oxidation catalysis. Progress over the past 15 years is considered, emphasizing the limitations of the classical approach in discussions of the mechanisms of surface reactions and how concepts developed through surface spectroscopies could be sustained at the atom-resolved level.
