研究气态条件下原子团簇在完全可控、可重复条件下与CO的反应,可以在分子水平上理解CO的氧化,本综述对这些团簇研究工作进行了一些分析和总结,讨论了团簇研究方法的特点、 CO氧化的新见解以及有待解决的问题。
Carbon monoxide binds to hemoglobin much more tightly than does molecular oxygen, so CO is highly tox-ic to humans and animals. Oxidation of CO into CO2 is a major solution to removal of carbon monoxide in air purifica-tion. CO is also a simple molecule and CO oxidation serves as a prototypical reaction for heterogeneous processes. Atomic clusters composed of limited numbers of atoms are experimentally and theoretically tractable models for hetero-geneous catalysis. During the last decade, a number of publications have been devoted to understanding the CO oxi-dation at a molecular level based on the investigations of gas phase atomic clusters under controlled and well reproduc-ible conditions. In this review, we will go through the reported CO oxidations by gas phase atomic clusters. Advanta-ges, new insights, and problems to be solved involved with the cluster approach for the title reaction will be summa-rized.
