我们使用近环境压力（NAP）-XPS研究了当暴露于UHV至100 mTorr压力范围内的CO气体时，Pt（111）表面上形成的高密度CO吸附相。结合NAP-XPS测量和DFT计算的结果揭示了CO分子在致密CO覆盖层中的吸附结构，该结构在实际条件下是稳定的。
We investigated the high-density CO adsorption phase formed on a Pt(111) surface when exposed to CO gas of pressure ranging from UHV to 100 mTorr using near-ambient-pressure (NAP)-XPS. Combined results from the NAP-XPS measurements and DFT calculations reveal the adsorption structure of CO molecules in the dense CO overlayer, which is stable under realistic conditions.
