Pt(111)上的水:质子无序的重要性

Water on Pt(111): the importance of proton disorder

Luigi Delle Site, Luca M. Ghiringhelli, Oliviero Andreussi, Davide Donadio, Michele Parrinello

摘要:

用第一性原理计算方法研究了Pt(111)表面水吸附层的结构。只有考虑到质子无序,才能找到基态能量,这是水/金属化学键和水网络氢键之间相互作用的结果。由此产生的短O-Pt距离占实验证据。这些结果的新颖性揭示了水-金属相互作用的相关方面的新的光。

英文摘要:

The structure of a water adlayer on Pt(111) surface is investigated by extensive first principle calculations. Only allowing for proton disorder the ground state energy can be found. This results from an interplay between water/metal chemical bonding and the hydrogen bonding of the water network. The resulting short O-Pt distance accounts for experimental evidences. The novelty of these results shed a new light on relevant aspects of water-metal interaction.
