分子尺度上水和金属表面的相互作用

Molecular interactions between water and metal surfaces

虽然水普遍存在,但人们在分子尺度上对水与固体表面的相互作用的理解却仍然处在初始阶段.文章简述了20年来人们对水在贵金属表面的吸附和浸润过程进行微观尺度上研究的进展,分析和讨论了水和表面作用的一般规律和所获得的经验教训,特别着重讨论了对上世纪80年代人们提出的经典双层冰模型的修正.

Water exists everywhere; despite this fact the molecular picture of water interaction with solid-state surfaces is poorly understood. Here we review the significant advances during the last two decades in our understanding at the microscopic level of water adsorption and wetting on the surfaces of precious metals. The microscopic behavior of water-surface interaction is analyzed and the lessons we have learned are discussed,with emphasis on the modifications to the ideal ＂ice bilayer＂ model originally proposed in the 1980s.
