Electrochemical double layers (EDL) form at electrified interfaces. Whereas the Gouy–Chapman model describes moderately charged EDL, the formation of Stern layers was predicted for highly charged EDL. Our results provide structural evidence for a Stern layer of cations at potentials close to hydrogen evolution in alkali fluoride and chloride electrolytes. Layering was observed by X-ray crystal truncation rods and atomic-scale recoil responses of Pt(111) surface layers. Ordering in the layer was confirmed by glancing-incidence in-plane diffraction measurements.

电化学双层中的分层和有序

电化学双层(EDL)在带电界面处形成。尽管Gouy-Chapman模型描述了中等电荷的EDL,但预测到斯特恩层的形成将导致高电荷的EDL。我们的结果为阳离子斯特恩层提供了结构上的证据,该阳离子层的电位接近于碱性氟化物和氯化物电解质中的氢释放。通过X射线晶体截断杆和Pt(111)表面层的原子级反冲响应观察到分层。通过扫掠入射面内衍射测量来确认层中的有序性。
