The nature of hydrated proton on solid surfaces is vital importance in electrochemistry, channels, and hydrogen fuel cells but remains unclear because the lack atomic-scale characterization. We directly visualized Eigen- Zundel-type protons within bonding water network Au(111) Pt(111) surfaces, using cryogenic qPlus-based atomic force microscopy under ultrahigh vacuum. found that Eigen cations self-assembled into monolayer structures with local order, Zundel formed long-range ordered...
Here, we develop an apparatus for preparing frozen solution samples, which can be characterized by surface science techniques under ultrahigh vacuum (UHV) conditions. When a temperature-controlled substrate makes contact with at 77 K, the of is locally melted and then refreezes together substrate. By detaching from in situ high vacuum, cleaved transferred onto Applying this method, demonstrate transferring NaCl LiNO3 solutions Au directly imaging crystallization atomic resolution using force...
