Au(111) and Pt(111) surface phase behavior

Surface Science Letters, 1993
Abstract We describe our recent X-ray scattering studies of the structure and phases of the clean Au(111) and Pt(111) surfaces. Below 0.65 of their respective bulk melting temperatures, the Au(111) surface has a well-ordered chevron reconstruction and the Pt(111) surface is unreconstructed.

Xanthine Quartets on Au(111) [PDF]

Journal of the American Chemical Society, 2017
The quartet of xanthine (X), a purine base ubiquitously distributed in most human body tissues and fluids, has been for the first time fabricated and visualized, as the first alternative purine quartet besides the known guanine (G)-quartet. The X-quartet network is demonstrated to be the most stable phase on Au(111).

In-situ STM study of phosphate adsorption on Cu(111), Au(111) and Cu/Au(111) electrodes [PDF]

Surface Science, 2013
Abstract The interaction of Cu(111), Au(111) and Cu-covered Au(111) electrodes with a neutral phosphate buffer solution has been studied by means of cyclic voltammetry (CV) and in situ electrochemical scanning tunneling microscopy (EC-STM). Under low potential conditions, both the Cu(111) and the Au(111) surface appear apparently adsorbate free ...

Structure determination of Au on Pt(111) surface:LEED, STM and DFT Study [PDF]

, 2015
Low-energy electron diffraction (LEED), scanning tunneling microscopy (STM) and density functional theory (DFT) calculations have been used to investigate the atomic and electronic structure of gold deposited (between 0.8 and 1.0 monolayer) on the Pt(111)

Cyclotrimerization of arylalkynes on Au(111)

Chem. Commun., 2014
Cyclotrimerization of arylalkynes on Au(111) proceeds readily at modest temperatures, and affords two-dimensional covalently bonded polyphenylene networks.

The interface structure of n-alkylthiolate self-assembled monolayers on coinage metal surfaces [PDF]

, 2008
The current state of understanding of the structure of the metal/thiolate interface of n-alkylthiolate self-assembled monolayers (SAMs) on Cu(111), Ag(111) and Au(111) is reviewed. On Cu(111) and Ag(111) there is now clear evidence that adsorbate-induced

Borophene Synthesis on Au(111)

ACS Nano, 2019
Borophene (the first two-dimensional (2D) allotrope of boron) is emerging as a groundbreaking system for boron-based chemistry and, more broadly, the field of low-dimensional materials. Exploration of the phase space for growth is critical because borophene is a synthetic 2D material that does not have a bulk layered counterpart and thus cannot be ...

Activated Dissociation of HCl on Au(111)

The Journal of Physical Chemistry Letters, 2016
We report zero-coverage reaction probabilities (S0) for HCl dissociative adsorption on Au(111) obtained by the seeded molecular beam hot-nozzle method. For measurements at normal incidence with mean translational energies ranging from 0.94 to 2.56 eV (nozzle temperatures 296 to 1060 K), S0 increased from 6 × 10(-6) to 2 × 10(-2). S0 also increased with

O 2 reduction by lithium on Au(111) and Pt(111)

The Journal of Chemical Physics, 2010
Lithium-oxygen has one of the highest specific energies among known electrochemical couples and holds the promise of substantially boosting the specific energy of portable batteries. Mechanistic information of the oxygen reduction reaction by Li (Li-ORR) is scarce, and the factors limiting the discharge and charge efficiencies of the Li-oxygen cathode ...
