“…It has been also reported that the surface contains a non-negligible number of defects even after hydrogen cooling [40]. Regarding the surface structure, previous studies by ex situ low-energy electron diffraction [41][42][43] have shown that the (1×2) Pt(l10) surface is stable in perchloric and sulfuric acid solution if the potential is restricted to potentials below 0.7 V. There is no previous report based on in situ techniques that shows the presence of the (1×2) reconstruction of the Pt(110) in an electrochemical environment. If there were a fast potential-induced reconstruction, the conclusions about the stability range for Pt(110) could be wrong (like for Au(110) [43]) because the (1×2) structure could be formed back from (1×1) at the immersion potential.…”

Effect of the Surface Structure of Pt(100) and Pt(110) on the Oxidation of Carbon Monoxide in Alkaline Solution: an FTIR and Electrochemical Study

The electrochemical oxidation and infrared spectral features for carbon monoxide adsorbed on Pt(100) and Pt(110) in 0.1 M NaOH were studied as a function of the annealing/ cooling treatment with the objective to establish the influence of the platinum surface site geometry and the role of surface order in the electro-oxidation of CO on these two surfaces. Two common cooling methods (Ar and H 2 /Ar atmospheres) were employed for both surface electrodes. Additionally, CO cooling and I 2 vapour cooling methods were used for Pt(100) and Pt(110), respectively. Multiple CO vibration bands were observed on both electrode surfaces, their distribution and potential dependence strongly depending on the surface treatment.

First-principles calculations of clean Au(110) surfaces and chemisorption of atomic oxygen

We present detailed density-functional theory studies of the structures of clean Au͑110͒ surfaces and the energetics of various atomic oxygen coverages. Various ͑1 ϫ r͒ "missing row" reconstructions of the clean Au͑110͒ surface have been investigated. The surface energies of the clean reconstructed surfaces are found to be very close with an energy minimum for Au͑110͒-͑1 ϫ 3͒. The ͑111͒ microfacets formed at Au͑110͒-͑1 ϫ r͒ reconstructed surfaces with r Ͼ 1 allow further adsorption sites. Adsorption in pseudothreefoldcoordinated sites, along close-packed rows in the topmost gold layer, is favored over other adsorption sites. On Au͑110͒-͑1 ϫ r͒, adsorption energies are generally higher for these sites.

“…on the preparation conditions Moritz and Wolf could also stabilize well ordered (1 x 3) MR-superstructures on Au(110) [6] and Pt(ll0) [24], although it seems that these phases possibly are stabilized by impurities [72,73].…”

Reconstruction behaviour of fcc(110) transition metal surfaces and their vicinals

et al. 1992

Abstract. The fcc(ll0) surfaces are well known for their strong tendency to missing-row (MR) type reconstructions either in the clean state (Au, Pt) or driven by adsorbates (Ni, Cu, Pd, Ag). The present knowledge on the different reconstruction behaviour of flat (110) surfaces is reviewed. The survey focuses on recent scanning tunneling microscopy (STM) studies, which for the first time also elucidate the dynamics of the reconstruction process for the various systems. An overview of our recent STM and low energy electron diffraction studies on vicinal Au(ll0) and Ni(110) surfaces is given, aiming for a deeper understanding of the influence of steps on reconstruction behaviour of fcc(110) surfaces on the one hand, and on the stability of reconstructing vicinal surfaces on the other. Finally, we report on the reconstruction behaviour of Ir(110), which stabilizes in the clean state by formation of mesoscopic (331) facets and dereconstructs to the (1 x 1) phase upon oxygen adsorption at 700-900 K.
