New methods of controlled monolayer-to-multilayer deposition of Pt for designing electrocatalysts at an atomic level

Autor: J. X. WANG, R. R. ADZIC, S. R. BRANKOVIC

Publikováno v: Journal of the Serbian Chemical Society, Vol 66, Iss 11-12, Pp 887-898 (2001)

Two new methods for monolayer-to-multileyer Pt deposition are presented. One involves Pt deposition by the replacement of an UPD metal monolayer on an electrode surface and the other the spontaneous deposition of Pt on Ru. The first method, exemplifi

Unusual Adsorption Properties of Silver Adlayers on the Pt(111) Electrode Surface

Autor: R. R. Adzic, J. S. Marinkovic, Nebojsa S. Marinkovic, J. X. Wang

Publikováno v: The Journal of Physical Chemistry B. 103:139-144

Adsorption properties of silver monolayer and bilayer deposited at underpotentials on a Pt(111) electrode were studied by means of linear sweep voltammetry, in situ surface X-ray scattering and infrared spectroelectrochemistry. Surface X-ray scatteri

In-Situ X-ray Diffraction and STM Studies of Bromide Adsorption on Au(111) Electrodes

Autor: Ben Ocko, Olaf M. Magnussen, Jia X. Wang, R. R. Adzic

Publikováno v: The Journal of Physical Chemistry. 100:5500-5508

The structure of bromide adlayers at the Au(111)−aqueous solution interface has been studied by in-situ surface X-ray scattering (SXS) and scanning tunneling microscopy (STM). Both techniques show the existence of a hexagonal close-packed adlayer p

Structure of Electrode Surfaces in the Course of Electrocatalytic Reactions: Oxidation of CO, Glucose, and Formaldehyde on Reconstructed and Unreconstructed Au(100)

Autor: R. R. Adzic, Olaf M. Magnussen, B. M. Ocko, Jia X. Wang

Publikováno v: Langmuir. 12:513-517

Grazing incident angle X-ray diffraction and linear sweep voltammetry were used to determine structure and reactivity of the Au(100) surface during the course of glucose, CO, and formaldehyde oxidations. The potential dependence of the diffracted int

Structure of Tl Adlayers on the Pt(111) Electrode Surface: Effects of Solution pH and Bisulfate Coadsorption

Autor: Jia X. Wang, R. R. Adzic, B. M. Ocko, Olaf M. Magnussen

Publikováno v: The Journal of Physical Chemistry. 100:14721-14725

The structure of Tl adlayers deposited at underpotentials on Pt(111) has been investigated in four different electrolyte solutions (HClO4, NaClO4, NaOH, and H2SO4) with surface X-ray scattering (SXS) techniques. In all solutions investigated, Tl form

X-ray diffraction studies of ordered chloride and bromide monolayers at the Au(111)-solution interface

Autor: Jun Wang, Olaf M. Magnussen, R. R. Adzic, Ben Ocko

Publikováno v: Physical Review B. 51:5510-5513

We present in situ surface x-ray scattering observations of ordered chloride and bromide monolayers on Au(111) electrodes in aqueous solutions as an example of in situ x-ray diffraction from adsorbates of the lighter elements (Z50). At a critical sur

X-ray Scattering Study of Tl Adlayers on the Au(111) Electrode in Alkaline Solutions: Metal Monolayer, OH- Coadsorption, and Oxide Formation

Autor: R. R. Adzic, Jia X. Wang, B. M. Ocko

Publikováno v: The Journal of Physical Chemistry. 98:7182-7190

Underpotential deposition (UPD) refers to theelectrodeposition of metals at potentials positive of the Nernst potential. It occurs when the adatom-substrate bonding is stronger than the adatomadatom bonding in the bulk phase.' On single crystal elect
