Influence of argon ion beam etching and thermal treatment on polycrystalline and single crystal gold electrodes Au(100) and Au(111)

Autor: Manfred Zander, Harm Wulff, Fritz Scholz, Frank Frost, Paula Ahrens, Ulrich Hasse, Dietmar Hirsch

Publikováno v: Journal of Electroanalytical Chemistry. 832:233-240

The effect of argon ion beam etching and subsequent annealing on the surface morphology and electrochemical response of poly- and monocrystalline gold electrodes was studied with the help of scanning electron microscopy, cyclic voltammetry and measur

Impact of gold-1-decanethiol-SAM formation and removal cycles on the surface properties of polycrystalline gold and SAM quality

Autor: Jeyabharathi Chinnaya, Dana Thal, Ulrich Hasse, Paula Ahrens, Heike Kahlert

Publikováno v: Journal of Solid State Electrochemistry. 22:1149-1154

The impact of 1-decanethiol self-assembled monolayer (SAM) formation and removal cycles on polycrystalline Au surfaces and SAM quality was studied with the help of CV, DPV, Pb-UPD, STM, and AFM. The SAM removal was accomplished by dissolution with ox

Identification of low-index crystal planes of polycrystalline gold on the basis of electrochemical oxide layer formation

Autor: Paula Ahrens, Fritz Scholz, Ulrich Hasse, C. Jeyabharathi

Publikováno v: Journal of Solid State Electrochemistry. 20:3025-3031

The electrochemical oxidation of single-crystal gold surfaces has been well studied, and the exposed crystal planes can be reliably distinguished based on the peak potentials of oxide formation. However, the multiple oxidation peaks of polycrystallin

Oxygen electroreduction on polycrystalline gold electrodes and on gold nanoparticle-modified glassy carbon electrodes

Autor: Ulrich Hasse, Fritz Scholz, Chinnaya Jeyabharathi, Paula Ahrens

Publikováno v: Journal of Solid State Electrochemistry. 18:3299-3306

The oxygen reduction reaction (ORR) in acid media can be catalyzed on gold electrodes when the surface is activated by mechanical or electrochemical pretreatments. The activation is caused by increased surface roughness and defects, or asperities. Af
