Determination of the platinum and ruthenium surface areas in platinum-ruthenium alloy electrocatalysts by underpotential deposition of copper. I. Unsupported catalysts
TL;DR: In this article, the potential deposition of copper has been used to characterize platinum, ruthenium, and platinum−ruthensium high-surface-area unsupported (powder black) electrocatalysts.
Journal ArticleDOI
Pt–Ru electrocatalysts for fuel cells: a representative review
TL;DR: In this article, the main idea of the review is to balance various aspects of Pt-Ru electrochemistry related to material science and electrocatalysis as well as to remember the early basic results being of importance for future understanding of Pt−Ru functional properties.
Journal ArticleDOI
Electrodeposition of Copper Thin Film on Ruthenium A Potential Diffusion Barrier for Cu Interconnects
TL;DR: In this article, the electrochemical deposition of copper (Cu) thin film on polycrystalline ruthenium (Ru) electrode surface was investigated in a sulfuric acid plating bath.
Journal ArticleDOI
Seedless superfill: Copper electrodeposition in trenches with ruthenium barriers
TL;DR: In this article, a single-step deposition of fine trenches by direct copper electrodeposition onto a ruthenium banier was demonstrated, where the ruthensium layer, as well as an adhesion promoting titanium or tantalum layer, was deposited by physical vapor deposition onto patterned silicon dioxide.

TL;DR: In this paper, the authors show that the Cu nucleation and growth mode is sensitive to the oxidation state of the Ru surface as well as the copper deposition parameters, and that early film coalescence is favored by deposition at high (η -0.25 V) overpotentials.

Electrocatalysis by ad-atoms: Part II. Enhancement of the oxidation of methanol on platinum by ruthenium ad-atoms
Masahiro Watanabe,Satoshi Motoo +1 more
TL;DR: The ad-electrode has the same electrocatalytic characteristics as the alloy electrode for the oxidation of methanol on the Ru-Pt catalyst system as discussed by the authors.
Journal ArticleDOI
Work function, electronegativity, and electrochemical behaviour of metals
TL;DR: In this article, it was shown that the best relationship between the two above quantities is expressed by the equations: E z =−4.61 −0.40 α, where α=(2.10−x M )/0.6 is defined as the degree of orientation of water at the interface.
Journal ArticleDOI
Underpotential deposition of metals and work function differences
TL;DR: In this article, the potential difference between monolayer and bulk deposition is closely related to the difference in the work functions of substrate and deposit, causing a partial charge of the adatoms.

Electrocatalysis by ad-atoms
Masahiro Watanabe,Satoshi Motoo +1 more
TL;DR: In this paper, the surface composition of Au-Pt and Au-pd alloy electrodes has been investigated for methanol oxidation and the results indicate that surface composition plays predominant roles in the methenol oxidation.
