A Graphene Oxide and Copper-Centered Metal Organic Framework Composite as a Tri-Functional Catalyst for HER, OER, and ORR
TL;DR: A composite made from the assembly of graphene oxide (GO) and copper-centered metal organic framework (MOF) shows good performance as a tri-functional catalyst in three important electrocatalysis reactions, namely: the hydrogen evolution reaction (HER), oxygen evolution reaction, and oxygen reduction reaction (ORR) as discussed by the authors.
Journal ArticleDOI
Electrocatalysis of oxygen reduction and small alcohol oxidation in alkaline media
TL;DR: A critical review of several technologically important electrocatalytic systems operating in alkaline electrolytes, relevant to alkaline fuel cell (AFC) technology, and also relevant to chlor-alkali electrolysis and metal-air batteries.
Journal ArticleDOI
Oxygen reduction in nanoporous metal–ionic liquid composite electrocatalysts
TL;DR: It is shown that a tailored geometric and chemical materials architecture can further improve ORR catalysis by demonstrating that a composite nanoporous Ni-Pt alloy impregnated with a hydrophobic, high-oxygen-solubility and protic ionic liquid has extremely high mass activity.
Journal ArticleDOI
Structural effects in electrocatalysis: oxygen reduction on platinum low index single-crystal surfaces in perchloric acid solutions
TL;DR: Oxygen reduction was found to be sensitive to the crystallographic orientation of the platinum electrode surface as discussed by the authors, and a special cleaning procedure has been developed to remove impurities from the surface prior to the oxygen reduction measurements.

Electrode kinetics of oxygen reduction on oxide-free platinum electrodes☆
A. Damjanovic,V. Brusic +1 more
TL;DR: In this article, the cathodic V log i curves for O2 reduction on oxide-free Pt electrodes were determined in oxygen-saturated purified acid (HClO4, pH 1-3) and alkaline (NaOH, pH 13) solutions.
Journal ArticleDOI
Kinetics of oxygen evolution and dissolution on platinum electrodes
TL;DR: In this paper, the reaction mechanism in acid solution includes the primary water discharge as the rate-controlling step, while in alkaline solution, the mechanism changes and, for the same path, the primary discharge of OH− becomes the rate controlling step.

The Mechanism of Oxygen Reduction at Platinum in Alkaline Solutions with Special Reference to H 2 O 2
TL;DR: A rotating disk electrode with a concentric ring has been used to determine the role of hydrogen peroxide in the reduction of oxygen at platinum electrodes in alkaline solution as discussed by the authors, and the possible paths for oxygen reduction to water without peroxide intermediates are discussed in the light of already proposed mechanisms for the reduction at prereduced and preoxidized electrodes.

A Generalized Expression for the Tafel Slope and the Kinetics of Oxygen Reduction on Noble Metals and Alloys
TL;DR: In this article, the Tafel slope was modified to take into account the potential which is effective in charge transfer within the double layer, and possible paths and rate-determining steps were suggested for the cathodic reduction of oxygen.
