We couple the kinetic modeling of the oxygen reduction process with experiments on patterned microelectrode cathodes for analyzing the electrochemical im-pedance spectroscopy (EIS) response to investigate ORR. 2 * 1.

Chemistry Department, State University of New York (SUNY) at Stony Brook, Stony Brook, NY 11794 (USA) 2 . … The oxygen reduction reaction (ORR) is undoubtedly the most important fuel‐cell cathodic reaction. Our first principles QM used the PBE flavor of density functional theory (DFT) to study the binding site preference, unit reaction pathways, and overall mechanisms on the closest packed surface of various metal surfaces. We study the oxygen reduction reaction (ORR) mechanism on a Pt(1 1 1) surface using density functional theory calculations. Oxygen reduction and hydrogen peroxide reduction are technologically important reactions in energy-conversion devices.

Mechanism of Oxygen Reduction Reaction on Pt(111) in Alkaline Solution: Importance of Chemisorbed Water on Surface. Shizhong Liu. … The oxygen reduction reactions (ORR) on La1-xSrxMnO3-d (LSM) are not well understood at the molecular level. In this work, a detailed electrochemical analysis of the ORR on Pt (111) in nonadsorbing electrolytes was performed, which included the high‐potential region E up =1.15 V while ensuring the electrode surface structure stability. The change in mechanism is assumed to be a switch from four‐electron reduction of oxygen to water to a two‐electron reduction to hydrogen peroxide followed by disproportionation of the hydrogen peroxide to water and oxygen.

Oxygen reduction reaction (ORR) is investigated on bulk PdO-based catalysts (oxides of Pd and Pd3Co) in oxygen-saturated 0.1 M HClO4 to establish the role of … Chemistry Department, Brookhaven National Laboratory, Upton, NY 11973 (USA) * To whom … Our first principles QM used the PBE flavor of density functional theory (DFT) to study the binding site preference, unit reaction pathways, and overall mechanisms on the closest packed surface of various metal surfaces. Optimizing oxygen-reduction and -evolution reactions is crucial for improving fuel cell efficiency, but the reaction is poorly understood at the nanoscopic level.
