Electrochemical reduction of oxygen catalyzed by Pseudomonas aeruginosa [PDF]

open access: yes, 2010
Pseudomonas aeruginosa has already been shown to catalyze oxidation processes in the anode compartment of a microbial fuel cell. The present study focuses on the reverse capacity of the bacterium, i.e. reduction catalysis. Here we show that P. aeruginosa

Bilirubin oxidase from myrothecium verrucaria physically absorbed on graphite electrodes. Insights into the alternative resting from and the sources of activity loss [PDF]

open access: yes, 2015
The oxygen reduction reaction is one of the most important chemical processes in energy converting systems and living organisms. Mediator-less, direct electro-catalytic reduction of oxygen to water was achieved on spectrographite electrodes modified by

Silver Decorated Reduced Graphene Oxide as Electrocatalyst for Zinc–Air Batteries

open access: yesEnergies, 2020
Due to their low cost and very high energy density, zinc−air batteries (ZABs) exhibit high potential for various energy applications. The electrochemical performance of the air-cathode has a decisive impact on the discharge performance of ZABs ...

Oxygen Hydration Mechanism for the Oxygen Reduction Reaction at Pt and Pd Fuel Cell Catalysts [PDF]

open access: yes, 2011
We report the reaction pathways and barriers for the oxygen reduction reaction (ORR) on platinum, both for gas phase and in solution, based on quantum mechanics calculations (PBE-DFT) on semi-infinite slabs. We find a new mechanism in solution: O_2 → 2O_(

Cross-linked CoMoO4/rGO nanosheets as oxygen reduction catalyst [PDF]

open access: yes, 2017
Development of inexpensive and robust electrocatalysts towards oxygen reduction reaction (ORR) is crucial for the cost-affordable manufacturing of metal-air batteries and fuel cells. Here we show that cross-linked CoMoO4 nanosheets and reduced graphene

Oxygen Reduction by Nitric-oxide Synthases [PDF]

open access: yesJournal of Biological Chemistry, 2001
Nitric-oxide synthases (NOS, EC 1.14.13.39) are hemeproteins that catalyze oxidation of L-arginine to NOz and L-citrulline. Three main isozymes exist in mammals that are regulated by distinct genes (1–6): a constitutive neuronal NOS (nNOS or NOS I), (7, 8), an endotoxinand cytokine-inducible NOS (iNOS or NOS II) (9, 10), and a constitutive endothelial ...

Synthesis of ultrathin platinum nanoplates for enhanced oxygen reduction activity. [PDF]

open access: yes, 2018
Ultrathin Pt nanostructures exposing controlled crystal facets are highly desirable for their superior activity and cost-effectiveness in the electrocatalytic oxygen reduction reaction (ORR), and they are conventionally synthesized by epitaxial growth of
