Electrochemical Behavior of Carbon Electrodes for In Situ Redox Studies in a Transmission Electron Microscope

Vasiliki Tileli, Robin Pierre Alain Girod, Nikolaos Nianias

Electrochemical liquid cell transmission electron microscopy (TEM) is a unique technique for probing nanocatalyst behavior during operation for a range of different electrocatalytic processes, including hydrogen evolution reaction (HER), oxygen evolution r ...

Highly Active Nanoperovskite Catalysts for Oxygen Evolution Reaction: Insights into Activity and Stability of Ba0.5Sr0.5Co0.8Fe0.2O2+delta and PrBaCo2O5+delta

Nicola Marzari, Ivano Eligio Castelli, Xi Cheng

It is shown that producing PrBaCo2O5+delta and Ba0.5Sr0.5Co0.8Fe0.2O2+delta nanoparticle by a scalable synthesis method leads to high mass activities for the oxygen evolution reaction (OER) with outstanding improvements by 10x and 50x, respectively, compar ...

The MnO4–/MnO42– redox couple has a positive redox potential, high electrochemical reversibility and high solubility, up to 3.62 M at room temperature. Careful optimization of the electrolyte composition and the potential limits eliminates the side reactio ...

Royal Society of Chemistry2016

Hydrogen or hydrogen peroxide can be generated in liquid-liquid biphasic systems, where the organic phase contains sufficiently strong electron donor (whose redox potential is lower than the potential of reversible hydrogen electrode). H2O2 generation with ...

Electrocatalysis induced by surface redox activities on conductive metal oxide electrodes

Stéphane Fierro

Iridium dioxide electrodes form part of the dimensionally stable anodes (DSA®) and this electrode material is widely used in many industrial processes namely water electrolysis, metal electro-winning, cathodic protection and electro-organic synthesis due t ...

Electrochemical comparison between IrO2 prepared by thermal treatment of iridium metal and IrO2 prepared by thermal decomposition of H2IrCl6 solution

Christos Comninellis, Agnieszka Kapalka, Stéphane Fierro

The surface redox activities, the oxygen evolution reaction (OER), the oxidation of formic acid (FA) and the anodic stability have been investigated and compared on IrO2 electrodes prepared by two techniques: the thermal decomposition of H2IrCl6 precursor ...

Electrochemical Properties of the Supramolecular Assembly of Ruthenium(II)-bipyridine Complex with Single-Walled Carbon Nanotubes

Michael Graetzel, Shaik Mohammed Zakeeruddin, Ladislav Kavan

The supramolecular assembly of Ru-bipyridine complex, coded Z-907Na, with single-walled carbon nanotube (SWNT) exhibits unique redox behavior, which is applicable for the nanotube wiring of LiFePO4 (olivine). Cyclic voltammograms of thin films of Z-907Na/S ...

Electrochemical Society2009

The chemical-mechanical polishing process (CMP) is an essential part of the production of integrated circuits. Metal to be polished in the CMP reacts with the oxidants from the aqueous suspension (slurry) and the passive film is formed on the metal surface ...
