Electrocatalytic Methane Oxidation Greatly Promoted by Chlorine Intermediates

Angewandte Chemie International Edition, 2021
AbstractRenewable energy‐powered methane (CH4) conversion at ambient conditions is an attractive but highly challenging field. Due to the highly inert character of CH4, the selective cleavage of its first C−H bond without over‐oxidation is essential for transforming CH4 into value‐added products.

Electrocatalytic Oxidation of DNA-Wrapped Carbon Nanotubes

Journal of the American Chemical Society, 2005
The electrical properties of single-walled carbon nanotubes (CNT) are of intense interest due to applications in nanoelectronics. Cyclic voltammetry and chronoamperometry have been used to explore the Ru(bpy)32+ electrocatalytic oxidation of DNA-solubilized carbon nanotubes.

Mesoporous tin oxide for electrocatalytic CO2 reduction

Journal of Colloid and Interface Science, 2018
The increasing accumulation of CO2 in the atmosphere has been leading to serious environmental problems. Electrochemical reduction of CO2 is a potential means of carbon recycling for energy storage and environmental sustainability. However, it is limited by the lack of highly active and selective electrocatalysts. Here we demonstrate the development of

Electrocatalytic oxidation of nucleobases by TiO2 nanobelts

Physical Chemistry Chemical Physics, 2011
Two kinds of TiO(2) nanobelts were prepared from commercial P-25 powders via an alkaline hydrothermal method with and without an acid etching process. The uncauterized nanobelts (TNs) exhibited a smooth surface, and mixed phases of anatase and TiO(2) (B), whereas the cauterized ones (CTNs) displayed a rough surface and a pure anatase structure. TNs and

Recent Progress in Electrocatalytic Glycerol Oxidation

Energy Technology, 2020
Glycerol, as the major by‐product of biodiesel, can be oxidized into diverse value‐added chemical products via either traditional chemical methods or electrochemical routes. Electrocatalytic glycerol oxidation reaction (GOR) driven by renewable‐derived electricity (e.g., wind and solar) is a promising pathway for fine chemicals production.

Electrocatalytic Oxidation of Cellulose at a Gold Electrode

ChemSusChem, 2014
AbstractThe electrochemical properties of cellulose dissolved in NaOH solution at a Au surface were investigated by cyclic voltammetry, FTIR spectroscopy, the electrochemical quartz crystal microbalance technique, and electrochemical impedance spectroscopy. The reaction products were characterized by SEM, TEM, and FTIR and NMR spectroscopy. The results

Electrocatalytic alcohol oxidation by a molecular iron complex

Faraday Discussions, 2022
An efficient electrochemical method for the selective oxidation of alcohols to their corresponding aldehydes/ketones using a biomimetic iron complex, [(bTAML)FeIII–OH2]−, as the redox mediator in an undivided electrochemical cell with inexpensive carbon and nickel electrodes using water as an oxygen source is reported.

Electrocatalytic oxidation of ?-tyrosine by a nitroxide

Talanta, 2001
The electrochemistry of L-tyrosine was studied by cyclic voltammetry at a glassy carbon electrode. Although L-tyrosine itself showed very poor electrochemical response, the response could be greatly enhanced by using 4-hydroxy-2,2,6,6-tetramethylpiperidinyl-1-oxy (HO-TEMPO) as a mediator that enables a sensitive determination of the substrate.

Electrocatalytic oxidative cleavage by electrogenerated periodate

Journal of Molecular Catalysis A: Chemical, 2003
Abstract An electrocatalytic method has been developed for the indirect oxidation of vicinal diols and related compounds like hydroxyketones and aminoalcohols. The oxidative cleavage has been performed in a biphase system containing a phase transfer catalyst by periodate generated from iodate at a Pb-PbO2 electrode.

Electrocatalytic Oxidation of Glycerol on Platinum

The Journal of Physical Chemistry C, 2018
Glycerol, a surplus byproduct of biodiesel production, is a promising energy source for fuel cells. However, the low selectivity toward the complete-oxidation product, carbon dioxide (CO2), hinders the electro-oxidation of glycerol. In this work, we combine spectro-electrochemical studies of extended surfaces using sum frequency generation and product ...
