Electrochemical Oxidation of Benzene to Phenol

Angewandte Chemie International Edition, 2011
Gas-phase electrochemistry: The direct hydroxylation of benzene to phenol was investigated using an electrochemical cell. The production of phenol over a VO(x) anode was found to be significant at 50 °C. The resultant current efficiency for phenol production and selectivity toward phenol reached 76.5 and 94.7 %, respectively.

An Electrochemical Route to Graphene Oxide

Journal of Nanoscience and Nanotechnology, 2011
Large-scale graphene oxide (GO) with adjustable resistivity was synthesized from graphite via an electrochemical method using KCl solution as an effective electrolyte. During the exfoliation process, electrostatic force intercalates chloride ions between the expanded graphite layers on the anode.

Electrochemical Oxidation of Chlorpromazine Hydrochloride

Journal of Pharmaceutical Sciences, 1964
The electrolytic oxidation of chlorpromazine hydrochloride has been studied. Controlled potential coulometry has shown the chlorpromazine undergoes a two-electron oxidation in dilute aqueous acid media. In 9 N sulfuric acid two successive one-electron oxidations, involving a stable semiquinone free radical intermediate, are identifiable ...

Electrochemical oxidation of selenocystine and selenomethionine

Colloids and Surfaces B: Biointerfaces, 2009
Electrochemical oxidation of selenocystine (SeCys) and selenomethionine (SeMet), on a gold electrode was studied by cyclic voltammetry (CV), rotating disk electrode technique (RDE) and chronocoulometry (CC). In 0.2 mol/L HAc-NaAc (pH=3.90) supporting electrolyte, anodic peak I potential of SeCys and SeMet was 810 mV and 638 mV, respectively, and this ...

Electrochemical oxidation of tannery wastewater

Journal of Chemical Technology & Biotechnology, 2001
AbstractTannery wastewater was treated by an electrochemical oxidation method using Ti/Pt, Ti/PbO2 and Ti/MnO2 anodes and a Ti cathode in a two‐electrode stirred batch reactor. The changes in colour concentration, chemical oxygen demand (COD), ammonia (NH4+), sulfide and total chromium have been determined as a function of treatment time and applied ...

Unusual electrochemical oxidation of cholesterol

Steroids, 2008
It has been found that cholesterol undergoes direct electrochemical oxidation on platinum electrode in dichloromethane. Voltammetric measurements show that the process is controlled by the rate of electron transfer and the height of the oxidation peak is linear vs. concentration of cholesterol.

Electrochemical oxidation of benzyl germatranes

Journal of Organometallic Chemistry, 2008
Abstract The electrooxidation of ring-substituted bromobenzylgermatranes in CH 3 CN and DMF solutions was studied. By cyclic voltammetry supported by DFT B3LYP/6-311G calculations, donor activity of the nitrogen atom was shown to be substantially reduced because of the dative N → Ge coordination compared to Et 3 N and (HOCH 2 CH 2 ) 3 N.

Electrochemical Oxidation

Electrochemical oxidation (EO) is able to mineralize poly- and perfluoroalkyl substances (PFAS) through potential-driven electron transfer in concert with reactions with reactive species on the anode surface. Performance of EO treatment hinges on the properties of the anode materials, the target PFAS, and the electrolytes, as well as the water quality ...

Electrochemical Oxidation of Methane to Methylamine

Journal of the American Chemical Society
The electrochemical methane (CH4) oxidation reaction under ambient conditions is a promising approach for natural gas utilization. However, the highly stable nature of CH4 restrains efficient cleavage of the C-H bond without overoxidation. To this end, we proposed a coupled oxidative strategy for converting CH4 to value-added products via NH2 ...

Effect of the electrochemical oxidation/reduction cycle on the electrochemical capacitance of graphite oxide

Carbon, 2014
Abstract Reduction largely affects the properties of graphene oxide (GO), because the content of each functional group changes by the oxidation degree. So far no study about re-oxidation and re-reduction of GO has been carried out. Herein, we report the effects of oxidation/reduction cycle of graphite oxide (GtO, multilayered GO) on its composition ...
