METHANOL ELECTROOXIDATION WITH Cu-B CATALYST

INFRASTRUKTURA I EKOLOGIA TERENÓW WIEJSKICH / INFRASTRUCTURE AND ECOLOGY OF RURAL AREAS, 2016
In the last few years alternative energy sources have been fast developing. One of these sources is fuel cell. Due to development of the renewable energy sources, the powering of fuel cells with bio-fuels is very important. The one of this fuel is methanol.

Pyrrhotite Electrooxidation in Acid Solutions

Russian Journal of Electrochemistry, 2001
The electrooxidation of pyrrhotite, including that preliminarily etched in acid solutions, is studied by voltammetry, scanning electron microscopy, and X-ray electron spectroscopy. The oxidation mechanism includes the formation; “reversible” oxidation (which predominantly involves an increase in the amount of polysulfide ions) of a near-surface ...

Electrooxidation of Organics in Waste Water

SAE Technical Paper Series, 1990
<div class="htmlview paragraph">Electrooxidation is a means of removing organic solutes directly from waste waters without the use of chemical expendables. Research sponsored by NASA Johnson Space Center is currently being pursued at Texas A&amp;M University to demonstrate the feasibility of the concept for oxidation of organic impurities ...

Electrocatalysts for electrooxidation of methyl formate

Applied Catalysis A: General, 2011
Abstract Carbon-supported PtSn, PtPd, and PtRuPd catalysts are prepared by chemical reduction with hydrothermal treatment, and their electrochemical properties for methyl formate electrooxidation are investigated by cyclic voltammetry, chronoamperometry, and CO stripping voltammetry in comparison with commercial Pt/C and PtRu/C catalysts.

Electrooxidation of dyestuffs in waste waters

Journal of Chemical Technology & Biotechnology, 1995
AbstractAn electrochemical oxidation cell is used to reduce the concentrations of organic dyes and chemical oxygen demand in an aqueous effluent. The importance of the presence of an electrolyte is recorded and the effects of changing both electrolyte concentration and initial dye concentration are reported.

Electrooxidative 1,3-Oxo/Carboamination of Arylcyclopropanes

The Journal of Organic Chemistry
Herein, the work demonstrates an electrochemically paired electrolysis approach facilitating the efficient achievement of the electrooxidative 1,3-oxo/carboamination of arylcyclopropanes under mild conditions. The formation of 1,3-arylamination of arylcyclopropanes involves commercially available amine redox mediators through a radical-radical process.

Electrooxidative Thiocyanation of Hydroxy‐ and Alkoxybenzenes

European Journal of Organic Chemistry
AbstractWe developed an original method for thiocyanation of hydroxy‐ and alkoxy‐substituted benzenes (including naturally occurring compounds) using electrogenerated thiocyanogen, (SCN)₂. The presence of zinc chloride as a Lewis acid significantly enhances reaction efficiency by activating thiocyanogen.

Electrooxidative thiocyanation and halogenation of azopyrazoles

Mendeleev Communications
The anodic C-H functionalization of azopyrazoles [3,3'-(diazenediyl)dipyrazoles] with thiocyanate, bromide, and chloride anions, with or without ZnCl₂ as a catalyst, affords the corresponding 4-thiocyanato or 4,4'-dihalo derivatives.

Electrooxidation of olefins at a silver electrode

Journal of Catalysis, 1975
Abstract The anodic oxidation of ethylene and propylene was carried out at a silver electrode under constant current conditions (galvanostatic) with the olefin and/or oxygen dissolved in the alkaline electrolyte at 23 ± 2′C. At current densities in the range of 10−5 to 10−9 A/cm2, the anodic oxidation of silver was accelerated in the presence of ...

Electrooxidation as a Route to Dihydrogen Complexes

1993
Efforts have been made to measure the oxidation potential of the formally 16 valence electron dihydride IrH2(PtBu2Ph)2Cl (1) by cyclic voltammetry. At a scan rate of 20 V/s the peak potential for the oxidation of 1 (1 mM / 0.1 M N(C4H9)4PF6) was found to be +0.70 V vs. the ferrocene/ferrocenium couple in dichloromethane at a platinum electrode (d = 1.0
