Catalytic oxidation of nitric oxide and nitrite mediated by water-soluble high-valent iron porphyrins at an ITO electrode
A stepwise catalytic oxidation for nitric oxide and nitrite by water-soluble iron(III) meso-tetrakis(N -methylpyridinium-4yl)porphyrin (Fe(4-TMPyP)) was first revealed by using an ITO electrode. Electrochemical and spectroelectrochemical studies characterized the formation of oxoiron(IV) porphyrin and oxoiron(IV) porphyrin p-cation radical in the oxidation of Fe(4TMPyP). O@Fe(4-TMPyP) showed se...
متن کاملCatalysis of water oxidation in acetonitrile by iridium oxide nanoparticles.
Water oxidation catalysed by iridium oxide nanoparticles (IrO2 NPs) in water-acetonitrile mixtures using [RuIII(bpy)3]3+ as oxidant was studied as a function of the water content, the acidity of the reaction media and the catalyst concentration. It was observed that under acidic conditions (HClO4) and at high water contents (80% (v/v)) the reaction is slow, but its rate increases as the water c...
متن کاملElectrolytic Model System for Reductive Dehalogenation in Aqueous Environments
Tetrachloromethane (CT) is transformed in biological systems via two major pathways: hydrogenolysis to trichloromethane (CF) and hydrolysis to carbon dioxide. The mechanism of hydrolysis is poorly understood. One possibility is a hydrolytic reduction of CT to formate or carbon monoxide followed by oxidation to carbon dioxide. In biological systems, formate and carbon monoxide are readily oxidiz...
متن کاملHigh-Potential Electrocatalytic O2 Reduction with Nitroxyl/NO x Mediators: Implications for Fuel Cells and Aerobic Oxidation Catalysis.
Efficient reduction of O2 to water is a central challenge in energy conversion and many aerobic oxidation reactions. Here, we show that the electrochemical oxygen reduction reaction (ORR) can be achieved at high potentials by using soluble organic nitroxyl and nitrogen oxide (NO x ) mediators. When used alone, neither organic nitroxyls, such as 2,2,6,6-tetramethyl-1-piperidinyl-N-oxyl (TEMPO), ...
متن کاملStudying the Electrochemical Behavior of 2-amino-4-methylphenol in the Presence of Penicillin Amine Using Cyclic Voltammetry Technique
The studies performed about electrochemical oxidation 2-amino-4-methylphenol indicate that ortho-quinone yielded through oxidation of this chemical compound was unstable and it could be used as Michael acceptor under solvent influences, carrier electrolyte, additives and could be transformed into the various compounds in the form of 1-4 addition Michael reaction. Based on this, in the paper fir...
