Recently, increasingly attentions have been paid to the electro-oxidation of ethanol in alkaline media in the context of using ethanol as a fuel in anion-exchange membrane fuel cell. Alkaline media presents several advantages compared to acidic media. It has been found that the electrocatalytic activity for etanol oxidation in alkaline media is much higher than that in acidic media [1]. Further...

−− The electrocatalytic properties of platinum nanoparticles incorporated into polyaniline films was investigated for oxidation of ethanol in sulfuric acid solutions. The electropolymerization of aniline and the electrochemical depositions of platinum particles into the polyaniline film were achieved by cyclic voltammetry. The effect of the formation conditions of platinum-modified polyaniline ...

The present paper reports electrochemical and UV-VIS spectroscopic studies on the process of electrooxidation of quercetin 3,4'-di-O-β-glucopyranoside (Q 3,4'-diglc) molecule, at glassy carbon electrode surface in 0.1 M sodium acetate – acetic acid buffer in 90 % methanol solution. The process starts at 3'-OH group (ring B), followed by oxidation of 5,7-dihydroxyl group in ring A. As a result o...

The electrooxidation of methylhydrazine, 1,2-dirnethylhydrazine, and 1,1 -dimethylhydrazine at a platinum electrode was studied using chronopotentiometry, coulometry, and product analysis. The results show that methjJlhydrazine is oxidized in an over-all four-electron reaction to nitrogen and methanol. The oxidation of 1,2-dimethylhydvazine proceeds by an initial two-electron oxidation, followe...

The electrooxidation of a,c~'-coupled thiophene oligomers alkyl-protected toward anodic coupling at the terminal c~ positions was studied in solid state at room temperature. Reversible oxidation goes from a single one-electron step oxidation for the tetramers to two separate oneelectron steps for the pentamer and hexamer. The oxidation potentials are found to be primarily dependent on the conju...

In this paper, mesoporous electrodes consisting of Sb-doped SnO2 deposited onto Ti plates that had undergone controlled corrosion under acidic medium were synthesized via a spin-coating method and morpho-structurally characterized X-ray diffraction (XRD) scanning electron microscopy (SEM). The electrochemically tested to examine their degradation/mineralization through electrooxidation (EO) dox...

Fabricating highly efficient Pd-based nanocatalysts with a well-defined structure is desired for the commercialization of direct ethanol fuel cell (DEFC). Herein, series hierarchical three-dimensional N-doped hollow graphene spheres (NHGS) supported dendritic PdCu alloy catalysts Pd$_{x}$Cu$_{(d)}$-NHGS (x: Cu/Pd theoretical molar ratio 4, 2, and 1) are assembled by one-pot ascorbic acid reduct...
