Electrosynthesized Reduced Graphene Oxide-Supported Platinum, Platinum-Copper and Platinum-Nickel Nanoparticles on Carbon-Ceramic Electrode for Electrocatalytic Oxidation of Ethanol in Acidic Media

In this work, the electrocatalytic oxidation of ethanol was studied in acidic media at the wholly electrosynthesized nanocomposites: platinum and its alloys (copper and nickel) anoparticles/reduced graphene oxide on the carbon-ceramic electrode (Pt/rGO/CCE, Pt-Cu/rGO/CCE, and Pt-Ni/rGO/CCE electrocatalysts). The electrosynthesized nanocomposites were characterized by scan...

Local reaction kinetics by imaging: CO oxidation on polycrystalline platinum.

N O T E S Electrocatalytic Oxidation of Ethanol on Platinum Nanoparticles Modified Polyaniline Electrode

−− 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 role of adsorbed hydroxyl species in the electrocatalytic carbon monoxide oxidation reaction on platinum.

The assumption that "OH(ads)" or other oxygen containing species is formed on polycrystalline or nanoparticulate platinum through a fast and reversible process at relatively low potentials is often made. In this paper we discuss the implications of this assumption and the difficulty in reconciling it with experimental phenomena. We show how presenting chrono-amperometric transients as log-log p...

The investigation of pyrocatechol electrochemical mechanism in presence of nitrite ion on platinum electrode

In this study, the electrochemical mechanism of catechol in presence and absence of nitrite ion, is investigated in phosphate buffer medium (pH=7) using platinum electrode through cyclic voltammetry method in various scan rates. Electrochemical oxidation of catechol showed how quinone has changed to o-benzoquinone and also how o-benzoquinone has reacted with nitrite ion and potential scan rate ...
