Electrooxidation of 2-propanol at Sputtered Pt Based Metal Electrodes

Ethanol Electrooxidation using Ti/(RuO2)(x) Pt(1-x) Electrodes Prepared by the Polymeric Precursor Method

Este trabalho descreve um estudo detalhado da oxidação eletroquímica de etanol sobre eletrodos de Ti/(RuO2)(x)Pt(1-x) com várias composições, preparados pelo método de precursores poliméricos. Os resultados obtidos usando voltametria cíclica e cronoamperometria mostraram que a melhor composição dos eletrodos de Ti/(RuO2)(x)Pt(1-x) para os processos de oxidação do CO e do etanol é Ti/(RuO2)(0.5)...

CO2 reduction at transition metal electrodes

A detailed understanding of the mechanism of electrochemical reduction of CO2 to form hydrocarbons can help design improved catalysts for this important reaction. Density functional theory calculations were used here to model the various elementary steps in this reaction on transition metal surfaces, in particular Cu(111) and Pt(111). The minimum energy paths for sequential protonation by eithe...

Nanocatalysts Impregnated Polythiophene Electrodes for the Electrooxidation of Formic Acid

Conductive and porous polythiophene (PTh) films, which are used as host matrices for Pt and Pt/Pd nanoparticles, are synthesized electrochemically. PTh films containing nanometre-sized Pt and Pt/Pd bimetallic particles are electro synthesized on an indium tin oxide (ITO) glass plate by voltammetric cycling between –0.1 to +1V (Vs Ag/AgCl / 2M NaCl). The ensuing PTh electrode, modified with nano...

High Performance Plasma Sputtered Fuel Cell Electrodes with Ultra Low catalytic metal Loadings

Electrooxidation of catecholamines at carbon nanotube-modified indium tin oxide electrodes.

In this study, we prepared carbon nanotube (CNT)/Nafion-modified ITO electrodes and investigated their electrochemical behavior. The CNTs were dissolved in a solution of the ionic polymer Nafion and then CNT/Nafion composite films were deposited onto ITO electrodes through spin-coating of this homogeneous solution. We studied the effects of chemical pretreatment of the CNTs and the pH of the bu...
