The electroreflectance (ER) technique has been applied to the study of a Pt(111) electrode in different acidic and alkaline electrolytes. The variation in the normalised potential derivative of the reflectance signal, 1/R(dR/dE) is observed in sulphuric and perchloric acid media…

Nanostructured cobalt oxide (Co3O4) electrodes were prepared by two different methods. The first one involved the synthesis of Co3O4 nanoparticles through a nanocasting route using commercial silica gel as a sacrificial template, and in the second one, the Co3O4 electrodes…

The electrochemical oxidation of the aniline dimers 2-aminodiphenylamine (2-adpa) and 4-aminodiphenylamine (4-adpa) has been
performed in strongly acidic medium on platinum, graphite, and indium tin oxide electrodes. The resulting films have been
characterized by a number of electrochemical, microscopic, and…

The redox process undergone by the electrochemically synthesized poly(2,2-dithiodianiline), poly(DTDA), has been examined in
acetonitrile-water mixtures by electrochemical and spectroscopic techniques. The spectroscopic properties of this material are equivalent to those exhibited by the chemically synthesized one. The polymeric structure…

Antimony-doped tin dioxide electrodes supported on titanium have been used in the electrochemical treatment of aqueous solution
containing phenol. Ti/SnO2–Sb anode has high efficiency in the elimination of phenol, but its use is hindered by its short service
life. The…

Aniline (ANI) and 2-aminoterephthalic acid (2ATA) copolymers, with different compositions, were prepared by
chemical oxidative polymerization varying the feed ratio. The new materials have been characterized by techniques such
as XPS, FTIR, Raman spectroscopies and thermal analysis. It has been…

The electrochemical regeneration of an activated carbon, previously saturated with toluene by gas phase adsorption, was studied. Cathodic and anodic regeneration methods were analyzed using a small batch electrochemical cell. In both cases, a stripping efficiency close to 100% was…

In contrast to what is observed in alkaline media, cyanide adlayers formed on Pt(100) are very reactive in 0.1 M HClO4 solutions. In this medium, dissimilar behaviour has been observed for the potential regions above and below 0.4 V (RHE).…

Different Pt-based electrocatalysts supported on carbon nanofibers and carbon black (Vulcan XC-72R) have been prepared using a polymermediated synthesis. The electrocatalysts have been characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and cyclic voltammetry. The effect of carbon nanofibers…

In this paper we present the study of the electrochemical properties of the following conducting polymers: poly(o-anisidine),
polyaniline and copolymers of aniline and o-anisidine obtained by a new synthetic method. The polymers are synthesized
in free-of-acid conditions, using an activated…
