The electrocatalytic oxidation of ferrocene (Fc) at neutral pH in aqueous solution has been studied over thin films of electroactive sulfonated polyaniline (SPAN) by cyclic voltammetry. Strong adsorption of the oxidised species (ferrocenium ion) on the polymer arises as the…

Electrodeposition of Pt nanoparticles under
potentiostatic conditions was performed on several types of carbon electrode supports: commercial macroporous carbon (a three-dimensional electrode), glassy carbon and
graphite. Conducting polymers (poly-aniline and poly-oaminophenol) were also used. The platinum nanoparticles were obtained by…

The electrochemical homopolymerization of o-aminobenzoic acid has been performed on both gold and graphite surfaces in perchloric acid aqueous medium by cyclic scanning of the potential. Electroactive polymeric materials are formed in all cases but the amount of electropolymerization products…

The templated growth of polyaniline through porous sol–gel films on ITO substrates has been performed. The polyaniline–silica composites have been synthesized by electrochemical reactive insertion in potentiodynamic and potentiostatic conditions. When the polymer is synthesized by potential step experiments, the…

Industrial wastewater with a high value of CDO (Chemical Demand of Oxygen e. g. - 100 000 mg.l-1) was treated by electrolysis. The pH, temperature and anode material of the electrolysis process have been optimized. It was shown that the…

The electrochemical reduction of perchloroethylene (PCE) in water has been analyzed through voltammetric studies with a
rotating disc electrode and controlled potential bulk electrolysis. The influence of the mass transport conditions and initial concentration on lead, copper and carbon 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…
