Electrochemical methods to enhance the capacitance in activated carbon/polyaniline composites
Bleda Martínez, María Jesús - Peng, Chuang - Zhang, Shenguen - Chen, George Z. - Morallón Núñez, Emilia - Cazorla Amorós, Diego

Formato:	info:eu-repo/semantics/article
Enlaces:	Activated carbon/polyaniline composites have been prepared using different electrochemical methods: single-step potentiostatic polymerization, multiple-step potentiostatic polymerization, and potentiodynamic polymerization with the anodic potential limits being fixed at either 0.75 or 1 V (vs Ag/AgCl). The prepared composite samples were characterized…

Study of the chemical copolymerization of 2-aminoterephthalic acid and aniline. Synthesis and copolymer properties
Arias Pardilla, Joaquín - Salavagione, Horacio Javier - Barbero, César Alfredo - Morallón Núñez, Emilia - Vázquez Picó, José Luis

Formato:	info:eu-repo/semantics/article
Enlaces:	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…

Application of recent double-hybrid density functionals to low-lying singlet-singlet excitation energies of large organic compounds
Di Meo, Florent - Trouillas, Patrick - Adamo, Carlo - Sancho García, Juan Carlos

Formato:	info:eu-repo/semantics/article
Enlaces:	The present work assesses some recently developed double-hybrid density functionals (B2π-PLYP, PBE0-DH, and PBE0-2) using linear-response Tamm-Dancoff Time-Dependent Density Functional Theory. This assessment is achieved against experimentally derived low-lying excitation energies of large organic dyes of recent interest, including some…

Pt/carbon nanofibers electrocatalysts for fuel cells: effect of the support oxidizing treatment
Zaragoza Martín, Francisco - Sopeña Escario, Daniel - Morallón Núñez, Emilia - Salinas Martínez de Lecea, Concepción

Formato:	info:eu-repo/semantics/article
Enlaces:	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…

Voltammetric and in situ FTIRS study on CN- and Au(CN)-x complexes at the polycrystalline gold surface in citrate medium
Huerta Arráez, Francisco - Mele, Claudio - Bozzini, Benedetto - Morallón Núñez, Emilia

Formato:	info:eu-repo/semantics/article
Enlaces:	The adsorption and reactivity of citrate anions, cyanide anions, and the Au(I) and Au(III) cyanocomplexes (KAu(CN)2 and KAu(CN)4, respectively) on gold polycrystalline electrodes have been investigated by means of cyclic voltammetry and in situ FTIR spectroscopy in pH 7 sodium…

Spectroelectrochemical study of the oxidation of aminophenols on platinum electrode in acid medium
Salavagione, Horacio Javier - Arias Pardilla, Joaquín - Garcés Terradillos, Pedro - Morallón Núñez, Emilia - Barbero, César Alfredo - Vázquez Picó, José Luis

Formato:	info:eu-repo/semantics/article
Enlaces:	The electrochemical oxidation of para-, meta- and ortho-aminophenols was carried out using a platinum electrode in aqueous acid medium. The spectroscopic results indicate that p-aminophenol suﬀers hydrolysis giving the formation of hydroquinone/p-benzoquinone. CO2 has been detected by in situ FTIR…

Conducting films obtained by electro-oxidation of p-aminodiphenylamine (ADPA) in the presence of aniline in buffer aqueous solution at pH 5
Cases Iborra, Francisco Javier - Huerta Arráez, Francisco - Lapuente Aragó, Rocío - Quijada Tomás, César - Morallón Núñez, Emilia - Vázquez Picó, José Luis

Formato:	info:eu-repo/semantics/article
Enlaces:	The electrochemical oxidation of aniline and p-aminodiphenylamine (ADPA) was carried out in a phosphate buffer solution at pH 5. Cyclic voltammetry and ‘‘in situ’’ FTIR spectroscopy were combined to study the redox behavior of the oxidation products. When ADPA is…

Voltammetric and in situ FTIRS study of the electrochemical oxidation of aniline from aqueous solutions buffered at pH 5
Cases Iborra, Francisco Javier - Huerta Arráez, Francisco - Garcés Terradillos, Pedro - Morallón Núñez, Emilia - Vázquez Picó, José Luis

Formato:	info:eu-repo/semantics/article
Enlaces:	The electrochemical oxidation of aniline at low concentration was carried out in phosphate buffer solutions of pH 5. Both electrochemical and spectroscopic results indicate that during the initial stages of aniline oxidation, a dimerisation process takes place. The dimer has…
