A conducting nanocomposite via intercalative polymerisation of 2-metylaniline with aniline in montmorillonite cation-exchanged

Chouli, Faiza; Benyoucef, Abdelghani; Yahiaoui, A.; Quijada Tomás, Cesar; Morallón, E. (Springer Verlag (Germany), 2012-11)

Polymer/montmorillonite nanocomposites were prepared. Intercalation of 2-methylaniline with aniline monomers into montmorillonite modified by cation was followed by subsequent oxidative polymerization of the monomers in ...
Algerian natural montmorillonites for arsenic(III) removal in aqueous solution

Zehhaf, A.; Benyoucef, A.; Quijada Tomás, Cesar; Taleb, S.; Morallón, E. (Springer Verlag (Germany), 2015-02)

The adsorption of As(III) from aqueous solutions using naturally occurring and modified Algerian montmorillonites has been investigated as a function of contact time, pH, and temperature. Kinetic studies reveal that uptake ...
Effect of the intercalated cation-exchanged on the properties of nanocomposites prepared by 2-aminobenzene sulfonic acid with aniline and montmorillonite

Toumi, I.; Benyoucef, A.; Yahiaoui, A.; Quijada Tomás, Cesar; Morallón, E. (Elsevier, 2013-02-25)

[EN] Polymer/montmorillonite nanocomposites were prepared. Intercalation of 2-aminobenzene sulfonic acid with aniline monomers into montmorillonite modified by cation was followed by subsequent oxidative polymerization of ...
Electro-oxidation of cyanide on active and non-active anodes: Designing the electrocatalytic response of cobalt spinels

Berenguer, R.; Quijada, César; La Rosa-Toro, A.; Morallón, E. (Elsevier, 2019-01-08)

[EN] The feasibility of the electrochemical technologies for wastewater treatment greatly relies on the design of efficient but inexpensive electrocatalysts. It is generally accepted that the so-called ¿non-active¿ anodes ...
Electrochemical and In Situ FTIR Study of o-Cresol on Platinum Electrode in Acid Medium

Taleb, Z.; Montilla, F.; Quijada Tomás, Cesar; Morallón, E.; Taleb, S. (Springer Verlag (Germany), 2014-04)

The electrochemical behaviour of o-cresol in acidic medium on platinum electrode has been studied by cyclic voltammetry and in situ Fourier transform infrared spectroscopy. The o-cresol suffers hydrolysis during oxidation ...
Electrochemical behaviour of PSS-Functionalized silica films prepared by electroassisted deposition of Sol-Gel precursors

Gamero-Quijano, A.; Huerta, Francisco; Salinas-Torres, David; Morallón, E.; Montilla, Francisco (Springer Verlag (Germany), 2015-01)

Porous, electrically insulating SiO2 layers containing polystyrene sulfonate (PSS) were deposited on glassy carbon electrodes by an electrochemically assisted deposition method. The obtained material was characterized by ...
Kinetic and thermodynamic study of the adsorption of As(III) from aqueous solutions by naturally occurring and modified montmorillonites

Zehhaf, A.; Benyouncef, Abdelghani; Quijada Tomás, Cesar; Taleb, Safia; Morallón, E. (Comporter SRL, 2012-06-15)

[EN] Adsorption of As(III) from aqueous solutions using naturally occurring and modified Algerian montmorillonites was investigated as a function of contact time, pH and temperature. Kinetic studies reveal that uptake of ...
Manganese oxides/LaMnO3 perovskite materials and their application in the oxygen reduction reaction

Flores-Lasluisa, Jhony X.; Huerta, Francisco; Cazorla-Amorós, D.; Morallón, E. (Elsevier, 2022-05-15)

[EN] Manganese-based materials can catalyze the oxygen reduction reaction (ORR), although their activity is known to depend on the crystalline phases and on the concentration of surface-active species. In the present study, ...
Modulation of the silica sol-gel composition for the promotion of direct electron transfer to encapsulated cytochrome

Gamero-Quijano, A.; Huerta, Francisco; Morallón, E.; Montilla, Francisco (American Chemical Society, 2014-09-02)

The direct electron transfer between indium-tin oxide electrodes (ITO) and cytochrome c encapsulated in different sol-gel silica networks was studied. Cyt c@silica modified electrodes were synthesized by a two-step ...
Revisiting the redox transitions of Polyaniline. Semiquantitative interpretation of electrochemically induced IR bands

Huerta, Francisco; Quijada, César; Montilla, F.; Morallón, E. (Elsevier, 2021-09-15)

[EN] The redox transitions of PANI in acidic medium have been monitored by a combination of cyclic voltammetry, in situ conductance and in situ FTIR spectroscopy. The results of the semiquantitative analysis strongly suggest ...
Studies on the conducting nanocomposite prepared by polymerization of 2-aminobenzoic acid with aniline from aqueous solutions in montmorillonite

Belmokhtar, A.; Benyoucef, A.; Zehhaf, A.; Yahiaoui, A.; Quijada Tomás, Cesar; Morallón, E. (Elsevier, 2012-12)

A simple and facile method was used to synthesize poly(o-aminobenzoic acid) (PoABA) and polyaniline (PANI) nanocomposites with sodium montmorillonite (M-Na) using in situ intercalative oxidative homo-, and co-polymerization ...
