A potentiostatic and atomic force Microscopy study of the nucleation and growth mechanisms of certain metallic cyanometalates
(AMER CHEMICAL SOC, 2007)
Nucleation and growth mechanisms (NGMs) of nickel(II) hexacyanoferrate, nickel(II) octacyanomolibdate, and copper(II) octacyanomolibdate were performed by means of the potential step technique by oxidizing the respective ...
Influence of the Cation Nature of the Sulphate Salt on the Electrochemical Synthesis of Sulfate-Doped Polypyrrole
(2011)
In this work, polypyrrole films were electrosynthesized from aqueous media onto a graphite-epoxy resin composite electrode (GCE) using sulphate ions as dopant. Potentiostatic electrosynthesis studies were done using different ...
Electropolymerization and morphologic characterization of α-tetrathiophene
(2013)
In this research, poly(α-tetrathiophene), poly(α-TTP), was potentiostatic and potentiodynamically electrosynthesized on Pt and F-doped SnO2 electrodes. The solvent effect (CH2Cl2 and CH3CN) on the nucleation and growth ...
Current transients for the hydrogen evolution reaction at high overpotentials on silver electrodes in acid solutions: Experiments and modelling
(Pergamon-Elsevier Science Ltd, 2013-10)
The hydrogen evolution reaction has been investigated on Ag(1 0 0) by potentiostatic current transientsat high overpotentials (- > 0.7 V) in acidic solutions. The reaction proceeds via the Volmer-Heyrovskymechanism, ...
Estudo mecanístico de reações de estado sólido: o caso do sistema Pb/PbSO4/Na2SO4
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2012-11-21)
In this work, the growth and reduction of PbSO4 in Na2SO4 solution under transient conditions was characterized. A novel methodology for the working-electrode surface preparation before stabilization enhanced the voltametric ...
Nucleation and growth mechanism of polycarbazole deposited by electrochemistry
(SOC BRASILEIRA QUIMICA, 2007)
Polycarbazole (PCz) thin films have been deposited by electro-oxidation of carbazole in LiCIO, + anhydrous acetonitrile onto SnO2 coated glass substrates, by potentiostatic method and the nucleation and growth mechanism ...
