Ureta Zañartu, María Soledad; Yáñez Soto, Claudia; Zagal Moya, José H. (SOCIEDAD CHILENA DE QUIMICA, 2001-03)The effect of ageing the electrode on the mass response was studied by two approaches, namely: i) ageing the Pt deposits on the Au/Q substrate and ii) ageing the Au/Q substrate and then examining the response of the Pt ...

Ureta Zañartu, María Soledad; Bravo, P.; Reyes Cava, Gloria Ximena; Yañez, Claudia; Gancedo, José Ramón; Gutiérrez, C.; Marco, José F. (SOCIEDAD CHILENA DE QUIMICA, 2001-09)The electro-oxidation of methanol at Pt-Ir and Pt deposits, and at Pt, Ir, and Pt-Ir wires in sulfuric acid solution was studied by cyclic voltammetry (CV), and in the case of Pt-Ir and Pt electrodeposits, also with the ...

Ureta Zañartu, María Soledad; Yáñez Soto, Claudia; Gutiérrez, C. (ELSEVIER SCIENCE SA, 2004-08-01)The system of I-octanol-beta-cyclodextrin in 0.5 M HClO4 at Pt electrodeposited on an Au/quartz crystal (Pt/Au/Q) has been studied by cyclic voltammetry (CV), the electrochemical quartz crystal microbalance (EQCM) and ...

Ureta Zañartu, María Soledad; Yáñez Soto, Claudia; Páez, Maritza; Reyes Cava, Gloria Ximena (ELSEVIER SCIENCE SA LAUSANNE, 1996-04-12)The activity of Pt, Pt + Pb and Pt + Ir deposits on Ti, for ethylene glycol (EG) oxidation, was studied in both 0.5 M H2SO4 and 0.5 M NaOH solutions. The metallic deposits were prepared by electrolysis at constant current ...

Ureta Zañartu, María Soledad; Yáñez Soto, Claudia; Reyes Cava, Gloria Ximena; Gancedo, José Ramón; Marco, José F. (SPRINGER VERLAG, 1998-05)The activity of Pt-Ir deposits on titanium for the reduction of the nitrate ion in 0.5 M perchloric acid was studied. The electrodes were characterized by SEM-EDAX, XPS and cyclic voltammetry. The activity of the electrodes ...

Ureta Zañartu, María Soledad; Yáñez Soto, Claudia (PERGAMON-ELSEVIER SCIENCE LTD, 1997)The electro-reduction of nitrate ions in acid medium on Pt, Ir and on a 70:30 Pt, Ir alloy was studied by cyclic voltammetry. The alloy has a higher activity than the pure metals, which was interpreted as being due to ...
