Cáceres, César; Martínez, Manuel; Rodríguez, Carlos; Dreyse, Paulina; Ortega, Victoria; Isaacs, Mauricio (Elsevier B.V., 2014)The preparation of an ITO (Indium Tin Oxide) modified electrode with a mixed valence CoIII/FeII complex is described. The ITO electrode was initially modified with Au nanoparticles by dip coating in order to obtain and ...

Dreyse, Paulina; Isaacs, Mauricio; Calfumán, Karla; Cáceres, César; Aliaga, Alvaro; Aguirre, María Jesús; Villagra, Diego (2011)This work describes the preparation of modified electrodes with Poly-tetraruthenated porphyrin. Also, a detailed Raman and electrochemical characterization of these surfaces is shown. Glassy carbon electrodes were modified ...
