Tema(s): Recursos en línea: Resumen: In this study, we investigate highly efficient sonogel carbon electrode (SGC/TiO2)modified with nanostructured titanium dioxide synthesized via sol-gel method employing surfactant template for tailor-designing the structural properties of TiO2. The stable SGC/TiO2 electrode detects catechol, a neurotransmitter, in the presence of ascorbic acid, a common interferent, using cyclic voltammetry. A possible rationale for the stable catechol detection of SGC/TiO2 electrode is attributed to most likely the adsorption of catechol onto highly porous TiO2 (surface area of 147m2 g-1 and porosity of 46.2
