Abstract

Composites of PANi and TiO2 nanoparticles were investigated for applications in direct methanol fuel cell and alcohol sensors. Anilinium sulfate and TiO2 with nanometric size were electropolymerized in 0.5M H2SO4 solution on carbon paper. Oxidation and response to methanol was measured by chrono amperometry and elctrochemical impedance spectroscopy..
