Resumo: This paper addresses the hydrogen evolution reaction (HER) occurring on platinum in an aqueous solution containing dissolved CO2 at several pressures. A new setup that uses a low inertia rotating disk electrode (RDE) adapted in an autoclave is proposed. This setup allows obtaining polarizations curves and electro-hydrodynamic (EHD) impedance, the latter for the first time in pressured conditions. New equations to adjust the Levich plots are proposed and briefly discussed.
