Resumen

The electrochemical reduction of nitrate ions was carried out on Pt-based nanoparticles supported on carbon Vulcan and deposited on a glassy carbon electrode. Different materials were evaluated: synthesized Pt₁₀/C, Pt-Sn_y/C (y = 10, 20 wt.%) and commercial Pt_x/C-ETEK (x = 10, 20 and 40 wt.%). Cyclic voltammetry technique was used for this purpose. It was found that the catalytic activity for hydrogen evolution reaction (HER) and nitrate electro-reduction (NER) follows the order Pt₁₀/C > Pt ₄₀/C-ETEK > Pt-Sn₂₀/C > Pt₂₀/C-ETEK > Pt-Sn₁₀/C > Pt₁₀/C-ETEK. The electrochemically active surface area (ECSA), charge due to nitrate electro-reduction (QN_O3-), and kinetic parameters were calculated in order to understand the catalytic behavior.
