摘要: Abstract The electrocatalytic reduction of CO 2 to alcohols was investigated in a co-electrolysis cell based on solid polymer electrolyte. PtRu/C and Ru/C catalysts were used gas diffusion cathodes for the humidified . An IrRuO x catalyst oxygen evolution from liquid water at anode. This electrochemical reactor employed perfluorosulfonic acid membrane electrolyte separator (Nafion ® ) it operated temperature range 30 °C 95 °C. cathode characterized by well-dispersed metal nanoparticles (2 nm mean particle size) carbon black support. Electrochemical polarization tests carried out presence or with inert comparison. results evidenced that direct reaction surface essentially occurring low voltages ( conversion.
