摘要： The present invention relates to a catalytic system that is able to produce different chemical products by direct electrochemical reduction of carbon dioxide by controlling easily tunable parameters, such as applied current/potential, pressure, temperature, electrolyte composition and nature of the cathode at temperatures from room temperature up to 100°C, and pressures from atmospheric pressure up to 100 bar. These chemical products are alcohols with one to ten carbon atoms, ketones up to four carbon atoms and syngas. The catalytic system comprises a catalytic cathode coupled to a hydrophilic ionic liquid-based electrolyte containing water and dissolved C0 2. Preferably the invention envisages the use of carbon dioxide captured from industrial emissions and the use of electricity from renewable resources.
