Conclusion
Conversion of CO2 into hydrocarbons via continuous flow electroreduction

During this work, we studied the electroreduction reaction of CO₂ to hydrocarbons. The system presented is the first example of gas-phase carbon dioxide reduction, in fixed-bed mode, at room temperature and ordinary pressure. The reaction was carried out in two types of reactor: firstly with a continuous flow of CO₂ and H₂ . In this case, the protons required for the CO₂ reduction reaction are supplied by the oxidation of H₂ to H⁺. However, the conversion obtained was extremely low, i.e. less than 1% after one hour of reaction. The nature of the products formed is mainly hydrocarbons (from C₁ to C₇) and also a small amount of ethanol.

To study the electroreduction reaction of CO₂ more closely, we therefore decided to change the reaction mode from a continuous mode, i.e. with a continuous flow...
