• Resumen

  • This thesis presents efficient approaches for producing high value compounds using CO2 as a building block. The methodology employed is based on electrochemical techniques, which enable eco-friendly chemistry solutions to be used, as well as maintaining the aim of offering a potential long-term strategy for reducing CO2 emissions in the atmosphere, while obtaining useful compounds. Moreover, the ionic liquids are introduced as a greener alternative to the traditional organic aprotic solvents employed in electrochemical experiments. Also, presenting a sustainable one-pot synthesis of an ionic liquid, using an ion exchange strategy.

    The electrochemical approach is relaying on three different strategies to valorize CO2; firstly, the direct reduction of CO2 on the electrode surface in presence of an imidazolium-based ionic liquid. The second one is based on the electrochemical activation through different C-X cleavages in the presence of CO2 saturated solutions, producing electrocarboxylation processes. Third one is based on a catalytic process through a homogeneous catalysis, where CO2 is indirectly reduced in the solution.
