Resumen
This proposal aims the rational design, preparation and characterization of colloidal Cu2O nanoparticles-based
electrocatalysts, and the evaluation of the performance of these materials for electrochemical CO2 conversion. These
materials will be prepared using hydrophobic coatings in order to avoid HER. Moreover, we aim to introduce defects in the
Cu2O nanoparticles by means of heteroatoms doping (Zn or Sn) in order to increase the concentration of adsorbed
intermediates that could increase the FE towards C2+. Finally, we will study in detail the materials stability upon long-term
real operation conditions in an electrochemical flow cell. We will analyse the change in FE towards C2+ products along time,
and its relationship with the electrocatalyst physico-chemical properties.
