Design of nanostructured Cu oxides for the electrocatalytic CO₂ reduction

In the present study, Cu oxides-based materials, selected for their strong coordination ability with CO intermediates, were synthesized following different soft-chemistry approaches, varying the final morphology (i.e., size/shape, aspect ratio, crystal planes orientation). After performing morphological (SEM), and structural (XRD) characterizations, such materials were thus tested in the electrocatalytic CO₂ reduction (e-CO₂R), showing a different selectivity toward specific C1-C2+ products depending on the final morphology.
