Cu(ii)-nanoparticle-derived structures under CO2 reduction conditions: a matter of shape

Abstract

Uncovering the nature and formation mechanisms of active sites in electrocatalysts is crucial for advancing energy conversion technologies. Cu(II)-derived electrodes show unique activity in CO₂ electroreduction, but its origins are not fully understood. We investigate the structural evolution of Cu(OH)₂ nanoparticle-derived electrodes and its effect on their performance in CO₂ electroreduction.
