Cu(ii)-nanoparticle-derived structures under CO

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.
