Morphology-controlled CuO nanoparticles for electroreduction of CO2 to ethanol†
CuO nanoparticles with five morphologies were synthesized in large quantities using a simple method. They were in situ reduced to metallic Cu for the electroreduction of CO2. Alcohols with excellent selectivity for ethanol were obtained. The specific morphology was demonstrated to be more electrocatalytically active than others by multiple methods.
