Abstract
AbstractThe electrocarboxylation reaction is an attractive means to convert CO2 into valuable chemicals under ambient conditions, while it still suffers from low efficiency due to the high stability of CO2. In this work, we report a double activation strategy for simultaneously activating CO2 and acetophenone by silver-doped CeO2 (Ag-CeO2) nanowires, featuring as an effective electrocatalyst for electrocarboxylation of acetophenone with CO2. Compared to the Ag foil, Ag nanoparticles and CeO2 nanowires, the Ag-CeO2 nanowire catalyst allowed to reduce the onset potential difference between CO2 and acetophenone activation, thus enabling efficient electrocarboxylation to form 2-phenyllactic acid. The Faradaic efficiency for producing 2-phenyllactic acid reached 91% at −1.8 V versus Ag/AgI. This double activation strategy of activating both CO2 and organic substrate molecules can benefit the catalyst design to improve activities and selectivities in upgrading CO2 fixation for higher-value electrocarboxylation.
