CO₂ Conversion to Alcohols over Cu/ZnO Catalysts: Prospective Synergies between Electrocatalytic and Thermocatalytic Routes.

ABSTRACT: The development of efficient catalysts is one of the main challenges in CO₂ conversion to valuable chemicals and fuels. Herein, inspired by the knowledge of the thermocatalytic (TC) processes, Cu/ZnO and bare Cu catalysts enriched with Cu⁺¹ were studied to convert CO₂ via the electrocatalytic (EC) pathway. Integrating Cu with ZnO (a CO-generation catalyst) is a strategy explored in the EC CO₂ reduction to reduce the kinetic barrier and enhance C-C coupling to obtain C₂₊ chemicals and energy carriers. Herein, ethanol was produced with the Cu/ZnO catalyst, reaching a productivity of about 5.27 mmol·g_cat^-1·h^-1 in a liquid-phase configuration at ambient conditions. In contrast, bare copper preferentially pr
