Cascade Electrocatalytic Conversion of CO₂ to C₃ Products at Elevated Pressures.

ABSTRACT: Recent progress in the electrochemical reduction of CO₂ (CO₂RR) has led to notable breakthroughs in generating C₂ compounds such as ethylene and ethanol. Nevertheless, the direct formation of C₃ products encounters significant limitations due to the C₂-C₁ coupling reaction, posing a considerable challenge to improving their faradaic efficiency. Here, a design for an elevated pressure cascade catalytic reactor to convert CO₂ to C₃ products in a two-step electrochemical process is presented. At 25 bar pressure, by regulating the potential of the cascade system and the electrolyte flow rate, a 40% selectivity for 2-propanol on a copper electrode placed upstream of a silver electrode that converts CO_2<
