Extended Data Fig. 6: The distribution of CO2 in CO/CO2 co-feeds.
From: Coverage-driven selectivity switch from ethylene to acetate in high-rate CO2/CO electrolysis
CO2 distribution over CuO nanosheet catalyst measured in 0.1 M KOH under CO/CO2 (3:1) co-feed. CO2, CO32–, HCO3– in anode outlet solution were adsorbed and quantified by saturated Ba(OH)2 solution. CO2 in cathode outlet was quantified by on line GC. Most of CO2 is transferred to anode through carbonate crossover.
