Fig. 2

A The alcohol FE distribution and crossover as functions of the cell temperature. The secondary axis depicts the ratio of alcohols collected on the cathode to the total amount of alcohols (alcohol crossover). Products marked with a C are from the cathode gas outlet, and those marked with an A are from the anolyte. B The alcohol concentration collected in the cold-trap at the cathode gas outlet relative to cell temperature. C The alcohol FE distribution and crossover as functions of the CO flow rate. D The alcohol concentration and carbon efficiency concerning the input CO flow rate. E Schematic illustrating reduced alcohol crossover with increasing inlet CO flow rate. Red = oxygen; black = carbon; grey = hydrogen; yellow = copper. Where error bars are shown, values are means, and error bars indicate s.d. (n = 3 replicates). The source data for the results is provided as a Source Data file.
