Fig. 4: Continuous upgrade of dilute CO2 by TfCOF-In1@Cu2O in the flow cell.
From: Localized mass transport channels for electro-upgrade of dilute CO2 toward high-yield C2+ products
a Total current densities (J) of TfCOF-In1@Cu2O with different CO2 concentrations. b Partial current densities toward C2+ products under different potentials and CO2 concentrations. c Yield of CO, CH4, C2H5OH, and C2H4 with the inlet of 80% CO2. The yield for C2H6 is not shown in the figures due to the low selectivity (FE < 3%). d Total current density and partial current density for C2+ and C1 products with different adding amounts of TfCOF. e Stability measurements of TfCOF-In1@Cu2O at Ecell of 3.4 V with inlet of 80% CO2. f Photograph of the electrolyzer stack. g Total current (JTtot) and partial current for C2+ (JTC2+) and C1 (JTC1) products with stack potentials in the electrolyzer stack with inlet of 80% and 100% CO2. The error bars represent the standard deviation from the measurement of three independent electrodes. Source data are provided as a Source Data file.
