Fig. 3: Construction of localized mass transport channels for dilute CO2 electrolysis.
From: Localized mass transport channels for electro-upgrade of dilute CO2 toward high-yield C2+ products
a Schematic diagram of the specialized roles for In1@Cu2O and TfCOF to promote reaction kinetics and regulate mass transport, respectively. Inset in the middle revealing the steric effect for CO2 by calculating CO2 adsorption distribution. b FEs of different products for Cu2O and TfCOF-In1@Cu2O with dilute 80% CO2 inlets. The cell voltage of Ecell is reported without iR correction. The error bars represent the standard deviation from the measurement of three independent electrodes. c FFs toward total carbon products (FECtot) and d C2+ products (FEC2+) for TfCOF-In1@Cu2O in a flow cell with different concentrations of CO2 inlets. The simulated flue gas is 15% CO2 and 85% N2. e Calculated 2D distributions of CO concentration around electrodes with and without TfCOF layer with Multiphysics simulations. f Calculated coverages of adsorbed *CO and CO2 on the catalytic surface. The error bars represent the standard deviation from the measurement of three independent electrodes. Source data are provided as a Source Data file.
