In Figure we see that the computational model reproduces the characteristic features found in the experiment of CO2 adsorption for negative charging, desorption for positive charging and a combination with improved performance for the switching protocol. In order to quantitatively compare the CO2 pressure and concentration results of experiments and simulation respectively, we introduce 𝛿𝜌 . This is a dimensionless CO2 concentration inside the gas chamber that measures the relative change of CO2, but also incorporates the volume ratio of the gas chamber compared to the volume of the electrolyte and the voltage ratio of the voltages in the experiments and model (full details in Methods). The differences in applied voltages are due to the model becoming unstable at the higher voltages used in the experiments. We find that experiment display a total maximal change 𝛿𝜌 of 0.25, 0.29, and 0.62 for negative charging, positive charging and switching respectively, whereas the computational model predicts a maximal 𝛿𝜌 of 0.065, 0.10, and 0.15 respectively. Precise comparisons are not fully warranted due to the coarse nature of the model, but that the results are well within an order of magnitude does support that the method we propose in this work is at least partially responsible for the observed carbon capture features exhibited by the device.
