(a) MD simulations of CO2 adsorption in PE. The two‐dimensional snapshot of the simulation box represents the stages after running for 0 ns and 50 ns. Si: brown, O: red (in zeolite) and yellow (in CO2), C: green, and the bulk water phase is shown in a semi‐transparent blue volume. (b) The total CO2 molecule number in the entire system, and the CO2 molecule number in H2O and zeolite‐NC phase. (c) CO2 and H2O molecule number in bulk liquid, bulk gas, and zeolite‐NC region. (d) The interaction energy between zeolite‐NC and CO2 (zeolite‐CO2), zeolite‐NC and H2O (zeolite‐H2O), H2O and CO2 (H2O‐CO2). Error bars correspond to the Standard Deviation of three independent statistics. (e) CO2 adsorption isotherm of PE and corresponding non‐linear fitting. (f) Segmental fitting results for CO2 adsorption isotherm of PE based on intra‐particle diffusion model. Qt is the amount of adsorbed CO2 at a specific time. (g) Schematic illustration for CO2 diffusion in liquid‐film (I) and intra‐particle (II). (h) Schematic of the different regions within zeolite‐NC, and (i) their corresponding CO2 molecule number.

Electrosynthesis of high‐purity carbon monoxide (CO) from captured carbon dioxide (CO2) remains energy‐intensive due to the unavoidable CO2 regeneration and post‐purification stages. Here, we propose a direct high‐purity CO electrosynthesis strategy employing an innovative electrolyte, termed porous electrolyte (PE), based on “porous water”. Zeolit...
