Abstract Electrochemical CO 2 reduction reaction in aqueous electrolytes is a promising route to produce added-value chemicals and decrease carbon emissions. However, even Gas-Diffusion Electrode devices, low solubility limits catalysis rate selectivity. Here, we demonstrate that when assembled over heterogeneous electrocatalyst, film of nitrile-modified Metal-Organic Framework (MOF) acts as remarkable -solvation layer increases its local concentration by ~27-fold compared bulk electrolyte, reaching 0.82 M. When mounted on Bi catalyst Gas Diffusion Electrode, the MOF drastically improves -to-HCOOH conversion, above 90% selectivity partial HCOOH currents 166 mA/cm (at −0.9 V vs RHE). The also facilitates through stabilization intermediates, identified operando infrared spectroscopy Density Functional Theory. Hence, presented strategy provides new molecular means enhance electrochemical reaction, leading it closer requirements for practical implementation.
