Abstract: Gas‐liquid reactions form the basis of our everyday lives, yet they still suffer poor reaction efficiency and are difficult to monitor in situ, especially at ambient conditions. Herein, we drive an inert gas‐liquid reaction between aniline and CO2 at 1 atm and 298 K by selectively concentrating these immiscible reactants at the interface between metal‐organic framework and solid nanoparticles (solid@MOF). Real‐time reaction SERS monitoring and simulation investigations affirm the formation of phenylcarbamic acid, which was previously undetectable because they are unstable for post‐reaction treatments. The solid@MOF ensemble gives rise to a >28‐fold improvement to reaction efficiency as compared to ZIF‐only and solid‐only platforms, emphasizing that the interfacial nanocavities in solid@MOF are the key to enhance gas‐liquid reaction. Our strategy can be integrated with other functional materials, hence opens up new opportunities for ambient‐operated gas‐liquid applications.
