Forming emulsions of carbon dioxide (CO 2 ) and water can largely expand the utility of CO 2 . Herein we propose for the first time the utilization of a metal–organic framework (MOF) for emulsifying CO 2 and water. Owing to the hybrid composition, MOF particles can easily assemble at the CO 2 /water interface to create a rigid protective barrier around the dispersed droplet. The MOF‐stabilized CO 2 and water emulsion has exceptional stability compared to those emulsions stabilized by surfactants or other solids. Moreover, the CO 2 and water emulsion stabilized by MOF is “tunable” due to the designable features of MOFs and adjustable character of CO 2 . Such a novel kind of emulsion composed of CO 2 , water, and MOF provides a facile route for constructing MOF superstructures with many advantages. The macroporous networks and hollow capsules of different kinds of MOFs have been successfully derived from CO 2 and water emulsions.
