Abstract
Authors present a novel CO2–ionic liquid (IL) interfacial templating route for the production of hollow MOF microparticles. By adding the gaseous CO2 into IL phase under stirring, a large number of CO2 bubbles are generated. These provide numerous CO2–IL interfaces, forming the nucleation or agglomeration centers for the MOF nanocrystals.
This strategy was used to create the hollow and mesoporous Zn–BTC  tetrahedroids. The morphologies of the Zn–BTC polyhedra can be controlled by CO2 pressure. The Zn–BTC hollow microparticles have shown potential applications in gas separation and catalysis.
