Abstract

We report a template-free and easy solvent evaporation method during carbonizing a metal-organic framework (MOF) for the construction of large-scale meso- and macropore. While the direct thermal evaporation method of non-volatile solvent captured in micropore of a MOF is believed to reduce overall porosity of the resultant MOF, this method unprecedentedly directs the reorganization of MOFs toward the production of ultrahigh porous carbon materials. The obtained porous carbon materials possess a unique interconnected three-dimensional wormhole-like structure, high specific surface area (3000 m² g ^-1), and exceptionally high pore volume (5.45 cm³ g ^-1). The micropores, along with accessible meso- and macropores, provide ion storage site and ion transport channel, respectively, that contributes to a rapid elimination of large amounts of salt within a very short period of time.
