The Effect of Pressure on ZIF‐8: Increasing Pore Size with Pressure and the Formation of a High‐Pressure Phase at 1.47 GPa

Abstract

The big squeeze: On applying pressure to ZIF-8 (0.18 GPa), solvent can be squeezed into the porous cavities, initially increasing the pore size and unit-cell volume. On increasing pressure further to 1.47 GPa, a phase transition takes place (see picture). This transition allows more solvent to enter the original nanopores and enlarges the narrow channels connecting these pores, resulting in higher porous volume and solvent content.
