Abstract
Metal organic framework (MOF) has been recognized as a unique molecular sieving material with flexible framework, enabling interesting “gate-opening” functionality. Recently, it is recognized that such structural transition is induced by molecular adsorption and controlling the crystal size and shape is an effective factor for regulating the structural flexibilities and mass transport properties. This review discusses recent progress in MOF membranes and the challenges and opportunities for future membrane separation technology, and provides an overview of seedingfree aqueous synthesis of crystal–size–engineered ZIF–8 MOF membranes.
