Abstract
Abstract The metal‐organic framework (MOF) MIL‐68(In)‐NH 2 was tested for dye removal from wastewater and carbon capture gas separation. MIL‐68(In)‐NH 2 was synthesized as a neat, supported MOF thin film membrane and as spherical particles using pyridine as a modulator to shape the morphology. The neat MIL‐68(In)‐NH 2 membranes were employed for dye removal in cross‐flow geometry, demonstrating strong molecular sieving. MIL‐68(In)‐NH 2 particles were used for electrospinning of poylethersulfone mixed‐matrix membranes, applied in dead‐end filtration with unprecedented adsorption values. Additionally, the neat MOF membranes were used for H 2 /CO 2 and CO 2 /CH 4 separation.
