Metal‐Organic Framework MIL‐68(In)‐NH2 on the Membrane Test Bench for Dye Removal and Carbon Capture

The metal‐organic framework (MOF) MIL‐68(In)‐NH2 was tested for dye removal from wastewater and carbon capture gas separation. MIL‐68(In)‐NH2 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)‐NH2 membranes were employed for dye removal in cross‐flow geometry, demonstrating strong molecular sieving. MIL‐68(In)‐NH2 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 H2/CO2 and CO2/CH4 separation. Neat metal‐organic framework (MOF) membranes and polyethersulfone (PES) mixed‐matrix membranes (MMMs) using MIL‐68(In)‐NH2, a giant pore Kagomé topology MOF, have been thoroughly investigated on the membrane test bench on their performance on wastewater dye removal and carbon capture gas separation.
