Molecularly soldered covalent organic frameworks for ultrafast precision sieving

Science Advances, Journal Year: 2021, Volume and Issue: 7(13)

Published: March 24, 2021

The weak interlamellar interaction of covalent organic framework (COF) nanocrystals inhibit the construction highly efficient ion/molecular sieving membranes owing to inferior contaminant selectivity induced by defects in stacked COF and stability issues. Here, a facile situ molecularly soldered strategy was developed fabricate defect-free ultrathin with precise abilities using typical chemical environment for condensation polymerization dopamine self-polymerization. experimental data density functional theory simulations proved that reactive oxygen species generated during catalyze nucleophilic reactions COF, thus facilitating counter-diffusion growth thin layers. Notably, can eliminate soldering crystals, fortifying mechanical properties membranes. exhibited ultrafast precision molecular separation ion removal both aqueous solvents, which surpasses state-of-the-art

Differentiating Solutes with Precise Nanofiltration for Next Generation Environmental Separations: A Review

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(3), P. 1359 - 1376

Published: Jan. 13, 2021

Selective removal or enrichment of targeted solutes including micropollutants, valuable elements, and mineral scalants from complex aqueous matrices is both challenging pivotal to the success water purification resource recovery unconventional resources. Membrane separation with precision at subnanometer even subangstrom scale paramount importance address those challenges via enabling "fit-for-purpose" wastewater treatment. So far, researchers have attempted develop novel membrane materials precise tailored selectivity by tuning structure chemistry. In this critical review, we first present environmental opportunities that necessitate improved solute–solute in separation. We then discuss mechanisms desired properties required for better selectivity. On basis most recent progress reported literature, examine key principles material design fabrication, which create membranes enhanced more highlight important roles surface engineering, nanotechnology, molecular-level improving Finally, prospects highly selective NF practical applications, identifying knowledge gaps will guide future research promote sustainability through tunable
