The application of metal-organic frameworks (MOFs) towards the adsorption antibiotics is a new and emerging area study. rise in use or misuse antibiotic products has exacerbated their ongoing presence persistence natural environment. Even at low concentrations, residues exert pressure on bacterial populations, eventually leading to emergence resistant bacteria. Metal-organic frameworks, known for high porosity, vast specific surface area, ease modification, have emerged be promising sustainable adsorbent. In an effort advance development this adsorbent, study provides state-of-the-art review recent research published from 2020 present, specifically examining MOFs removing aqueous solutions. Multiple MOF adsorbents were analyzed, with approximately 59% demonstrating significant capacity within pH range 6.0-8.0. 75% instances, system reached equilibrium under 2 hr. Adsorption capacities compared well other works literature exceeded conventional many instances. Notable cases performance MIL-53(Al) amoxicillin (AMX) SA-g-P3AP@MOF(Fe)/Ag neomycin where 758.5 625.0 mg/g attained, respectively. reusability was extensively reported laboratory batch scale. Analysis studies revealed most effective eluents acetone, ethanol, methanol, mostly 3-5 cycles attainable without appreciable loss efficiency. confirmed that are highly efficient antibiotics; however, there some areas warrant further development. It intended work will bring trends forefront, identify knowledge gaps, help guide future proposals.

In this work, an Eu coordination polymer (1a) was synthesized by a single-crystal-to-single-crystal transformation based upon complex 1 under the stimulation of water molecules ({[Eu(bpdc)1.5(H2O)5]·4H2O}n (1a), {[Eu2(bpdc)3(H2O)2]·5H2O}n (1), and H2bpdc = 2,2'-bipyridine-3,3'-dicarboxylic acid ligand). Complex 1a exhibited considerable pH fluorescence stability in aqueous solution. Notably, experiment showed that achieved high selectivity sensitivity for detection notorious food additive melamine (MEL) through significant enhancement response; yet had no fluorescent response with MEL. Furthermore, recognition mechanism on MEL explored detail combination experimental studies DFT calculations. It worth pointing out proton conductivity significantly improved compared due to increase hydrogen-bonding interactions framework.

Abstract Herein, a variety of 2,6‐diaminopyridine (DAP) derived nitrogen‐doped hierarchically porous carbon (DAP‐NHPC‐T) prepared from carbonization‐induced structure transformation DAP‐Zn‐SiO 2 ‐P123 nanocomposites are reported, which facilely solvent‐free co‐assembly block copolymer templates P123 with pyridine‐rich monomer DAP, Zn(NO 3 ) and tetramethoxysilane. In the pyrolysis process, SiO promote formation mesoporous supermicroporous structures in DAP‐NHPC‐T, while high‐temperature volatilization Zn contributed to generation micropores. The DAP‐NHPC‐T possess large BET surface areas (≈956–1126 m g −1 ), hierarchical porosity micro‐supermicro‐mesoporous feature high nitrogen contents (≈10.44–5.99 at%) tunable density pyridine‐based sites (≈5.99–3.32 at%), exhibiting good accessibility reinforced interaction SO . Consequently, show capacity (14.7 mmol , 25 °C 1.0 bar) /CO /N IAST selectivities, extraordinary dynamic breakthrough separation efficiency cycling stability, far beyond any other reported metal‐free carbon. As verified by situ spectroscopy theoretical calculations, boost adsorption via unique charge transfer, mechanism reaction model have been finally clarified.
