Applications of MOFs as Luminescent Sensors for Environmental Pollutants

Small, Journal Year: 2021, Volume and Issue: 17(22)

Published: Feb. 26, 2021

Abstract The environmental pollution has become a serious issue because the pollutants can cause permanent damage to DNA, nervous system, and circulating resulting in various incurable diseases, such as organ failure, malformation, angiocardiopathy, cancer. effective detection of is urgently needed keep them far away from daily life. Among reported pollutant sensors, luminescent metal–organic frameworks (LMOFs) with tunable structures have attracted remarkable attention detect their excellent selectivity, sensitivity, recyclability. Although lots framework (MOF)‐based sensors been summarized discussed previous reviews, pollutants, especially radioactive ions heavy metal ions, still not systematically presented. Here, sensing mechanisms construction principles MOFs are discussed, state‐of‐the‐art MOF‐based including pesticides, antibiotics, explosives, VOCs, toxic gas, small molecules, highlighted. This comprehensive review may further guide development promote practical applications for pollutants.

MOF Materials for the Capture of Highly Toxic H₂S and SO₂

Organometallics, Journal Year: 2020, Volume and Issue: 39(7), P. 883 - 915

Published: Jan. 15, 2020

Metal–organic frameworks (MOFs) are some of the most interesting and promising candidates to sequester toxic H2S SO2 gases. MOFs show advantages over classic porous materials due their chemical composition, ligand functionality, cavity dimensions, ease preparation, relatively low cost reactivation. The optimization physical–chemical interactions between molecules is key further amplification capture. Reversibility after adsorption can be modulated through noncovalent bonding functionalized ligands (within MOF structures) SO2. This review aims summarize recent advances in development MOF-based systems for capture removal We anticipate that this article offer very useful information on significant rapid progress enhancement by MOFs.
