MOFs meet membrane: application in water treatment and separation

Abstract

Metal-organic frameworks (MOFs) are a class of solid crystalline materials formed by the self-assembly of organic ligands and metal ions or clusters through coordination bonds. Owing to their intrinsic rich...

Synergy of Ligands in Tailoring the Photocatalytic Properties of Zirconium Metal–Organic Framework-Impregnated Membranes for Water Treatment

“…It should be noted that the water contact angle property can be associated with the interaction of water on the surface of the membrane, whereas the water uptake can be associated with the flow of water through the membranes. These features positively support the overall improved filtration performance of ZMM-ATP membranes. , …”

Recent progress in 2D and 3D metal–organic framework-based membranes for water sustainability

“…MOFs are a fascinating class of porous materials that are composed of metal ions (nodes) or clusters coordinated with organic ligands (secondary building blocks), forming a highly porous crystalline framework. [1][2][3] A controllable porosity (0.5 nm to 2.0 nm), high stability, and well-defined pores provide significant advantages in energy storage and conversion, biomedicines, chemical sensors, photocatalysis, gas storage and separation, and water desalination applications. [4][5][6] There are many ways to classify MOFs, e.g., Isoreticular metalorganic frameworks (IRMOFs), zeolitic imidazolate framework materials (ZIFs), and porous coordination networks (PCNs), depending on the source of the configuration (Fig.…”

A hydrophobic–superoleophilic 2D Zr-based alkyne-rich metal–organic framework for oil/water separation and solar-assisted oil evaporation

“…Attractive as these tactics seem, some negative concerns deserve attention: (1) the preparation of peruorinated/multi-alkylated linkers is sometime tedious; (2) the reproducibility of post-synthetic modication is not guaranteed, giving rise to varying performance; (3) some MOF composites involve time-consuming multi-step preparation. Setting aside these problems, MOFs have been fabricated with other materials to build a composite that merges photothermal conversion and oil/water separation [32][33][34][35][36][37][38] for self-cleaning oil/ water separation, a more practical execution of water purication and oil extraction.…”
