A self-cleaning hydrophobic MOF-based composite for highly efficient and recyclable separation of oil from water and emulsions

Abstract

A hydrophobic MOF (1′@CF3) was synthesized by post-synthetic modification to anchor -CF3 group to the Zr- BDC-OH MOF (1′). The hydrophobic property of the MOF was used for the preparation...

An eco-friendly approach using a nonfluorous self-cleaning metal–organic framework composite and membrane for oil–water separation

“…The concentrated solution of the polymer caused the blockage of the pores of the dopamine-treated sponge in our previous work. 8 But after diluting the polymeric solution, the sponge's pores are more available to absorb the oils. The same polymeric solution was also utilized to synthesize a polymer–MOF-coated silk membrane.…”

“…Synthesis and characterization of the superhydrophobic SH-UiO-66′@sponge composite and the SH-UiO-66′@silk membrane A superhydrophobic polymer-MOF composite and a membrane were synthesized following the previous work from our group with slight modifications. 8 In the first step, 2 × 2 × 2 cm 3 size melamine sponges were cleaned by sonicating in a mixture of ethanol and acetone. Afterward, 160 mg of dopamine was taken in 80 mL solution of a 1 : 1 mixture of ethanol and water.…”

Eco-Friendly Fluorine Functionalized Superhydrophobic/Superoleophilic Zeolitic Imidazolate Frameworks–Based Composite for Continuous Oil–Water Separation

“…Incorporation of short fluorine-carbon chain substances that contain amine groups in ZIF-90 via a Schiff base condensation reaction is likely a promising method to improve its hydrophobicity. The trifluoromethyl (CF 3 ) group has been widely used in previous studies to increase the hydrophobicity of materials due to its extremely low surface energy [ 40 , 41 ]. Thus, eco-friendly short-chain fluorinated molecules containing NH 2 groups such as 2,2,2-trifluoroethylamine should be seriously considered to improve the hydrophobicity of ZIF-90.…”

A MOF chemosensor for highly sensitive and ultrafast detection of folic acid in biofriendly medium, paper strips and real samples

“…On the other hand, MOF-based probes have become very prevalent for the selective detection of numerous analytes. [31][32][33][34][35][36][37][38] Their three-dimensional (3D) frameworks, 39 made of metal ions and organic linkers, 57 enable wide surface area, high thermal stability and scope of functionalisation of the pore surface. 33,[40][41][42][43][44] The functionalised organic linker is strongly bound in this framework, decreasing the scope of aggregation.…”
