The Preparation and Application in Adsorptive Removal Hazardous Materials of MOF-Derived Materials

Metal–Organic Framework-Based Composites for the Adsorption Removal of Per- and Polyfluoroalkyl Substances from Water

“…Additionally, the organic ligands of MOFs contain functional groups, such as −COOH, −OH, and −NH 2 . , These functional groups can act as both hydrogen bond donors and acceptors, which is beneficial for the adsorption of PFASs on MOFs. However, the hydrogen bonding can be significantly affected by the pH level of the sample, such as strong acidity and alkalinity . It is noteworthy that MOFs can not only form hydrogen bonding with PFASs but also adsorb other substances in water, including humic acids, etc .…”

“…The hydrophobicity of MOFs is closely related to their surface chemical properties, structural morphology, and surface roughness . MOFs with a high specific surface area and a microporous framework reduce the contact between the material and air, consequently leading to an increased in the contact angle between the material and water . The incorporation of hydrophobic groups and the introduction of rough surfaces can significantly augment the hydrophobicity of MOFs .…”

“…MOFs with a high specific surface area and a microporous framework reduce the contact between the material and air, consequently leading to an increased in the contact angle between the material and water . The incorporation of hydrophobic groups and the introduction of rough surfaces can significantly augment the hydrophobicity of MOFs . This type of force is particularly important in the adsorption of medium- and long-chain PFASs, because it is less susceptible to interference in complex matrices.…”

A Luminescent Cd-MOF Used as a Chemosensor for High-Efficiency Sensing of Fe3+, Cr(IV), Trinitrophenol, and Colchicine

“…Environmental pollution has grown in importance as a global concern for public health and the ecosystem over the past few decades due to social development, and many types of pollutants such as nitroaromatic compounds, heavy metal ions, toxic anions, and colchicine are associated with health risks. Chemical synthesis and production of explosive materials are two common uses of nitroaromatic compounds (NACs), such as nitrobenzene (NB), 2,4,6-trinitrotoluene (TNT), and trinitrophenol (TNP), and they pose a substantial risk to human health and social security since they can contaminate air, groundwater, and soil . TNP is the most dangerous among these explosives because of its tremendous explosive strength and numerous uses in dye, leather, explosive manufacturing, textile, and pharmaceutical industries …”

A review of metal–organic framework (MOF) materials as an effective photocatalyst for degradation of organic pollutants

“…3 In response to the freshwater crisis, water purication has emerged as an alternative drinking and industrial water supplementation solution. 4,5 Therefore, developing efficient technologies that effectively remove contaminants from wastewater becomes crucial, ensuring environmental stability. 6,7 Based on the Safe Drinking Water Act (SDWA), contaminants can be categorized as organic and inorganic, depending on their chemical composition.…”
