Abstract
In the past decade, per- and polyfluorinated substances (PFAS) have garnered significant attention due to their widespread presence and detrimental environmental and health impacts. These compounds exhibit exceptional hydrophobicity, oleophobicity, chemical stability, and resistance to biodegradation, posing a significant threat to living organisms, particularly mammals. Numerous technologies have been employed for PFAS removal in which membrane filtration stands out as a highly effective approach, capable of removing different types of PFAS (anionic, cationic, and zwitterionic) with efficiencies exceeding 99 %. The advent of MXenes, a class of two-dimensional transition metal nitrides, oxycarbides, carbonitrides, and carbides, has revolutionized water treatment. MXene-based membranes, with their diverse elemental structure and ability to accommodate multiple surface functional groups, offer exceptional promise for PFAS removal. For the first time, all studies about PFAS removal via MXene-based membranes were summarized in this review article, and their performance was compared to commercial membranes. Moreover, the fabrication methods of MXene-based membranes were discussed in details. Finally, authors have given numerous suggestions about the future of PFAS removal via MXene-based membranes and explained what is missing currently.
期刊介绍:
Coordination Chemistry Reviews offers rapid publication of review articles on current and significant topics in coordination chemistry, encompassing organometallic, supramolecular, theoretical, and bioinorganic chemistry. It also covers catalysis, materials chemistry, and metal-organic frameworks from a coordination chemistry perspective. Reviews summarize recent developments or discuss specific techniques, welcoming contributions from both established and emerging researchers.
The journal releases special issues on timely subjects, including those featuring contributions from specific regions or conferences. Occasional full-length book articles are also featured. Additionally, special volumes cover annual reviews of main group chemistry, transition metal group chemistry, and organometallic chemistry. These comprehensive reviews are vital resources for those engaged in coordination chemistry, further establishing Coordination Chemistry Reviews as a hub for insightful surveys in inorganic and physical inorganic chemistry.
