Advanced porous nanomaterials as superior adsorbents for environmental pollutants removal from aqueous solutions

Critical Reviews in Environmental Science and Technology, Год журнала: 2023, Номер 53(13), С. 1289 - 1309

Опубликована: Янв. 23, 2023

Advanced porous nanomaterials such as metal-organic frameworks (MOFs), covalent organic (COFs), and aromatic (PAFs) with high specific surface areas, abundant functional groups, accessible pore structures, tunable sizes, easy modification are attractive adsorbents for the capture of toxic heavy metal ions, pollutants, radionuclides from aqueous solutions. This review first comprehensively introduces properties MOFs, COFs, PAFs to highlight their advantages adsorbents. Subsequently, recent progress superior efficient removal environmental pollutants is summarized. Furthermore, influences conditions information about interaction mechanisms between advanced discussed. Finally, applications promising prospects in pollution management beneficial designing fabricating materials, which also provides some meaningful guidance studying adsorption materials pollutants.

“Functional upcycling” of polymer waste towards the design of new materials

Chemical Society Reviews, Год журнала: 2023, Номер 52(14), С. 4755 - 4832

Diversification of polymer waste recycling is one the solutions to improve current environmental scenario. Upcycling a promising strategy for converting into molecular intermediates and high-value products. Although catalytic transformations small molecules have been actively discussed, methods characteristics upcycling new materials not yet addressed. Recently, functionalisation wastes (polyethylene terephthalate bottles, polypropylene surgical masks, rubber tires, etc.) their conversion with enhanced functionality proposed as an appealing alternative dealing recycling/treatment. In this review, term 'functional upcycling' introduced designate any method post-polymerisation modification or surface without considerable chain destruction produce upcycled material added value. This review explores functional detailed consideration most common polymers, i.e., polystyrene, poly(methyl methacrylate), polyethylene, polypropylene, polyurethane, polyethylene terephthalate, polyvinyl chloride, polycarbonate, rubber. We discuss composition plastic waste, reactivity, available physical/chemical agents modification, interconnection between properties application. To date, successfully applied adsorbents (including CO2), catalysts, electrode energy storage sensing, demonstrating high Importantly, reviewed reports indicated that specific performance generally comparable higher than similar prepared from virgin feedstock. All these advantages promote diversification approach against postprocessing employed waste. Finally, identify limitations suggest future scope research each polymer, we comparatively analysed aspects those chemical mechanical recycling, considering resource costs, toxicity used chemicals, footprint, value product.

MOFs and MOF-Derived Materials for Antibacterial Application

Journal of Functional Biomaterials, Год журнала: 2022, Номер 13(4), С. 215 - 215

Опубликована: Ноя. 3, 2022

Bacterial infections pose a serious threat to people’s health. Efforts are being made develop antibacterial agents that can inhibit bacterial growth, prevent biofilm formation, and kill bacteria. In recent years, materials based on metal organic frameworks (MOFs) have attracted significant attention for various applications due their high specific surface area, enzyme-like activity, continuous release of ions. This paper reviews the progress MOFs as agents, focusing preparation methods, fundamental mechanisms, strategies enhance effects. Finally, several prospects related application proposed, aiming provide possible research directions in this field.

Binder-free Three-dimensional (3D) printing of Cellulose-ZIF8 (CelloZIF-8) for water treatment and carbon dioxide (CO2) adsorption

Chemical Engineering Journal, Год журнала: 2023, Номер 468, С. 143567 - 143567

Опубликована: Май 25, 2023

Metal-organic frameworks (MOFs) have advanced several applications, including energy, biomedical and environmental remediation. However, most of the reported MOF materials are in powder form limiting their applications. This study processing via three-dimensional (3D) printing cellulose-MOFs (denoted as CelloMOFs). The 3D procedure involved a one-pot method three steps: gel formation, printing, in-situ growth crystals. offered CelloMOF binder-free with high loading 67.5 wt%. 3D-printed porous structures were used adsorbents for carbon dioxide (CO2), dye, heavy metal ions. They can be also catalysts degradation water pollutants such organic dyes. separated easily without requiring extra procedures centrifugation or filtration. complete (>99%) removal dyes within 10 min selectivity toward anionic e.g, methyl blue (MeB). exhibited CO2 ions adsorption capacities 0.63 mmol/g (27.7 mg/g) 8–328 mg/g, respectively, good recyclability. Our methodology will open new venues its applications treatment air purification.
