An overview of metal-organic frameworks and their magnetic composites for the removal of pollutants

Separation and Purification Technology, Journal Year: 2023, Volume and Issue: 320, P. 124144 - 124144

Published: May 24, 2023

As a result of serious pollution in the water environment, sewage disposal has been receiving lot attention from industry. Metal-organic frameworks (MOFs) attract interest adsorption and separation due to their complex structures easily adjustable pore sizes. Magnetic MOFs inheriting advantages both large surface area easy recovery have great potentials pollutants. This paper reviews recent research progress on ions, dyes other contaminants by different types (magnetic non-magnetic MOFs) magnetic composites (Fe3O4@MOF) aqueous environments. The factors affecting pollutants, thermodynamic kinetic effects are discussed with detailed examples. Finally, challenges opportunities for further development elucidated.

A review of emerging micro-pollutants in hospital wastewater: Environmental fate and remediation options

Results in Engineering, Journal Year: 2022, Volume and Issue: 16, P. 100671 - 100671

Published: Sept. 28, 2022

Hospitals played vital role in the maintenance and sustenance of human health. However, hospital activities generate high volume toxic solid liquid containing diverse inorganic, organic microbial wastes released untreated into ecosystem. The management wastewater particular has been a major source concern due to presence unregulated emerging micro-pollutants at concentrations range ng/L μg/L. These pollutants low concentration exert different potential health effects on aquatic species. In this review, formation, composition, properties ecotoxicology selected (Norfloxacin, Ofloxacin, Ciprofloxacin, Clofibric acid Carbamazepine) were reviewed. review also elucidates detection quantification micropollutants by Spectrophotometry techniques, Gas Chromatography, Ion Chromatography-Mass spectrometry, High-Performance Liquid Chromatography. Furthermore, treatment through physical, biological, chemical, adsorption advanced oxidation processes such as photocatalysis photo-Fenton including their operational mechanism provided. chemistry degradation several intermediates It was found that conventional methods are not designed for effective removal these because they exist mixtures very exerts toxicological effects. reveals no single technology can effectively detoxify wastewater, instead combination (phototcatalytic/adsorption or photo-fenton/adsorption) most appropriate treatment. Finally, regular monitoring determination physicochemical ecotoxicological parameters recommended.

Trace to the Source: Self‐Tuning of MOF Photocatalysts

Advanced Energy Materials, Journal Year: 2023, Volume and Issue: 13(23)

Published: April 23, 2023

Abstract Benefitting from ultra‐high porosity, large specific surface area (SSA), and rich active sites, metal–organic frameworks (MOFs) have emerged as a star material in energy environment related applications, especially photocatalysis. In comparison with conventional photocatalysts, MOFs can be customized terms of electronic structure, photo‐responsiveness, morphological dimensions by rational design, which means that eliminate the need for other species to achieve enhanced photocatalytic performance, such metals, compounds, polymers, may introduce extra costs, time‐consuming, multi‐phase, or an unclear mechanism. Most previous review works MOF photocatalysis mixed self‐tuning assisted‐tuning, often gives incomplete understanding. this work, self‐tunning analyzing component (as clusters, ligands, inclusions), defect (defect engineering, linkers, oxygen vacancies (OVs), crystal facets, dimensions, amorphization) is summarized. Then, outstanding examples these strategies applied water redox, CO 2 /N reduction, organic conversion, environmental treatment are discussed. Finally, opportunities challenges faced analyzed different perspectives. This paper comprehensive systematic on enhance activity.
