The presence of persistent organic pollutants (POPs) in the aquatic environment is causing widespread concern due to their bioaccumulation, toxicity, and possible environmental risk. These contaminants are produced daily large quantities released into water bodies. Traditional wastewater treatment plants ineffective at degrading these pollutants. As a result, development long-term effective POP removal techniques critical. In water, adsorption photocatalytic degradation POPs have been identified as energy cost-efficient solutions. Both technologies received lot attention for efforts treat world's wastewater. Photocatalytic promising, effective, long-lasting method, while represents simple, practical particularly decentralized systems isolated areas. It critical develop new adsorbents/photocatalysts with desired structure, tunable chemistry, maximum sites highly efficient POPs. class recently created multifunctional porous materials, Metal-organic frameworks (MOFs) offer tremendous prospects adsorptive remediation.

Water is a supreme requirement for the existence of life, contamination from point and non-point sources are creating great threat to water ecosystem. Advance tools techniques required restore quality metal-organic framework (MOFs) with tunable porous structure, striking physical chemical properties an excellent candidate it. Fe-based MOFs, which developed rapidly in recent years, foreseen as most promising overcome disadvantages traditional depolluting practices. Fe-MOFs low toxicity preferable stability possess performance potential almost all remedying contrast other MOF structures, especially visible light photocatalysis, Fenton, Fenton-like heterogeneous catalysis. become essential tool treatment due their high catalytic activity, abundant active site pollutant-specific adsorption. However, structural degradation under external chemical, photolytic, mechanical, thermal stimuli impeding further improvement activity commercialization. Understanding shortcomings integrity crucial large-scale synthesis commercial implementation Fe-MOFs-based techniques. Herein we summarize synthesis, structure advancements remediation methods using particular more attention paid adsorption, catalysis photocatalysis clear insight into mechanisms involved. For ease analysis, pollutants have been classified two major classes; inorganic organic pollutants. In this review, present first time detailed challenges employing instability.

The photocatalytic degradation of methylparaben was investigated under simulated solar light using a synthesised metal–organic framework (UiO-66-NH2). For that purpose, the pollutant spiked in different water matrices: distilled water, from Lima River (Northwestern Portugal), and urban wastewater. Complete removal achieved 1 h reaction. In natural matrices, performance decreased to 70% after 3 reaction, owing physical–chemical properties samples. UiO-66-NH2 photocatalyst revealed high stability continuous mode, reaching steady state 5 h, which percentage kept constant for 25 h. gave five main reaction byproducts four short-chain carboxylic acids, identified by LC/ESI-MS UHPLC analyses, respectively. mechanism selective scavengers.
