There has been significant attention on the efficient degradation of pollutants in wastewater using metal-organic frameworks (MOFs) photocatalytic methods over past decade. Herein, we examined elimination two different types water-contaminating dyes, specifically cationic dye methylene blue (MB) and anionic methyl orange (MO), through application bimetal Cu/Ni-BTC@SiO

The release of organic contaminants has grown to be a major environmental concern and threat the ecology water bodies. Persulfate-based Advanced Oxidation Technology (PAOT) is effective at eliminating hazardous pollutants an extensive spectrum applications. Iron-based metal-organic frameworks (Fe-MOFs) their derivatives have exhibited great advantages in activating persulfate for wastewater treatment. In this article, we provide comprehensive review recent research progress on significant potential Fe-MOFs removing antibiotics, dyes, phenols, other from aqueous environments. Firstly, multiple approaches preparing Fe-MOFs, including MIL ZIF series were introduced. Subsequently, removal performance such as antibiotics sulfonamides tetracyclines (TC), dyes rhodamine B (RhB) acid orange 7 (AO7), phenols phenol bisphenol A (BPA) by various was compared. Finally, different degradation mechanisms, encompassing free radical pathways non-free elucidated. This explores synthesis methods application bodies, providing insights further refining preparation Fe-MOFs.

Solvothermal reactions of cyclophosphazene-based hexacarboxylate (H6L) and rigid N-donor ligands (phen = phenantroline, trp 2,2′:6′,2″-terpyridine, 2,2′-bpy 2,2′-bipyridine, 4,4′-bpy 4,4′-bipyridine) resulted in four novel Cd(II) metal–organic frameworks (MOFs), formulated as ([(CH3)2NH2]+)[{Cd6(phen)2(L)2(HCOO)(H2O)}]·4DMF·3H2O (PCP-3), {Cd2(trp)2(H2L)}]·DEF·2H2O (PCP-4), [{Cd3(2,2′-bpy)2(L)(DMF)(H2O)}]·2DMF (PCP-5), [{Cd6(4,4′-bpy)2(L)2(H2O)9}]·5DMF·H2O (PCP-6). These MOFs have been successfully characterized using Fourier-transform infrared spectroscopy (FTIR), single crystal powder X-ray diffraction (SC PXRD), thermal analyses (TGA), scanning electron microscopy (SEM), ultraviolet–visible diffuse reflectance measurements (UV-DRS), solid-state photoluminescence measurements. SCXRD results indicated that the cyclotriphoshazene ligand coordinates with ions to give a wide variety structures ranging from one-dimensional (1D) tubular structure three-dimensional (3D) porous frameworks. PCP-3 shows 3D framework two secondary building units (SBUs) constructed trinuclear clusters. PCP-4 has π–π stacking 1D channels through strong face-to-face interactions. PCP-5 displays two-dimensional (2D) layered framework. PCP-6 exhibits which pillar 4,4-bpy coordinate ions. After removal guest molecules, PCP-3, PCP-4, PCP-5, substantial free volumes, are 21.04, 17.3, 17.0, 27.3%, respectively. All PCPs demonstrated high efficiency photocatalytically degrading organic dyes: methylene blue (MB), methyl orange (MO), rhodamine B (RhB), reactive 16 (RO16) under UVA light irradiation. A proposed photocatalytic mechanism, based on trapping experiments, identified O2•– •OH primary radicals involved dye degradation. exhibited remarkable activity, achieving up 95% degradation within 40 60 min. Additionally, showed excellent reusability maintained over five consecutive runs. In addition, characteristics were thoroughly examined.
