Iron-based metal-organic frameworks (MOFs) have aroused extensive concern as prospective photocatalysts for antibiotic (e.g., tetracycline, TC) degradation. However, efficiencies of single and simple Fe-based MOFs still undergo restricted light absorption weak charge separation. Assembly different iron-based MOF building blocks into a hybrid MOF@MOF heterostructure reactor could be an encouraging strategy the effective capture antibiotics from aqueous phase. This paper reports new-style MIL-101(Fe)@MIL-100(Fe) photocatalyst, which was groundbreakingly constructed to realize double win boosting performances adsorption photocatalysis. The optical response range, surface open sites, separation efficiency can regulated through accurate design alteration. Attributed synergistic effects MOFs, exhibits excellent photocatalytic activity toward TC degradability compared MIL-101(Fe) MIL-100(Fe), is even superior those reported previously in literature. Furthermore, main active species •O2- h+ were proved trapping tests process. Additionally, possesses remarkable stability, maintaining more than 90% initial after fifth cycle. In brief, highly efficient Our work offers new visible-light photodegradation by exploring composite.

The appeal of metal–organic frameworks (MOFs) in wastewater treatment is tempered by their polycrystalline, powdery state, and challenges associated with deployment. In the case UiO-66, one most stable widely-used MOFs, a low tendency for removing some organic contaminants has been observed on top mentioned issues. To address these challenges, herein, we take two complementary steps, i.e., hybridization UiO-66 nanodiamond (ND) followed integration hybrid nanoparticles electrospun polymeric nanofibers based chitosan/polyvinyl alcohol (PVA). We present electrospinning polymer/MOFs as promising technique to fabricate highly efficient adsorbents water remediation. use chitosan/PVA (ECPN) versatile host MOF that remove cationic methylene blue anionic Congo red dyes. Four nanofiber composites containing thermally oxidized (TOND), ND, [email protected] are utilized unravel effect type loading dye adsorption capacity. It shown incorporation small ECPN significantly enhaces maximum More importantly, rationally engineered exhibit best performance adsorption; instance, an 80 % increase capacity, from 769 1429 mg/g, recorded loaded compared unfilled ECPN. On that, designed adsorbent showed appreciable regeneration ability after 6 adsorption–desorption cycles. All all, this study offers new generation advanced materials emerging streams.
