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.

Abstract The photocatalytic transformation of carbon dioxide (CO 2 ) into carbon‐based fuels or chemicals using sustainable solar energy is considered an ideal strategy for simultaneously alleviating the shortage and environmental crises. However, owing to low utilization sunlight inferior catalytic activity, conversion efficiency CO photoreduction far from satisfactory. In this study, a MOF‐derived hollow bimetallic oxide nanomaterial prepared efficient . First, unique ZIF‐67‐on‐InOF‐1 heterostructure successfully obtained by growing secondary Co‐based ZIF‐67 onto initial InOF‐1 nanorods. corresponding counterpart has larger specific surface area after acid etching, oxidized H‐Co 3 O 4 /In material exhibits abundant heterogeneous interfaces that expose more active sites. band structure corresponds well with photosensitizer [Ru(bpy) ]Cl , which results in high yield 4828 ± 570 µmol h −1 g stable activity over consecutive six runs, demonstrating adequate performance. This study demonstrates rational design MOF‐on‐MOF heterostructures can completely exploit synergistic effects between different components, may be extended other nanomaterials as promising catalysts practical storage.

Langmuir, Journal Year: 2024, Volume and Issue: 40(31), P. 16642 - 16652

Published: July 25, 2024

CoFe2O4 has potential for application as a magnetically recoverable visible-light photocatalyst, but its photocatalytic activity is encumbered by the high recombination probability of photogenerated holes (h+) and electrons (e–). This work was undertaken to boost photocatalysis through coupling with conjugated poly(vinyl chloride) derivative (CPVC). An easily implementable solvothermal−liquid solid mixing−evaporation solvent−pyrolysis method exploited synthesize CoFe2O4/CPVC nanocomposites. The capabilities products were assessed photocatalyzing reduction Cr(VI) under (λ > 420 nm). results demonstrate that optimal nanocomposite (CoFe2O4/CPVC-2) markedly heightened (3.6 times CoFe2O4) competent reusability recoverable. Furthermore, CoFe2O4/CPVC-2 also shows superior performance toward treatment diluted Cr(VI)-containing passivation solution copper alloys. It deduced based on photoelectricity measurement increased chiefly attributed p–n heterojunction structure, which greatly elevates h+–e– separation transfer efficiency. When waste PVC plastic films (replacing new pure powder) utilized synthesis, obtained exhibited even better (4 CoFe2O4). not only made recoverable, efficient photocatalyst decontamination in water inspirational recycling produce high-valued photocatalysts.
