Summary: This study developed a new type of adsorbent ACNF/PANI/MIL-101(Cr)-NH2, which can efficiently remove the pollution of nonsteroidal anti-inflammatory drugs (IDM) with its high adsorption capacity and superior adsorption performance. The experimental results showed that the adsorption mechanism of the adsorbent was mainly related to electrostatic interaction, hydrogen bonding, and π-π interaction. This work provides a feasible strategy for developing advanced adsorbents in practical wastewater treatment.

Summary: In this study, a flower-like BiVO4/MIL-101-NH2 composite is synthesized by a simple and surfactant-free method. The construction of the -COO--Bi3+ ionic bond enhances the interface affinity between BiVO4 and MIL-101-NH2. The improved separation and transportation rates of charge carriers are achieved due to the efficient light capture, sufficient electron traps, and formation of a heterostructure. Additionally, the MIL-101-NH2/BiVO4 composite exhibits excellent photocatalytic removal of Cr(VI) (91.2%), and FNBV-3 (Fe/Bi = 0.25) shows good reusability after five cycles.

Summary: In this study, a chromium-based metal-organic framework (MIL-101-NH2) was modified with thiourea and formaldehyde to form a polymeric layer on the surface (MIL-101-NH2-TFR). The resulting nanohybrid was found to have a superior adsorption performance for iodine capture compared to the pristine MIL-101-NH2. Quantum chemical calculations were conducted to reveal the mechanism of iodine adsorption onto the surface of MIL-101-NH2-TFR.

Summary: Photocatalytic oxidative desulfurization (PODS) using efficient Ce-doped MIL-125-NH2 photocatalysts was successfully achieved for the removal of dibenzothiophene (DBT) under mild reaction conditions. The high performance was attributed to the high surface area and the formation of Ce-Ti-oxo clusters, as well as the valence transformation of Ce4 + /Ce3 + and Ti4 + /Ti3 + redox mediators. Increasing the reaction temperature was found to enhance the PODS performance, and a thermo-enhanced PODS mechanism was proposed.

Summary: A promising Z-scheme NH2-MIL-101(Fe)/BiVO4 heterostructure was fabricated and employed for the first time for ammonia nitrogen removal in water, showing boosted performance. The 10%-MBVO exhibited optimal removal rate of ammonia nitrogen as 95.7% and N2 selectivity as 92.3% in 90 min at pH of 9.0 with initial concentration as 30 mgN/L. The mechanism behind the enhancement was attributed to the improved light harvesting capacity and stronger redox ability provided by the Z-scheme heterostructures.

Summary: A novel highly dispersed NH2-MIL-101(Fe)/carboxylated g-C3N4 heterostructure was prepared using a facile oil bath method. The chemical bonding interaction promoted the heterogeneous nucleation and growth, resulting in nanometer-sized granular morphology of NM-101(Fe) uniformly dispersed on CCN surface. The 10% NM-101(Fe)/CCN heterostructure exhibited high removal efficiency for Cr(VI) and ciprofloxacin (CIP) pollutants.

Summary: A series of stable nano-Ag-doped NH2-MIL-125(Ti) composites were prepared via hydrothermal and photo reduction method. The composites exhibited good visible-light absorption ability with evenly distributed Ag nanoparticles on the surface of NH2-MIL-125(Ti). The optimal composite A/M125-20 showed a photocatalytic rate 2.7 times higher than pure M125, achieving a final degradation rate of 97.4% for Rhodamine B within 120 min. O-2(-) and h(+) were identified as the main reactive species in the photocatalytic degradation process.

Summary: This study reports the direct electrochemical synthesis of four iron-based MOFs via controlled potential oxidation of dissolved metal cations. It represents the first general route that employs interfacial electrochemistry to alter the oxidation state of metal ions dissolved in solution to directly trigger MOF formation. The reported method is functional group tolerant and broadly applicable to the bulk synthesis or surface growth of a range of MOFs based on metal ions with accessible oxidation states.

Summary: Cu-doped MIL-101(Fe) has been used for the first time in photocatalytic nitrogen fixation, showing three times higher activity compared to MIL-101(Fe). The Cu doping not only increases the specific surface area and photoreduction capability, but also enhances nitrogen adsorption and activation capacity. The combination of metal ions doping and components regulation of MOFs provides future opportunities to enhance photocatalytic nitrogen fixation activity.

Summary: Competition for adsorption sites between atmospheric moisture and volatile organic compounds can significantly impact the VOC removal performance of metal-organic framework adsorbents like MIL-101. In this study, a vapor phase deposition of polydimethylsiloxane (PDMS) was used to create more hydrophobic MIL-101 composites, resulting in enhanced internal hydrophobicity and intact porosity. The MIL-101-PDMS composite showed superior performance in capturing toluene, exhibiting higher adsorption capacity and overall capture rate compared to pristine MIL-101, and maintaining excellent structural stability and adsorption performance after multiple sorption/desorption cycles.
