Abstract ：
Environmental concerns are driving the development of eco-friendly and effective methods for contaminant monitoring and remediation. In this study, a lanthanide porphyrin-based MOF with dual fluorescence sensing and photocatalytic properties was synthesized and applied for the detection and combined removal of Cr(VI) and ciprofloxacin (CIP). Using different excitation wavelengths, the material exhibited selective detection of Cr(VI) via fluorescence quenching and CIP through fluorescence enhancement. The variation in color intensity of Tb-MOF on 3D EEM spectra enabled simultaneous detection of both contaminants. Additionally, Tb-MOF demonstrated a synergistic removal effect, achieving over 95% removal rates of Cr(VI) and CIP within 90 min, with consistent sensing and catalytic performance across four cycles. Mechanistic investigations revealed that (i) strong coordination between Tb3+ and CIP altered the surface potential of Tb-MOF, enhancing Cr(VI) adsorption; (ii) as an efficient electron acceptor, Cr(VI) promoted electron transfer and its reduction to Cr(III); and (iii) superoxide radicals generated via a type I mechanism played a key role in CIP degradation. This research underscores the potential of Tb-MOF as a multifunctional platform for simultaneous detection and synergistic remediation of mixed pollutants.

Abstract ：
The development of innovative multi-emission sensors for the rapid and accurate detection of contaminants is both vital and challenging. In this study, utilizing two rigid ligands (H3ICA and H4BTEC), a series of water-stable bimetallic organic frameworks (EuTb-MOFs) were synthesized. Luminescent investigations have revealed that EuTb-MOF-1 exhibits prominent multiple emission peaks, attributed to the distinctive fluorescence characteristics of Eu(III) and Tb(III) ions. Therefore, EuTb-MOF-1 efficiently recognized various metal ions and pharmaceutical compounds through 2D decoded maps. Fe3+ and Pb2+ exhibited significant quenching effects on the luminescence of EuTb-MOF-1, which were attributed to the internal filtering effect and the interaction between Lewis basic sites within EuTb-MOF-1 and Pb2+ ions, respectively. Furthermore, EuTb-MOF-1 demonstrated high sensitivity to sulfonamide antibiotics, with detection limits of 0.037 μM for SMZ and 0.041 μM for SDZ, respectively. In addition, EuTb-MOF-1 was immobilized to prepare MOF-based test strips, enabling direct visual detection of sulfonamides as a portable sensor. With excellent water stability, multi-responsive recognition capabilities, and high sensitivity to specific analytes, EuTb-MOF-1 is a promising candidate for environmental contaminant detection in aquatic systems. © 2024

Abstract ：
Thousands of chemicals have been released into the environment in recent decades. The presence of emerging contaminants (ECs) in water has emerged as a pressing concern. Adsorption is a viable solution for the removal of ECs. Metal-organic frameworks (MOFs) have shown great potential as efficient adsorbents, but their dispersed powder form limits their practical applications. Recently, researchers have developed various separable MOF-based adsorbents to improve their recyclability. The purpose of this review is to summarize the latest developments in the construction of separable MOF-based adsorbents and their applications in adsorbing ECs. The construction strategies for separable MOFs are classified into four categories: magnetic MOFs, MOF-fiber composites, MOF gels, and binder-assisted shaping. Typical emerging contaminants include pesticides, pharmaceuticals and personal care products, and endocrine-disrupting compounds. The adsorption performance of different materials is evaluated based on the results of static and dynamic adsorption experiments. Additionally, the regeneration methods of MOF-based adsorbents are discussed in detail to facilitate effective recycling and reuse. Finally, challenges and potential future research opportunities are proposed, including reducing performance losses during the shaping process, developing assessment systems based on dynamic purification and real polluted water, optimizing regeneration methods, designing multifunctional MOFs, and low-cost, large-scale synthesis of MOFs. © 2024 American Chemical Society.

Abstract ：
The semiconductor-insulator heterostructure, characterized by outstanding economic-efficiency and catalytic activity, represents a promising photocatalyst for practical pollutants degradation. However, achieving energy band matching between semiconductors and insulators remains a challenge. In this study, we meticulously designed and synthesized a band-matched semiconductor-insulator photocatalysts (AgI-BaCO3), leveraging the in-situ nucleation of ultrafine AgI nanoparticles on BaCO3 surface. The finely crafted heterostructure notably enhanced degradation efficiency of tetracycline over both pure AgI and BaCO3, demonstrating a remarkable pseudo-first-order kinetic rate constant that surpassed them by 27.2 and 33.5 times, respectively. The density functional theory calculations uncovered that the intense covalent interaction between AgI and BaCO3 established a specific channel for interfacial charge carriers. The generated CO3·- radicals as the main active species markedly expedited the removal of antibiotics. Furthermore, the catalysts demonstrated robust activity in real wastewater and surface water. This work supplies a novel reference for constructing insulator-based photocatalysts and elucidates its potential application in actual aquatic environments. © 2024 Elsevier B.V.

Abstract ：
The treatment of emerging contaminants is essential but challenging. Herein, a novel MOF/PAN fibrous composite (TCPP@UiO-66/PAN) was synthesized and used as a self-cleaning membrane for the efficient removal of a typical emerging contaminant, diclofenac sodium (DF). The introduction of the secondary linker tetra(4carboxyphenyl)porphyrin (TCPP) served to expand the pores and enhance its photocatalytic activity. TCPP@UiO-66/PAN shows higher adsorption capacity and initial adsorption rate than UiO-66/PAN. The maximum adsorption capacity of DF on TCPP@UiO-66/PAN reached 202 mg/g by Langmuir model. The DF adsorption mechanism involves the pi-pi/anion-pi interaction, Lewis acid-base interaction, and hydrogen bonding. Based on the dynamic filtration experiment, TCPP@UiO-66/PAN exhibited a remarkable treatment capacity for DF-contaminated water, measuring 3.75 x 104 kg/kg. Given its fibrous membrane structure, TCPP@UiO-66/ PAN could be easily separated from water and reused. In-situ photo-regeneration emerged as a highly effective method for regenerating TCPP@UiO-66/PAN after reaching adsorption saturation, with over 95 % DF degradation achieved under sunlight irradiation. The decomposition of DF primarily resulted from the generation of h+ and 1O2. Additionally, TCPP@UiO-66/PAN exhibited notable antibacterial properties when exposed to visible light. In vitro cytotoxicity assessments further confirmed the safety of these MOF/PAN composites. Combining the advantages of hybrid-linker strategy and fibrous composite, this work provided new insight into constructing MOF-based functional material for wastewater purification.

Abstract ：
The adsorptive removal of typical pharmaceuticals, carbamazepine (CBZ) and tetracycline (TC), was investigated with four zirconium-based porphyrinic metal-organic frameworks (MOFs) (PCN-221, PCN-222, PCN-223, and PCN-224). For both CBZ and TC, the adsorption capacities of the PCNs were ranked in the following order: PCN-221 < PCN-223 < PCN-224 < PCN-222. Notably, this order aligns with the BET surface areas of the PCNs. Cage-type PCN-221 showed a lower adsorption capacity than the other three channel-type MOFs due to its small apertures, which were not conducive to the activation of PCN-221 and space utilization. The amount of adsorption was proportional to the cumulative pore volume in PCNs with a width larger than that of the CBZ/TC molecule. Therefore, with high pore volume and large one-dimensional channels formed by ordered linker vacancies, PCN-222 was the best adsorbent in this work. According to the Langmuir model, PCN-222 exhibited exceptional adsorption capacities for CBZ and TC, reaching 305 mg/g and 280 mg/g, respectively. Additionally, the mechanisms for CBZ removal involved hydrogen bonding and pi-pi interactions/stacking, while electrostatic interactions, hydrogen bonding, and pi-pi interactions/stacking played crucial roles in TC adsorption onto MOFs. These findings establish a profound comprehension of the interplay between pore structure and performance, providing helpful guidance for designing MOFs to remove emerging contaminants effectively.

Abstract ：
The construction of step-scheme (S-scheme) heterojunctions has emerged as a widely adopted strategy for achieving photocatalytic hydrogen peroxide (H2O2) generation. In this study, we employed an approach to deposit indium sulfide (In2S3) onto a Schiff-base covalent organic framework (COF), namely TpMA, for H2O2 photosynthesis and its sterilization application. The optimized photocatalyst, 10%TpMA/In2S3, exhibited remarkable photocatalytic performance, yielding a substantial H2O2 output of 311.07 mu mol/L. A series of advanced instrumental analyses and density functional theory (DFT) results indicated that the establishment of the S-scheme heterojunction played a pivotal role in facilitating efficient charge carrier transfer and separation. Specifically, the formation of a built-in electric field was probed and quantified. Furthermore, the H2O2 exhibited the capability to undergo direct catalysis by Fe(II), which substantially facilitated the inactivation of pathogenic bacteria. This work unveils insight into the COF-based S-scheme photocatalysts and offers a sustainable approach for environmentally friendly H2O2 production for sterilization purposes.
