摘要 ：
Warm-season O-3 pollution has been increasingly frequent worldwide in the past few years, exposing a threat to human health as well as the natural environment. Here, the authors showcase a stable MOF which can not only effectively capture various airborne VOCs, but decompose trace O-3 in ambient air. Atmospheric ozone has long been a threat to human health, however, rational design of high-performance O-3-decomposition catalysts remains challenging. Herein, we demonstrate the great potential of a series of isomorphous bimetallic MOFs denoted as PCN-250(Fe2M) (M = Co2+, Ni2+, Mn2+) in catalytic O-3 decomposition. Particularly, PCN-250(Fe2Co) showed 100% O-3 removal efficiency for a continuous air flow containing 1 ppm O-3 over a wide humidity range (0 - 80% RH) at room temperature. Mechanism studies suggested that the high catalytic performance originated from the introduction of open Co(II) sites as well as its porous structure. Additionally, at low pressures around 10 Pa, PCN-250(Fe2Co) exhibited high adsorption capacities (89 - 241 mg g(-1)) for most VOCs, which are not only a class of hazardous air pollutants but also the precursor of O-3. This work opens up a new avenue to develop advanced air purification materials for O-3 and VOCs removal in one.

摘要 ：
Clenbuterol (CLE) and ractopamine (RAC) are two kinds of typical β2-adrenergic agonists which pose a serious threat to the health of human beings. In this work, 10 kinds of metal-organic frameworks (MOFs) with high stability and various pore features are screened to assess adsorption performance for CLE and RAC. An Al(III)-MOF (BUT-19) with abundant ethyl groups exhibits exceptional performance in removing CLE and RAC from water. The maximum adsorption capacity for CLE and RAC are up to 294.1 and 366.3 mg/g under the optimum adsorption conditions, respectively. Meanwhile, the adsorption mechanism effects of pH, temperature, and coexisted ions are investigated systematically. It is found that the MOF pore size and weak hydrogen-bond interactions between CLE/RAC molecules and the MOF are the main causes leading to the extraordinary adsorption. This study provides a new idea for the purposeful design and synthesis of MOFs for removing environmental pollutants and sheds light on the depuration of contaminated water.

摘要 ：
In the past few years, metal-organic frameworks (MOFs) have emerged as a class of fascinating materials for photocatalysis. Herein, a new MOF formulated as [Zn(bpe)(fdc)]center dot 2DMF (BUT-206, bpe = 1,2-bis(4-pyridyl) ethylene, H(2)fdc = 2,5-furan dicarboxylic acid, DMF = N,N-dimethylformamide) is reported, which was synthesized under solvothermal conditions and applied for photocatalytic degradation of dyes (crystal violet and rhodamine B). Noteworthily, BUT-206 exhibited high photocatalytic activity toward the degradation of crystal violet without using any photosensitizer or cocatalyst under UV-irradiation. The photocatalytic degradation of crystal violet by BUT-206 was effective with a degradation efficiency of 92.5% within 120 minutes. The effects of key parameters including pH, amount of photocatalyst and initial concentration of dye on the dye degradation processes were examined, and the kinetics of dye degradation was established by the pseudo-first order kinetic equation. Furthermore, BUT-206 showed good cyclic stability in photocatalytic performance for up to five regeneration cycles, making it a potential green catalyst for dye degradation.

摘要 ：
The pollution of heavy metal ions has long been a big concern to the society. The development and utilization of porous materials for the adsorptive removal of heavy metal ions in water represents one of the hottest research subjects in related areas, such as materials science and environmental science. Due to their structural variety, large specific surface area, adjustable pore size, and tailorable pore surface characteristics, metal-organic frameworks (MOFs) show great potential in many applications, such as gas separation, catalysis, and sensing. In the past few years, many major breakthroughs have been made in the construction of highly stable MOFs. A lot of research works have been explored for the applications of MOFs in water systems, including the adsorptive removal of heavy metal ions in water. Cr(VI) ions are a kind of wide-distributed heavy metal ions with high toxicity, existing in water in various forms under different conditions. The study on the removal of Cr(VI) ions from water is of significance academically and practically. Herein, the published research works about adsorptive removal of Cr(VI) ions with MOFs or MOF-based materials are reviewed. These materials are classified into four classes: (1) highly stable zirconium-based MOF, (2) cationic MOF, (3) post-modified MOF, and (4) MOF-based composite materials. The adsorption mechanism, adsorption capacity, and regenerability of these materials for Cr(VI) ions are also discussed. The existing problems and the trend of future works for the practical application of MOFs in the removal of heavy metal ions are analyzed at last.

摘要 ：
Despite numerous inherent merits of metal-organic frameworks (MOFs), structural fragility has imposed great restrictions on their wider involvement in many applications, such as in catalysis. Herein, a strategy for enhancing stability and enabling functionality in a labile Zr(IV)-MOF has been proposed by in situ porphyrin substitution. A size- and geometry-matched robust linear porphyrin ligand 4,4'-(porphyrin-5,15-diyl)dibenzolate (DCPP2- ) is selected to replace the 4,4'-(1,3,6,8-tetraoxobenzo[lmn][3,8]phenanthroline-2,7(1H,3H,6H,8H)-diyl)dibenzoate (NDIDB2- ) ligand in the synthesis of BUT-109(Zr), affording BUT-110 with varied porphyrin contents. Compared to BUT-109(Zr), the chemical stability of BUT-110 series is greatly improved. Metalloporphyrin incorporation endows BUT-110 MOFs with high catalytic activity in the photoreduction of CO2 , in the absence of photosensitizers. By tuning the metal species and porphyrin contents in BUT-110, the resulting BUT-110-50%-Co is demonstrated to be a good photocatalyst for selective CO2 -to-CO reduction, via balancing the chemical stability, photocatalytic efficiency, and synthetic cost. This work highlights the advantages of in situ ligand substitution for MOF modification, by which uniform distribution and high content of the incoming ligand are accessible in the resulting MOFs. More importantly, it provides a promising approach to convert unstable MOFs, which mainly constitute the vast MOF database but have always been neglected, into robust functional materials.

摘要 ：
A chemically stable Zr(IV)-based metal-organic framework (BUT-17) has been explored for simultaneous adsorption and determination of bisphenol compounds (BPs) in aqueous medium. The prepared BUT-17 possesses a large surface area (2936 m2 g-1) and excellent fluorescent performance. An adsorption capacity of 111 mg g-1 for bisphenol A (BPA) with a rapid adsorption rate (1.76 g mg-1 min-1) is achieved by BUT-17. The excellent adsorption performance could be attributed to the hydrogen bond interaction between BPs and BUT-17. Furthermore, the fluorescent intensity of BUT-17 was quenched up to 92% due to the formation of complexes between BPs and BUT-17. Thus, a BUT-17-based fluorescent sensing method for the rapid determination of BPs has been established with the limit of detection of 10.0 ng mL-1 for BPA and a linear range from 2.0 to 23.0 μg mL-1. These results indicate that as an outstanding multifunctional platform, BUT-17 is promising for the simultaneous removal and determination of BPs in water medium. Simultaneous removal and detection of BPs with BUT-17.

摘要 ：
Enhancing electrocatalytic water splitting performance by modulating the intrinsic electronic structure is of great importance. Here, porous bimetallic oxide and chalcogenide nanosheets grown on carbon paper denoted as NiCo2X4/CP (X = O, S, and Se) are prepared to demonstrate how the anion components affect the electronic structures and thereby disclose the correlation between their intermediates interaction and catalytic activities. The experimental characterization and theoretical calculation demonstrate that Se and S substitution can promote the ratio of Co3+/Co2+ and thereby modulate the electronic structure accompanied with the upshift of d band centers, which not only enhance the inner conductivity but also regulate the interaction between the catalyst surface and intermediates, especially for the adsorption of absorbed H and hydroperoxy intermediates towards respective hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). As a result, a full alkaline electrolyzer using NiCo2Se4/CP and NiCo2S4/CP as cathode and anode delivers a low voltage of 1.51 V at 10 mAcm(-2), which is comparable even superior to most transition metal-based electrolyzers.

摘要 ：
Hydrophobic property of metal-organic frameworks (MOFs) is not only important for their stability improvement but also has a profound effect on the performance of many applications. The essence of coordination bonds led to most of the MOFs are hydrophilic and hydrophobic MOFs are generally achieved by hydrophobic modification of pore surface. Here, we report the systematic regulation of water adsorption and hydrophobic property of a classical MOF MIL-101(Cr) through post-synthetic modification. The contact angle (CA) of modified MIL-101 could vary from 17.9 degrees to 146.5 degrees by changing the alkyl chain length of primary amines. The water adsorption capacity and step pressure can also be tuned correspondingly.
