In this research, we report a simple and cost-effective method for the preparation of two-dimensional (2D) Ni 2 P-Ni(PO 3 ) 2 derived from metal-organic frameworks (MOFs) via a one-step thermal phosphorization strategy. The resulting material is employed to significantly enhance the photocatalytic hydrogen evolution performance of zero-dimensional (0D) CdS nanoparticles. Through an ultrasonic-assisted strategy, the CdS nanoparticles are uniformly dispersed on the surface of Ni 2 P-Ni(PO 3 ) 2 , leading to the successful fabrication of a Ni 2 P-Ni(PO 3 ) 2 /CdS composite with substantially enhanced photocatalytic performance. Under visible light irradiation (λ ≥ 420 nm) using Na 2 S-Na 2 SO 3 as sacrificial agents, the 3 wt% Ni 2 P-Ni(PO 3 ) 2 /CdS composite demonstrated a remarkable photocatalytic hydrogen evolution rate of 2235 µmol g −1 h −1 , which is approximately 7.5 times higher than that of pristine CdS (297 µmol g −1 h −1 ). Over a 20 h cycling experiment, the composite catalyst demonstrated remarkable stability, maintaining around 78 % of its initial hydrogen generation efficiency. The enhanced performance of the composite is ascribed to the role of Ni 2 P-Ni(PO 3 ) 2 in facilitating the separation of photoinduced charge carriers from CdS and improving electrical conductivity. A possible electron-hole transfer mechanism is proposed based on the experimental findings. This work is expected to be helpful in fabricating efficient CdS photocatalysts.

Blood-contacting materials are frequently challenged by endothelial damage, thrombosis, and intimal hyperplasia, significantly limiting their long-term efficacy. To mitigate these issues, a composite coating was developed by integrating nitric oxide (NO)-releasing CuBTTri with hyaluronic acid (HA) on a polydimethylsiloxane surface. To combine the cell adhesion property of polydopamine coatings, the hydrophilic and antifouling properties of HA, and the ability of CuBTTri to catalyze NO release, a polydopamine-polyethylenimine layer was deposited to enhance surface adhesion, followed by the covalent attachment of CuBTTri-loaded hyaluronic acid, forming hyaluronic acid-polydopamine composite coatings (PHMn). Among these, the PHM2 coating (200 μg/mL CuBTTri, obtained by dispersing 1 mg CuBTTri in 5 mL HA solution) demonstrated superior performance, efficiently catalyzing NO release from endogenous donors. This process selectively inhibited smooth muscle cell (HUVSMC) adhesion and proliferation while fostering endothelial cell (HUVEC) growth, achieving a HUVEC-to-HUVSMC density ratio of approximately 1.9. Furthermore, HUVECs on PHM2 exhibited high viability (∼97%) and increased CD31 expression, reflecting favorable endothelialization. The coating also displayed remarkable hemocompatibility, as evidenced by extended plasma recalcification time and a reduced hemolysis rate. The NO-releasing capability of CuBTTri, in conjunction with the hydrophilic and antifouling characteristics of hyaluronic acid, constitutes an effective strategy for fabricating blood-contacting materials with selective endothelialization and sustained hemocompatibility.

Metal-organic frameworks (MOFs) have garnered extensive research interest due to their ultrahigh porosity and flexible tunability. However, the predominantly microporous structures of most reported MOFs impose substantial mass transfer resistance and restrict the exposure of active sites, while their powdered form poses a major bottleneck for industrialization. In this work, hierarchical ultrasmall MOF aerogels with micro/mesoporous structures and high specific surface area, HP-UiO-66-NH2-X@WCA are successfully synthesized via an in-situ construction strategy driven by H2O/Ace competitive nucleation. Notably, the fabricated HP-UiO-66-NH2-X@WCA under this solvent-regulated environment effectively exposes more active sites and promotes the rapid diffusion of large molecules due to its ultrasmall nanoparticles (< 25 nm) and tunable interconnected mesopores (3.7 - 21.3 nm). Moreover, HP-UiO-66-NH2-X@WCA exhibits excellent structural stability and elasticity, imparting exceptional durability and convenient recyclability in practical applications. Benefiting from above advantages, HP-UiO-66-NH2-X@WCA demonstrates superior macromolecular selective adsorption and efficient catalytic activity compared to microporous MOF aerogels with larger particle sizes. Furthermore, when HP-UiO-66-NH2-X@WCA is packed into a fixed-bed reactor for continuous-flow catalysis, it exhibits excellent activity and stability over long-term operation. This work offers new insights into the controlled design and fabrication of high-performance hierarchical MOF aerogels for practical adsorption and catalytic applications.

This study presents a facile synthesis of cerium-based metal–organic frameworks (Ce-BTC) and their subsequent pyrolysis into nanorod-shaped CeO 2 -BTC for interfacial engineering in carbon-based perovskite solar cells (C-PSCs). The optimized FTO/SnO 2 /CH 3 NH 3 PbI 3 /CeO 2 -BTC/Carbon architecture achieves a maximum power conversion efficiency (PCE) of 14.63%, representing a 31.09% enhancement over the baseline device. This improvement stems from multiple synergistic effects: CeO 2 -BTC demonstrates exceptional charge extraction capability, establishes superior interfacial contact, and directly coordinates with perovskite through Pb-O bond formation. Furthermore, the C=O groups effectively anchor uncoordinated Pb 2 + ions, modulating perovskite crystallization kinetics and improving film quality. Subsequent hot-pressing treatment elevates the champion device PCE to 15.12% through enhanced interfacial compactness. Remarkably, the optimized devices retain 93.26% of initial efficiency after 700 h of ambient air exposure without encapsulation, demonstrating exceptional environmental stability. This work provides a comprehensive strategy for developing high-performance, durable carbon-based perovskite photovoltaics through rational interface engineering.

Sulfamethazine is an antibiotic whose anti-degradability and potential for water pollution have become a threat to water contamination. This study designed a composite cathode of Fe-MOF-525/Ti 3 C 2 to effectively remove SMT through Photoelectro-Fenton (PEF). Characterization and photoelectrochemical test results indicate that Fe-MOF-525/Ti 3 C 2 contains abundant active sites and exhibits excellent catalytic performance for the oxygen reduction reaction (ORR). Tests demonstrated that under optimized conditions, the PEF system achieved a removal rate of 95.6% for SMT and a cumulative H 2 O 2 concentration of 53 mM within 120 minutes. Reactive oxygen species (ROS) capture experiments confirmed that •OH and •O 2 − are the main ROS responsible for the degradation of SMT. Further studies investigated the possible degradation pathways. Overall, this work demonstrates an example of pollution control resulting from the philosophy of green chemistry, which offers a promising pathway to reduce the chemical demand for advanced oxidation processes.

Metal-organic frameworks (MOFs), characterized by their high porosity, large specific surface area, and tunable pore structures, have emerged as promising host materials for advanced functional applications. In this study, two organic dyes, fluorescent bleacher (CBS) and coumarin (C6), exhibiting blue and green fluorescence, respectively, were co-encapsulated into europium (Eu)-based MOFs, where Eu3+ served as the central metal to introduce red emission. The ligand employed was 9-butylcarbazole-2-carboxylhydrazide thiophene (Cz). A white fluorescent powder, coumarin/fluorescent bleacher/carbazole derivatives@Eu (C6/CBS/Cz@Eu), was synthesized using an in situ encapsulation method. The C6/CBS/Cz@Eu was incorporated into PVA to prepare a film. The resulting C6/CBS/Cz@Eu film demonstrated a high-quality white light emission under excitation by commercial 400 nm light-emitting diode (LED) chips, achieving ideal Commission Internationale de l'Éclairage (CIE) chromaticity coordinates of (0.34, 0.35) and a correlated color temperature (CCT) of 5267 K. This strategy offers a versatile and scalable method for the design and fabrication of white light-emitting materials, beneficial for the development of next-generation white light-emitting diode (WLED) technologies.

High-performance electrode materials are critical for the development of the capacitive deionization (CDI) technology for efficient water desalination. In this study, binder-free porous carbon electrodes were successfully prepared from the fungal hyphae sheet with the formation and growth of metal-organic framework (MOF) crystals on the surface of hyphal fibers. The continuous fungal fibrous structure with abundant surface functional groups provided an ideal supporting substrate for in-situ oriented MOF growth. The MOF-fungal hyphae derived carbon (MOF-Fhy-C) exhibited an excellent property for CDI application, such as a large accessible surface area, excellent electrical conductivity, high porosity and hydrophilicity. The MOF-Fhy-C electrode achieved an outstanding CDI performance with a salt adsorption capacity of 40.8 mg/g and an average salt adsorption rate of 1.4 mg/(g·min) for treating 10 mmol/L NaCl solution at a cell voltage of 1.2 V, which are considerably higher than most of carbon-based electrodes reported in the literature. This research presents an effective strategy for fabricating freestanding CDI electrodes from fungal materials with MOF for high-performance desalination.

Metal-organic framework (MOF-5) material was synthesized by solvothermal method. Porous carbon (C) and sulfur-doped porous carbon (S/C) were fabricated by calcining and vulcanization of MOF-5. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and Raman spectroscopy were used to characterize the crystal structure and morphology of the samples. The electrochemical performance of C and S/C materials were tested as anode materials for lithium ion batteries (LIBs) and sodium ion batteries (SIBs). The S/C exhibits the high reversible capacity (1114.8 mAh g −1 after 100 cycles at 0.1 A g −1 and 485 mAh g −1 after 500 cycles at 2.0 A g −1 ), as anode for LIBs. It behaves a reversible discharge capacity of 268.8 mAh g −1 after 100 cycles at 0.1 A g −1 and a capacity of 157 mAh g −1 after 1000 cycles at 2.0 A g −1 , as anode for SIBs. Compared with C, the electrochamical performance of S/C material is significantly improved. This is mainly because the bigger specific surface area and the doping of sulfur atoms increases the layer spacing and facilitates the kinetics of the intercalation and deintercalation of Li + and Na + ions, especially Na + ions.

Separation of CH 4 from natural gas is an essential but extremely challenging process in the petrochemical industry. Here, we tailored a MOF-based adsorbent with partitioned aliphatic pore spaces through the simultaneous incorporation of the aliphatic sites and the symmetrically matched partition agent. The resulting adsorbent demonstrates exceptional adsorption capacity for C 3 H 8 and C 2 H 6 compared to CH 4 , along with remarkably competitive adsorption selectivities for C 3 H 8 /CH 4 and C 2 H 6 /CH 4 . Breakthrough experiments further support the excellent dynamic separation efficiency of the adsorbent for the purification of CH 4 from natural gas. Moreover, detailed density functional theory calculations and molecular simulations elucidate the synergistic interactions between the aliphatic sites and the partitioned pore spaces within the adsorbent, which promote the stronger binding affinities for C 3 H 8 and C 2 H 6 over CH 4 .

In this study, we develop a filter paper-supported Ag nanowire (AgNWs) substrate coated with a tunable layer of zeolitic imidazolate framework-67 (ZIF-67) metal-organic framework (MOF) for surface-enhanced Raman scattering (SERS) applications. The thickness of the ZIF-67 layer is precisely controlled by adjusting the soaking time, allowing us to investigate the influence of MOF thickness on SERS performance using probes with different sizes. Sensitivity for large, impenetrable molecules such as thiram and rhodamine 6G (R6G) are primarily governed by localized surface plasmon resonance (LSPR), while smaller, penetrable molecules like 4-mercaptobenzoic acid (4-MBA) exhibit enhanced sensitivity driven by charge transfer (CT) effects due to their ability to penetrate the MOF layer. A finite-difference time-domain (FDTD) simulation reveals that the porous structure of ZIF-67 facilitates electric field propagation to the probe, maintaining significant LSPR effects even beyond 200 nm from the AgNWs. Practical applicability is demonstrated using a wiping mode to detect thiram spiked on apple surfaces, with reliable linear detection achieved across a wide range of concentrations. This study underscores the potential of MOF-based hybrid SERS substrates for real-world applications, leveraging the complementary roles of CT and electromagnetic (EM) mechanisms to enhance sensitivity.

With the extensive use of neonicotinoid pesticides like thiamethoxam (TMX), there is a growing need to develop sensitive and selective methods to monitor its residue levels. In this study, we developed a fluorescence sensor based on terbium/cerium metal-organic framework combined with molecularly imprinted polymer (Tb/Ce MOF@MIP) for TMX detection. Through systematic optimization of synthesis conditions and detection conditions, the sensor was successfully employed for the determination of TMX, exhibiting high selectivity, along with a linear detection range of 1–50 μM and a limit of detection of 0.8 μM. In addition, the practical applicability of the sensor was validated in real samples including apples, tea, and soil, and the accuracy was assessed through recovery experiments.

The widespread use of fluoroquinolone antibiotics (FQs) in medical and agricultural applications has raised significant environmental and food safety concerns, necessitating the development of sensitive and reliable detection methods. This study presents an advanced analytical approach combining a novel hierarchical magnetic Metal organic framework@Covalent organic framework (MOF@COF) composite materials, named Fe 3 O 4 @NH₂-MIL-88(Fe)@TpBD (Fe 3 O 4 @MOF@COFs), with high-performance liquid chromatography-ultraviolet detection (HPLC-UV) for trace-level FQ determination. The composite was synthesized via a solvothermal method featuring in situ growth of covalent organic frameworks (COFs) on magnetic metal‒organic frameworks (MOFs) and exhibited exceptional performance in magnetic solid‒phase extraction (MSPE) of three target FQs (enrofloxacin, ciprofloxacin, and norfloxacin). The method achieved outstanding sensitivity (0.23–0.27 ng mL⁻¹), a wide linear range (0.70–1000 ng mL⁻¹), strong correlation (R² = 0.9996), and excellent repeatability (1.6–3.8 % RSD). Successful applications in tap water and chicken samples demonstrated recoveries of 85.8–112.2 %, whereas adsorption studies using pseudo-first-order, pseudo-second-order, Langmuir, and Freundlich models provided mechanistic insights into the extraction process. This work has the following advantages: (1) a graded magnetic adsorbent with good extraction efficiency was designed through the synergistic effect of MOF-COF, (2) a robust detection scheme with convenient and fast performance was established, and (3) the adsorption mechanism of recyclable materials was elucidated, thereby demonstrating excellent practical utilization. In summary, this MOF@COFs-MSPE-HPLC-UV method provides a sensitive, efficient, and sustainable solution for monitoring trace FQ pollutants in complex matrices, which is expected to promote the development of the environment and food safety.
