In this work, we successfully synthesized a novel composite (HPW@MOF-199/SBA-15C, PMS-15C) in which MOF-199 encapsulated HPW catalyst (named HPW@MOF-199) was confined in SBA-15C, which is the carboxy-functionalized SBA-15. Physicochemical properties of the composites PMS-15C were systemically characterized by N 2 adsorption–desorption isotherms, wide-angle and low-angle XRD, XPS, FT-IR, SEM, and TEM. The results exhibited that HPW@MOF-199 had been successfully synthesized and embedded into the SBA-15C pores by COOH on the surface of SBA-15C. Meanwhile, the composites PMS-15C exhibited high activity and excellent reuse properties in the esterification reaction of acetic acid and ethanol, and no evidence of aggregation, leaching, or inactivation of HPW@MOF-199 during repeated use. The good dispersion of HPW within the MOF-199 cage and the interaction between HPW@MOF-199 and SBA-15C may be responsible for the good catalytic activity as well as the high stability of PMS-15C.

MOF-199@PVDF composite membranes are prepared by blending with different amounts of ultrasonic synthesized MOF-199 nanomaterials for improving the pure water flux (PWF) and achieving better antifouling and antibacterial performance. The membrane morphology, elemental composition, and surface properties are analyzed by various means of characterizations, including scanning electron microscopy, energy-dispersive X-ray spectroscopy, and water contact angle measurements. The performance of the modified membranes is also determined from the perspective of the PWF, bovine serum albumin rejection, as well as antifouling and antibacterial properties. Due to the variation in the viscosity of dope solution, the composite membranes possess remarkably different morphology, and the M5 membrane, which exhibited a sponge-like structure, the largest surface pore size, and the highest porosity, shows the highest PWF, reaching up to 185.05 L/m 2 h. Moreover, with the incorporation of MOF-199 nanocrystals, the antifouling property, together with the antibacterial property, toward both gram-negative bacteria and gram-positive bacteria, based on M5 and M7 membranes, increases dramatically compared with the pristine polyvinylidene fluoride membrane. In addition, the long-term permeation performance and copper leakage of the membrane are investigated. As a result, the composite membrane, M5, shows great potential in real water treatment.

A sustainable one-pot co-condensation strategy was developed for the fabrication of sodium alginate (SA)-silica hybrid carriers (SA-SiO 2 ), via the covalent cross-linking via carboxyl and hydroxyl groups. The SA-SiO 2 matrix was used as a bio-based platform to immobilize Cu 2+ ions via carboxyl coordination, enabling in situ growth of MOF-199 crystals (denoted as MOF-199@xSA-SiO 2 ). FT-IR, XPS, and UV–vis demonstrated the successful cross-linking of SA with SiO 2 , the effective loading of MOF-199 through −COOH in the SA matrix, and the strong interaction between the carrier SA-SiO 2 and MOF-199. Additionally, SEM and N 2 adsorption-desorption analyses showed that the MOF-199@xSA-SiO 2 composites exhibited a spongy pore structure and possessed a typical mesoporous structure. The [email protected] 2 composite exhibited good catalytic activity in the reduction of 4-NP to 4-AP. Under optimal reaction conditions, the K app of the 4-NP reduction reaction was 0.45 min −1 . In contrast, the MOF-199/0.15SA-SiO 2 composite that was prepared using a post-synthesis method achieved a K app of only 0.11 min −1 . The catalyst maintained 98.23 % conversion of 4-NP five cycles, demonstrating good catalytic activity and stability. This study highlights the dual roles of SA as a porous guide and a metal ligand site, providing a green pathway for designing polysaccharide-MOF complexes for efficient environmental catalysis.

Phthalate acid esters (PAEs) are ubiquitous pollutants in food, necessitating accurate detection to ensure food quality and safety. Herein, a novel MOF-199/graphene aerogel composite-derived porous carbon material (MGC) was successfully fabricated and applied as a solid-phase microextraction (SPME) coating for the efficient extraction and enrichment of trace PAEs from condiment. The MGC coating exhibits high enrichment capacity for PAEs, attributed to its hydrophobic carbon skeleton and abundant mesoporous structure. A sensitive analytical method based on headspace SPME coupled with gas chromatography-flame ionization detection was established using the MGC coated fiber. The method achieved a good linear response, low limits of detection (0.005–0.1 μg L −1 ), satisfactory recoveries (71.9 %-122.6 %). The intra-fiber relative standard deviations are between 0.1 % and 7.9 %, and those for inter-fiber are from 4.8 % to 11.2 %. The successful determination of PAEs in soy sauce and monosodium glutamate confirms the feasibility and practicality of the method. This work offers a novel analytical method with exceptional sensitivity and reliability, while also expanding the application of porous carbon in SPME.

Chitosan crosslinked with metal-organic framework (MOF-199)@aminated graphene oxide aerogel (MOF-199@AFGO/CS) were prepared to adsorb formaldehyde and methyl orange. The prepared MOF-199@AFGO/CS aerogel was well characterized via SEM, EDX , FT-IR, XRD and XPS to reveal the microstructure and composition. Besides, the mechanical property and the stability of MOF-199@AFGO/CS aerogel were investigated. The results showed that MOF-199@AFGO/CS aerogel had good stability in water, compression resilience and thermostability . The study on the ability to adsorb formaldehyde gas and methyl orange showed that the adsorption capacity of MOF-199@AFGO/CS aerogel was related to the pore size and the surface functional groups of MOF-199@AFGO/CS aerogel. When the pore size is moderate, as the amino group and MOF-199 on the aerogel increased, the adsorption capacity of formaldehyde gas (197.89 mg/g) and methyl orange (412 mg/g) can reach the maximum. Furthermore, the adsorption process at equilibrium followed the Freundlich isotherm model. The kinetic behavior was well fitted by the pseudo-second-order model, indicating chemisorption as the rate-determining step. This work can provide a reliable basis for the adsorbent to remove pollutants in different forms at the same time, and has potential application in simultaneously adsorbing liquid pollutants and gas pollutants.

Chemodynamic therapy (CDT) efficacy in the tumor microenvironment (TME) remains compromised. Inspired by the potential of fever-like heat to activate a redox-favorable microenvironment, mild photothermal therapy (mPTT) is expected to sensitize tumors to CDT, turning “redox-cold” tumors into “redox-hot” ones. Herein, an injectable gel engine (LMFT@SG-R) is meticulously constructed based on the co-encapsulation of R848 and β-lapachone (LAP)-loaded metal–organic framework-199 (MOF-199) within a lipidic gel reservoir with the unique ability of thermally reversible sol–gel phase transformation. With mPTT reprogramming TME, the custom-designed LMFT@SG-R can realize systemic redox homeostasis remodeling through mPTT-activated chemodynamic immunotherapy (MPCIT). Once reaching the TME, LMFT@SG-R quickly hydrates into solid gel and subsequently undergoes gel-to-sol transformation under mild NIR laser irradiation, resulting in on-demand release of LMFT and R848 for controllable CDT and immunostimulation. LMFT undergoes stepwise degradation for sequential release of Fe 3+ , Cu 2+ and LAP, which can promote ROS cascade amplification owing to the upregulation of HSP70/NQO1 axis upon mild hyperthermia, resulting in robust ICD effects and T lymphocytes infiltrations together with R848. Notably, the controllable immunostimulation can facilitate robust abscopal effects and prominent suppression of distal tumors. The well-designed LMFT@SG-R may represent an updated CDT catalyst with the highly-integrated gel engine for chained-cooperative MPCIT.
