The integration of microscopic material designs and macroscopic structural layouts offers unlimited potential for developing advanced electromagnetic wave (EMW) absorbers. Herein, a pyrolysis-based strategy is reported for the hybridization of Ti 3 C 2 T x MXene nanosheets to achieve relaxation processes and high-density magnetic coupling at the nanoscale. The stratified structure of Ti 3 C 2 T x /Fe-MOF considerably amplifies the active contact region with electromagnetic radiation, thereby inducing numerous reflection/scattering phenomena. Through pyrolytic transformation, derived nanoparticles including Fe, C, Fe 3 O 4 , and TiO 2 establish continuous metal–carbon and carbon-oxide interfaces below 50 nm. Consequently, the heterogeneous interfaces formed between these components establish a harmonious electromagnetic coupling network, where interfacial polarization from numerous heterojunctions promotes charge accumulation and relaxation processes, converting electromagnetic energy into thermal energy. Remarkably, findings indicate that this composite material demonstrates a minimum reflection loss (RL min ) of −47.05 dB when the thickness reaches 1.8 mm. Additionally, this investigation broadens the spectrum of design strategies for premium microwave absorption materials through systematic interface engineering and thermally-controlled phase conversion.

A novel B,N-decorated carbocatalyst (Fe@BPC-XBN) for peroxymonosulfate (PMS) activation was prepared by a simple pyrolysis method using the iron-based metal organic frameworks (Fe-MOF), boric acid and boron nitride (BN) as precursors. Fe@BPC-20BN removed 93.3% of bisphenol A (BPA) in 90 min compared to 64.9%, 82.1% and 83.5% with Fe@PC, Fe@BPC and Fe@PC-20BN, respectively, with 0.15 g/L catalyst and 1 mM PMS at initial pH of 7. The solo B-doping with boron acid on the Fe-MOF derived porous carbon enhanced its catalytic capacity; moreover, B, N co-doping with BN and boron acid as precursors further promoted the catalytic performance. The addition of BN not only provided more B, N catalytic centers but also improved the stability of the carbocatalyst. In addition, hydroxyl radicals , sulfate radicals, superoxide radicals, and singlet oxygen species were involved in the degradation of BPA. Fe species, –BCO 2 /–BC 2 O, pyridinic N, and pyrrolic N groups on the carbon matrix played the important roles in the BPA degradation. The outstanding catalytic performance of Fe@BPC-20BN could be attributed to the synergistic effects between iron nanoparticles and the B/N codoped carbon matrix. This study gives new insights into the design and preparation of high-efficient B,N-decorated carbocatalysts for environmental remediation.

It is of great significance for electrochemical sensors to simultaneously detect dopamine (DA) and uric acid (UA) related to biological metabolism. In this work, two-dimensional (2D) porous carbon nanosheets (CNS) was prepared as electrocatalysts to improve the sensitivity, the selectivity, and the detection limit of the simultaneous detection. First, 2D amorphous iron-metal organic frameworks (Fe-MOF) was synthesized with Fe3+ and terephthalic acid via a facile wet chemistry method at room temperature. And then, CNS was prepared by pyrolysis and pickling of Fe-MOF. CNS had large specific surface area, good electrical conductivity and lots of carbon defects. The response currents of the CNS modified electrode was larger than those of the control electrodes in the simultaneous determination. The simultaneous determination was measured via differential pulse voltammetry to reduce the effect of capacitive currents on quantitative analysis. The CNS modified electrodes showed high sensitivity and low detection limit for the simultaneous detection of DA and UA. The modified electrodes have been successfully used to detect DA and UA in normal human serum.

In this study, a rapid, low-cost and facile method for detecting exosomes was developed by engineering DNA ligands on the surface of an iron-based metal–organic framework (Fe-MOF). Aptamers of exosomal transmembrane CD63 protein (CD63-aptamers) were utilized as both the optically active layer and the exosome-specific recognition element to engineer an Fe-MOF bio-interface for high-efficiency regulation of the catalytic behavior of Fe-MOF toward the chromogenic substrate. The effective enhancement of the intrinsic peroxidase-like catalytic activity was confirmed via the self-assembly of CD63-aptamers on the surface of Fe-MOF. The specific binding of exosomes with CD63-aptamers altered the conformation of DNA ligands on the surface of Fe-MOF, contributing to sensitive variation in Fe-MOF catalytic activity. This directly produced a distinct color change and enabled the visual detection of exosomes. Via one-step “mixing-and-detection”, the Fe-MOF bio-interface exhibited excellent performance in quantitative analysis of exosomes derived from human breast cancer cell lines ranging from 1.1 × 10 5 to 2.2 × 10 7 particles/μL with a detection limit of 5.2 × 10 4 particles/μL. The expression of exosomal CD63 proteins originated from three types of cancer cell lines, including breast cancer, gastric cancer and lung cancer cell lines, was differentiated within only 17 min. Furthermore, the method was successfully applied to the identification of exosomes in serum samples, suggesting its potential in clinical analysis as a valuable tool for the rapid, convenient and economical testing of exosomes.

Ferroptosis has drawn great attention to tumor treatments over the past decade. However, how to specifically boost tumoral redox imbalance by simultaneously superimposing iron-mediated reactive oxygen species and undermining antioxidative pathways at the tumor site is still a significant challenge in ferroptosis-based tumor ferrotherapy. In this study, we designed an in situ generable hydrogel that contains paclitaxel/chlorin e6-loaded iron-based metal-organic framework (Fe-MOF) nanoparticles for enhanced breast tumor ferrotherapy by multiplex magnifying redox imbalance. The polysaccharide sodium alginate can crosslink with tumoral calcium ions to generate a hydrogel patch, which promotes the retention of Fe-MOF and therapeutic molecules. The Fe-MOF holds peroxidase/glutathione oxidase mimicking properties, resulting in OH generation via the Fenton reaction and glutathione consumption. Local ultrasound treatment facilitates the release of therapeutics and stimulates the generation of signet oxygen by activating the sonosensitizer chlorin e6. In the meanwhile, the low-dose paclitaxel reduces tumoral pH value by downregulating the glutaminolysis-related gene (SLC7A11) which in turn enhances the catalytic activity of Fe-MOF and inhibits antioxidative pathways, respectively. Both in vivo and in vitro experiments show that our designed hybrid hydrogels can induce significant ferrotherapeutic effects by augmenting the tumoral oxidative stresses .

Photocatalytic oxidation of aromatic alcohol into aromatic aldehyde using O 2 has received huge attention, while the reaction that occurred in ambient air is rarely studied but follows the green-chemistry principles. Herein, spindle-shaped MIL-53(Fe)-NH 2 @ZnIn 2 S 4 photocatalysts with a Z-scheme heterostructure were facilely developed for photocatalytic oxidation of aromatic alcohol in air under visible light. The benzyl alcohol conversion can be notably enhanced to 73% over the optimal MIL-53-NH 2 @ZnIn 2 S 4 sample with a benzaldehyde production rate of 1825 μmol g –1 h –1 . However, in the O 2 atmosphere, the benzyl alcohol conversion is only 56%, indicating that O 2 is not required and has an adverse effect on the reaction. The hierarchical structure and Z-scheme heterojunction of MIL-53-NH 2 @ZnIn 2 S 4 impart an efficient separation and strong redox abilities of photo-induced electrons and holes, which are responsible for the impressive photocatalytic performance. This study could motivate the ingenious design of Z-scheme heterostructures for green organic conversion based on MOFs.

The efficient resource utilization of inorganic solid waste steel slag is greatly desired. However, its global utilization rate remains low, underscoring the urgent need for novel and effective processing routes. In this paper, Fe-MOF was successfully synthesized using steel slag as the raw material, which was inserted into the layers of the two-dimensional material MXene to achieve a composite structure, which was then deposited onto a superhydrophilic fiber cloth made from recycled waste cotton pads. The resultant composite material exhibited superior and stable superhydrophilic and underwater superoleophobic properties through complex intermolecular forces of glycyrrhizic acid (GA)-based ligand compounds. The highly hydrophilic GA formed gel-like protecting layer, which strongly maintained the stable superhydrophilic layer of the composite. The introduction of Fe-MOF enhanced the interlayer spacing of MXene and formed heterojunctions at the interface, greatly improving electron transport between the two semiconductors and significantly promoting the photothermal response speed and intensity of the system. Under photothermal action, this composite material can be used for quick separation of viscous oil/water mixtures and emulsion systems, demonstrating excellent oil pollution resistance and cycled usage rate. This composite textile also achieved flame-retardant properties. This paper not only reported a new oil/water separation material but also provided a new pathway for the high-value utilization of steel slag and the recycling of waste cotton pads.

The conversion of waste plastics into metal-organic framework (MOF) photothermal materials presents promising opportunities for solar energy conversion, facilitating freshwater production and water purification through interfacial solar evaporation, and simultaneously heralding advancements in plastic waste recycling. Herein, we present a bimetallic Co/Fe-MOF photothermal converting material derived from PBAT-based plastic wastes, tailored for efficient solar water evaporation. The nanosheet-structured bimetallic Co/Fe-MOF featuring high light absorption, water wettability and photothermal conversion efficiency delivers an optimal evaporation rate of 1.81 kg m −2 h −1 under one sun irradiation, surpassing that of monometallic MOFs. Moreover, we employed three substrates—nanofiber film, aerogel, and hydrogel—to immobilize the Co/Fe-MOF solar absorbers, thereby constructing monolithic hybrid solar evaporators. These substrates not only confer the flexibility to Co/Fe-MOF solar absorbers for practicability but also serve as mediates to regulate thermal management and water states. Consequently, the hybrid evaporators exhibited significantly enhanced evaporation rates, with the hydrogel evaporator achieving to ~3.53 kg m −2 h −1 , coupled with remarkable salt resistance and durability. This bimetallic Co/Fe-MOF-based solar evaporator efficiently serves a dual purpose, enhancing clean water production through solar desalination and purification while also presenting a viable alternative to the issue of plastic waste, potentially harmonizing energy, environment and clean water nexus.

Eliminating various organic pollutants from wastewater continues to pose a major environmental issue. Herein, CO 2 -responsive magnetic bio-aerogels (Ag/Fe-NC@DCG) integrating “smart” adsorption and photo-Fenton-like degradation were constructed by embedding surface plasmon resonance (SPR)-enhanced MOF-derived Ag/Fe nanocarbon (Ag/Fe-NC) into cellulose nanocrystal reinforced gelatin aerogels, followed by surface functionalization with a CO₂-responsive silane coupling agent ( N, N -diethyl-3-aminopropyltrimethoxysilane). The resulting aerogels exhibited outstanding adsorption capacities toward charged pollutants, reaching 859.62 mg/g for negatively charged methyl orange (MO) and 635.92 mg/g for positively charged methylene blue (MEB), governed by electrostatic interactions and hydrogen bonding. The adsorption process was well described by the Langmuir adsorption isotherm model and pseudo-second-order adsorption kinetic model. Remarkably, CO 2 served as a trigger gas to enable rapid and selective adsorption of negatively charged organic pollutants from the mixture, thereby realizing CO 2 -regulated selective adsorption. As anticipated, under visible light irradiation in the presence of peroxymonosulfate (PMS), the Ag/Fe-NC component efficiently catalyzed photo-Fenton-like reactions, leading to significantly enhancing removal efficiencies for both charged and neutral organic pollutants. For neutral bisphenol A (BPA) and amphoteric tetracycline hydrochloride (TCH) that were initially unadsorbed, their removal efficiencies rose dramatically from 5.24% and 12.79% to 90.67% and 97.40%, respectively. Additionally, the aerogels demonstrated excellent recyclability, mechanical robustness, and antibacterial activity. Overall, this work presents a versatile and sustainable aerogel platform that integrates CO 2 -triggered selective adsorption with photo-Fenton-like degradation, offering a prospective pathway for wastewater remediation.

Metal–organic frameworks (MOFs) have attracted much interest in electrocatalysis as promising catalysts in recent years. However, it still remains a challenge to directly use MOF-based materials as bifunctional electrocatalysts for overall water splitting. Herein, a hierarchical Co,Fe-MOF-74/Co/carbon cloth (CC) three-layer hybrid electrode is synthesized by a simple electrochemical deposition technology with subsequent solvothermal treatment. Electrochemical performance investigations show that the as-constructed Co,Fe-MOF-74/Co/CC electrode exhibits impressive electrocatalytic activity for full water splitting, which only requires a low overpotential of 226 mV@20 mA cm–2 for the oxygen evolution reaction (OER) and 94 mV@–10 mA cm–2 for the hydrogen evolution reaction (HER), respectively. Employing the as-constructed electrode as the anode and cathode in a two-electrode setup simultaneously, only 1.65 V of the voltage is needed to deliver the current density of 20 mA cm–2. The above excellent electrochemical performances should be attributed to the specific architecture, the synergistic effect of the Co and Fe species, and the superhydrophilic surface of the catalyst. More importantly, further investigations uncover that metal hydroxides and oxyhydroxides produced in situ during electrochemical tests are the veritable active species, which promote the high catalytic activity of the present catalyst.

Single-atom metal-anchored porphyrin-based metal–organic frameworks (MOFs) have shown excellent light absorption, catalytic sites, and high stability during photocatalytic reactions, while there are still challenges for facile assembly with quantum dots to enhance catalytic dynamics. Herein, a kind of Fe single atom-doped MOF material (Fe-MOF-525) was ball milled with CdS in a proper ratio through Fe–N4 and Fe–N–C bonding, which showed the enhanced photoinduced carrier separation ability. As a result, extended light absorption ranges of CdS/Fe-MOF-5252.3 induced the promotion of the photocatalytic hydrogen (H2) value (3638.6 μmol g–1 h–1), which was 7.2 and 2.3 times higher than those of Fe-MOF-525 and CdS. In this work, the facile synthetic technique, specific active sites, and enhanced catalytic dynamics in the composite highlight the future research on MOF-based heterojunctions and their potential photocatalysis applications..

Luteolin is a potent anti-colorectal cancer chemical. However, its effectiveness is hindered by its poor solubility in water and fat, and it is easy to degrade by gastrointestinal enzymes. In this study, a nano-composite carrier, NH 2 -MIL-101(Fe)@GO (MG), based on aminated MIL-101(Fe) and graphene oxide (GO) was developed and evaluated. This carrier co-delivered luteolin and matrine, while marine was used to balance the pH for the nano-preparation. The loading capacities for luteolin and matrine were approximately 9.8% and 14.1%, respectively. Luteolin's release at pH = 5 was significantly higher than at pH = 7.4, indicating it had an acidic pH response release characteristic. Compared to MOF and GO alone, MG and NH2-MIL-101(Fe)@GO@Drugs (MGD) enhanced anti-cancer activity by inhibiting tumor cell migration, increasing ROS generation, and upregulating the expression of Caspase-3 and Caspase-9. In conclusion, this study contributes new ideas and methods to the treatment strategy of multi-component anti-colorectal cancer therapy. It also advances drug delivery systems and supports the development of more effective and targeted treatment approaches for colorectal cancer.
