Cancer treatment techniques often struggle to simultaneously address the issues of significant impact from cancer heterogeneity, poor resistance to drugs, and non-selective drug toxicity. Therefore, cancer treatment strategies based on nanoplatforms with multiple responsive properties have attracted wide attention due to their broad applicability and minimal side effects on normal cells. Herein, we constructed a nano iron-based metal–organic framework loading Pt and coated with polydopamine (Fe-MOF-NH 2 @Pt@PDA) using the solvothermal method for multimodal cancer therapy. The Pt and Fe could leverage the unique weak acidity and overexpression of hydrogen peroxide in the tumor cell to generate reactive oxygen species (ROS) for chemodynamic therapy (CDT). Additionally, Pt and Fe gave its peroxidase-like activity to produce oxygen, improving the hypoxic environment in the tumor microenvironment. Due to Pt, Fe-MOF-NH 2 @Pt@PDA achieved excellent sonodynamic therapy (SDT) under ultrasound (US) stimulation. Under US, more ROS were generated, enhancing the anticancer effect of CDT. Moreover, Fe-MOF-NH 2 @Pt@PDA produced an excellent photothermal effect under 808 nm near-infrared (NIR) irradiation for photothermal therapy (PTT). Furthermore, Fe-MOF-NH 2 @Pt@PDA exhibited good biocompatibility. Taken together, the nano Fe-MOF-NH 2 @Pt@PDA with synergistic CDT, SDT, and PTT combined treatment was a promising biomaterial for non-invasive clinical cancer therapy.

A novel catalyst with a metal sulfide/hydroxide heterostructure was prepared by introducing sulfur ions into NiMnFe layered hydroxide by a simple hydrothermal method, using a series of characterization methods and electrochemical tests to explore the optimal sulfur ion doping amount. The XPS results show that the introduction of sulfur ions leads to a change in metal electron delocalization, which is conducive to the OER procedure. The newly formed metal sulfide can not only improve the conductivity of NiMnFe LDH/NF electrode materials but also enhance the intrinsic catalytic activity of the materials. The electrochemical performance indicated that the S2-NiMnFe LDH/NF catalyst required only 205 mV overpotential to provide a current density of 10 mA−2, and the Tafel slope was only 45.79 mV dec−1. In addition, the large turnover frequency value (1.2614 S−1) reflects the excellent intrinsic activity of the novel catalytic material.

A Fe/Co-doped zeolitic imidazolate framework-8 (ZIF-8) is synthesized in situ on porous carbonized wood, and high-performance composite electrodes are subsequently prepared through heat treatment. The simultaneous doping of Fe and Co can synergistically modulate the microstructures, nanoporous architectures, and hydrophilic properties of the carbon materials derived from metal-organic frameworks (MOFs), thereby enhancing their specific capacitance and energy density. Furthermore, the superior capacitive performance of Fe/Co-doped MOF-derived carbon on porous carbonized wood (Fe-Co/MC@PCW) is predicted through first-principles density functional theory calculations, which are based on the detailed analysis of band structure and surface adsorption characteristics. The composite electrode demonstrated a specific capacitance of 342 F g −1 (6.84 F cm −2 ) at 5 mA cm −2 . Correspondingly, a symmetric supercapacitor fabricated with this electrode achieved a specific capacitance of 141 F g −1 (2.82 F cm −2 ) under identical conditions, yielding an energy density of 19.58 Wh kg −1 and a power density of 125 W kg −1 . Notably, the electrode maintains exceptional capacitance retention, demonstrating only a minor reduction to 96 % after 15,000 cycles, even at 30 mA cm −2 . These results underscore the potential of integrating MOFs with wood-based carbon electrodes for the development of advanced energy storage systems.

Semiconductor oxides are ideal candidates for future electromagnetic wave absorption and thermal management due to their hole-conducting properties. However, in practical applications, due to its limited conductivity, its development and application in the field of electromagnetic wave absorption and thermal management are greatly limited. The CuAl 1-x Fe x O 2 ceramics were synthesized using the high-temperature solid-phase method to study their microwave absorption and infrared emissivity characteristics. The introduction of Fe significantly improves the electromagnetic wave absorption and emissivity characteristics of CuAlO 2 ceramics. The effects of Fe doping on the dielectric constant, permeability, microstructure, and surface morphology of the composite were systematically analyzed. The results show that Fe doping leads to lattice distortion and the introduction of defects, which effectively improves the conductivity and polarization loss of the material, thus enhancing the dielectric loss and magnetic loss mechanisms of the material and obtaining excellent microwave absorption performance. The results show that when the doping amount of Fe is 3 %, the minimum reflection loss RLmin can reach −50.41 dB, and the effective absorption bandwidth EAB is 4.2 GHz. When the doping amount of Fe is 9 %, the infrared emissivity reaches a peak of 0.936. The porous structure further enhances the absorption and radiation properties of CuAl 1-x Fe x O 2 ceramics. It is further indicated that CuAl 1-x Fe x O 2 ceramics have great application potential in electromagnetic wave absorption and thermal management.

Transition metal single atom catalysts (SACs) for boosting peroxymonosulfate (PMS) activation involving complex catalytic mechanism and multiple reaction pathways have received much attention, but regulating the reaction pathway of SACs is still an important challenge in the PMS-mediated Fenton-like reaction. Herein, a boron-doped Fe SAC with FeN 3 B configurations (Fe—BNC) was synthesized and selectively generated a non-radical pathway, in which the high-valent iron-oxo species (Fe IV O) were determined as the main reactive oxygen species (ROS) by PMS activation. The Fe-BNC/PMS system not only exhibited remarkable reaction kinetic constant (0.949 min −1 ) and turnover frequency (9.49 L min −1 g −1 ) for the phenol degradation, but also showed excellent selectivity to phenols with strong electron-donating ability. Mechanism exploration based on theoretical calculations revealed that high activity of Fe-BNC originated from the reinforced adsorption energy and enhanced overlap between Fe 3d and O 2p orbits, which facilitated to strengthen the Fe-O bonding and accelerate the electron transfer, thus modulating the PMS activation via a non-radical pathway. Successful extendibility of Fe-BNC in treatment of the real water and coking wastewater demonstrates its application potential. This work elucidates the mechanism of selectively generating a non-radical pathway over B-doped Fe-based SAC, and provides a rational strategy for preparing SACs alone with a non-radical pathway.

The escalating global demand for lithium, driven by the green energy transition, necessitates efficient lithium extraction strategies from salt-lake brine and seawater. This study introduces a porous LiFexMn2–xO4 hollow nanofibers (LFMO-h), synthesized by electrospinning and calcination. This material features a well-defined one-dimensional (1D) hollow architecture composed of interconnected spinel nanocrystals (∼80 nm), which establishes ultrashort ion diffusion pathways and abundant active surfaces, enabling ultrafast Li+ transport and rapid adsorption kinetics. The ion diffusion coefficient of LFMO-h is as high as ∼6.6 × 10–10 cm2 s–1, ten times faster than bulky LMO (LMO-s). As a cathode in a hybrid capacitive deionization system, LFMO-h achieves a high Li+ adsorption capacity of ∼1.4 mmol g–1 with an energy consumption of ∼4.7 Wh mol–1. Remarkably, LFMO-h presents a super Mg2+/Li+ selectivity (αMg2+Li+ = 180 at CMg2+/CLi+ = 60), while maintaining structural integrity and negligible Mn dissolution during prolonged cycling, attributed to synergistic Fe-doping and dense arrangement of nanocrystals. Even in the simulated high Mg2+ salt-lake brine, LFMO-h retains its high adsorption capacity and selectivity, demonstrating robustness under practical conditions. This work pioneers an accelerated diffusion-adsorption strategy through 1D hollow nanofiber engineering for energy-efficient lithium recovery technologies.

Ga exhibits enrichment in coal-based solid waste, establishing it as a promising alternative source for Ga recovery. The HNO 3 pressure leaching process effectively achieves simultaneous leaching of Al and Ga while retaining most of the Fe in the residue. However, separating Ga from acidic solutions containing Fe and Al remains a persistent challenge in hydrometallurgy due to their similar physicochemical properties. Herein, a simplified and effective two-stage sequential solvent extraction process using acid phosphorus extractants (P507 and P204) for selective Ga recovery was proposed. Under optimized conditions, P507 removed 97.2 % of Fe from coal gangue HNO 3 leach liquor with limited co-extraction of Ga (10.1 %) and Al (5.7 %). Subsequent P204 extraction recovered 99.2 % Ga with only 9.1 % Al co-extraction from the Fe raffinate. Stripping with 2 mol·L –1 H 2 SO 4 yielded 88.0 % Ga recovery, with the extractants showing excellent regeneration and cycling performance. Mechanistic studies including FT-IR, UV-Vis, ESI-MS, and stoichiometric analysis confirmed coordination through both P = O and P–O–H groups, forming Fe(HA)A 3 and Ga(HL)L 3 complexes (A = P507; L = P204 ligands), respectively. This study presents a highly efficient approach for the separation of Fe/Ga/Al and Ga recovery from HNO 3 leach liquor, featuring exceptionally low acid depletion.

Microplastic accumulation in water bodies is posing a serious threat to public health. Their chemical inertness impairs the effectiveness of current micro/nano-material-based remediation strategies. Especially in urban drinking water systems, microplastics constantly released and accumulated together with the complexity of pipeline networks challenges the recyclability and long-term stability of remediation materials and technology. To address this, Cu-single-atom magnetic Janus microparticles (CuMJMs) with flower-like crown morphology are engineered meticulously via a step-by-step strategy involving solvothermal growth and chemical deposition. The resulting CuMJMs feature a distinct Janus architecture composed of BiOI nanosheets and Fe 3 O 4 nanoparticles, thereby delivering synergistic magnetic and photocatalytic functionalities. When subjected to a rotating magnetic field, CuMJMs are able to locomote collectively and recover rapidly in confined microenvironments. The incorporation of atomically dispersed Cu single atom not only enhances the number of active sites, but also promotes the separation and migration of photogenerated charge carriers. Such abilities enable CuMJMs to degrade polyethylene (PE) efficiently, achieving a weight loss rate of 53.7 % beyond previous reports. This performance improvement is ascribed to singlet oxygen generation boosted by the Cu single atoms to facilitate oxidative degradation pathways, as supported by electron paramagnetic resonance and active species trapping test. While used in real water matrices, CuMJMs maintain both catalytic activity and magnetic responsiveness, underscoring their robustness and practical potential. This work establishes a new paradigm to active microplastic remediation, merging atomic-level catalytic precision with collective particle behavior to enable scalable and efficient environmental cleanup.

Phenolic acids have a positive effect on the processing quality of myofibrillar protein (MP) gels. However, in this study, the addition of ferulic acid (FA) did not have a positive effect on MP gels. To address this issue, we performed the addition and observed the effects on the structure of MP gels by both surface coating and internal cross-linking: addition of FA alone, addition of α-cyclodextrin (CD) to encapsulate FA (MP-FA/CD), and addition of Fe(III) to form a metal–phenolic network structure (Fe @MP-FA) and a metal–cyclodextrin–phenolic acid structure (Fe@MP-FA /CD). It was found that both Fe @MP-FA formed by surface coating and internal cross-linking were able to improve the textural properties of MP gels, including hardness, elasticity, chewability, adhesion, etc. FA effectively promoted the conversion of some of the non-fluidizable water to the bound water morphology, and the addition of Fe(III) effectively enhanced this trend. In particular, the composite network structure formed by Fe@MP-FA/CD more significantly promoted the conversion to bound water and improved the water retention of the gel. Hydrophobic interactions and hydrogen bonding in non-covalent bonding as well as disulfide bonding in covalent bonding were always the main factors promoting the formation of gels from MP after different additions. Meanwhile, different gel treatments lead to changes in the structure of different proteins. Internal cross-linking with the addition of FA promotes protein oxidation, whereas CD reduces the occurrence of oxidation and promotes a homogeneous gel structure. Surface coating with the addition of FA/CD resulted in a reduction in pores in the MP gels and a denser gel structure. However, the addition of internal cross-linking resulted in a gel with a loose and rough network structure. In this study, we compared the common methods of gel enhancement, with the objective of providing a reference for the improvement in the gel texture of meat products.

The conventional Fenton process generates large amounts of Fenton sludge during wastewater treatment. Achieving effective utilization of Fenton sludge and reducing its production remain pivotal challenges. In this study, Fenton sludge biochar catalysts (Cat) were prepared using Fenton sludge via pyrolysis. In addition, chemical oxygen demand (COD) from secondary effluent was removed by Fenton sludge biochar catalysts activated with H2O2/Fe(VI). Specifically, the removal efficiency of COD could reach 46.2% in the Cat−2/H2O2/Fe(VI) system under weakly alkaline conditions. The mechanistic analysis confirmed that high-valent iron,•OH, O2•−, and1O2all participate in the degradation process. Furthermore, a continuous-flow reactor was applied to treat secondary effluent, with COD decreasing from 65 mg/L to 36 mg/L. This study provides new insights into the resource utilization of Fenton sludge and the treatment of complex wastewater.

Integrated CO2 capture and conversion (ICCC), which simultaneously achieves CO2 enrichment and in situ conversion, represents a promising strategy for reducing CO2 emissions. Dual-function materials (DFMs) that exhibit stable and highly efficient adsorption and catalytic conversion properties are essential to the success of this strategy. In this study, we developed novel Mo/Fe-doped CaO-based DFMs for the integrated CO2 capture and reverse water–gas shift (ICCC–RWGS) process. The synthesized DFMs was evaluated through adsorption–conversion cyclic experiments in a fixed-bed reactor, complemented by X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET), scanning electron microscopy (SEM) mapping, and X-ray photoelectron spectroscopy (XPS) characterizations. The results indicate that the generated composites with a specialized structure not only provide stable support for CaO but also regulate the RWGS process. Specifically, the formation of Ca2Fe2O5 facilitates the hydrogenation of CaCO3 via redox reactions, while the generation of CaMoO4 and Ca2FeMoO6 alleviates both the volume-change effects of CaO caused by CO2 adsorption–hydrogenation cycles and the carbon deposition side reactions caused by Fe. DFMs with a Mo/Fe mass ratio of 1:9 exhibited a CO2 capture capacity of 14.8 mmol/g DFM, a CO yield of 11.4 mmol/g DFM, and good cyclic properties at 650 °C, making it a promising DFM for ICCC–RWGS. In conclusion, the utilization of superstructures with superior redox reactivity and structural stability, such as perovskite and spinel, offers valuable insights into the design of DFMs for ICCC.

The application of ZIF nanomaterials as controlled release agents for pesticides holds significant promise in enhancing pesticide utilization efficiency, prolonging their effectiveness, and minimizing pesticide residues. However, the loading efficiency of single ZIF is limited and susceptible to external stimuli. Therefore, in order to improve the loading rate of the material and enhance the bioavailability of the pesticide, a novel porous nanocarrier (MPN (Fe) @ZIF-8) was prepared for loading the neonicotinoid pesticide thiacloprid (THIA) by combining the biocompatible material metal polyphenol network (MPN) with ZIF-8 using the co-precipitation method and layer-by-layer self-assembly strategy. Through the selection of carrier materials and optimization of loading conditions, MPN (Fe) @ZIF-8 with irregular coral-like structure was obtained, which had high specific surface area (82.15 m 2 /g) and excellent load ratio (18.93 %). In addition, with the aim of preventing pesticide leakage, polyethyleneimine (PEI) was added to the nanocarrier system as a sealing agent, and porous ZIF nanopesticides with pH-responsive properties (MPN (Fe) @ZIF-8@THIA@PEI) were prepared. In vitro release experiments showed that MPN (Fe) @ZIF-8@THIA@PEI favoured the release of THIA (72.33 % cumulative release) under alkaline conditions (pH = 8.6), whereas it was delayed (42.24 % cumulative release) under acidic conditions (pH = 3.6). It was noteworthy that MPN (Fe) @ZIF-8@THIA@PEI has a higher lethality rate (89.04 %) against B. tabaci than commercial THIA reagents (66.67 %). Furthermore, after 8 h of UV irradiation, the residual pesticide in the commercial THIA reagent was only 11.27 %, while that in MPN (Fe) @ZIF-8@THIA@PEI remained at 73.98 %. Hence, this work provides new ideas for the development of green and environmentally friendly stimuli-responsive porous controlled release agents.
