Piezocatalytic hydrogen peroxide (H 2 O 2 ) production holds promise as a sustainable technology, but its practicability is hindered by inadequate polarization fields, sluggish charge transport, and rapid bulk carrier recombination. Herein, we propose a catalyst-design strategy integrating bulk iodine doping with surface MXene cocatalyst coupling in a typical piezoelectric bismuth titanate (Bi 4 Ti 3 O 12 , BTO). This design generates intensified bulk polarization fields that markedly suppress electron-hole recombination, while MXene functions as an efficient interfacial electron sink, significantly reducing surface kinetic barriers by facilitating electron transfer for the oxygen reduction reaction (ORR). The optimized iodine-doped MXene-coupled BTO (MBTO-I) catalyst demonstrates a piezocatalytic H₂O₂ production rate of 5890 µmol g⁻¹ h⁻¹ under ambient conditions without any sacrificial agents. Theoretical calculations and advanced characterization techniques reveal that iodine doping effectively lowers energy barriers for *OH intermediate formation and stabilizes O–H bonds, while MXene coupling significantly improves interfacial charge transfer and accelerates the ORR kinetics. Furthermore, the produced H 2 O 2 was successfully employed for bacterial sterilization and rapid degradation of pollutants. Subsequent chemical analyses and biological assessments confirm a substantial reduction in the toxicity of sulfamethoxazole (SMX) degradation products, highlighting the catalyst’s considerable potential for environmental remediation applications.

Aerogel materials are becoming increasingly popular. However, their multi-field applications in complex environments still face challenges. Here, a multifunctional MXene/BC/KH560 composite aerogel (MBKA) with excellent comprehensive properties was prepared using chemical cross-linking and directional freeze-drying technologies. This aerogel is characterized by its lightweight nature, favorable mechanical properties, and controllable surface wettability. Outstanding electromagnetic interference (EMI) shielding performance and photothermal capabilities are endowed by the incorporation of MXene. MBKA achieves an EMI shielding effectiveness of 23.47 dB in the X-band (8.2–12.4 GHz). Additionally, it can heat up to 105.1 °C within 180 s under solar radiation. After hydrophobic modification, a high water contact angle (WCA > 150°) is exhibited by MBKA. Furthermore, its modified and optimized version is suitable for oil/water separation, with an oil absorption capacity ranging from 30.4 to 94.7 g g −1 . Owing to its remarkable photothermal conversion capability, ice formation is effectively prevented or removed by MBKA at −15 °C, with an extended ice delay time (64 min) and rapid photothermal de-icing (55 s) being demonstrated. Therefore, this work provides a valuable strategy for designing multifunctional composite aerogels, demonstrating broad prospects for multi-scenario applications in complex environments.

Psoriasis, a globally prevalent immune-mediated dermatosis, requires novel therapeutic strategies that address its multifactorial pathogenesis, involving oxidative stress, cell-free DNA (cfDNA)-driven inflammation, and keratinocyte hyperproliferation. Here, we presented a pH-responsive two-dimensional (2D) MXene nano-scavenger integrating Ti 3 C 2 T x -mediated antioxidant activity, polyethylenimine (PEI)- facilitated cfDNA scavenging, and 2,3-dimethylmaleic anhydride (DMMA)-induced charge reversal for targeted ATIC inhibitor delivery. Comprehensive material characterization confirmed pH-dependent charge reversal and sustained drug release. In vitro, the MXene-based platform (MPDA) exhibited superior reactive oxygen species (ROS) scavenging (superior to Trolox at the same concentration) and cfDNA adsorption (3-fold higher than pure MXene), while in vivo administration in imiquimod-induced psoriatic mice markedly alleviated disease severity (PASI score reduction of approximately 50%), reduced epidermal thickness (37% decrease compared to the IMQ group), and suppressed inflammatory cytokines—significantly outperforming monotherapies. Transcriptomic analysis further revealed that MPDA cooperatively inhibited multiple inflammatory pathways, including the TNF and IL-17 signaling, thereby effectively disrupting the self-perpetuating inflammatory cycle of psoriasis. This work establishes a promising paradigm for combinatorial nanotherapy in psoriasis treatment.

The rapid development of the nuclear industry has made the efficient treatment of uranium-containing wastewater a significant challenge in environmental radiochemistry. This study aimed to develop a high-performance adsorbent for the removal of UO 2 2+ from water. A series of MIL-125/Ti 3 C 2 nanocomposites were successfully constructed via an in-situ solvothermal method, by integrating two-dimensional Ti 3 C 2 MXene with rich surface functional groups and porous MIL-125(Ti) MOF. The composite material not only retained the regular pore structure of MIL-125 but also exposed a greater number of active sites, exhibiting optimal adsorption performance. Under neutral conditions (pH = 7), the adsorption of U(VI) onto MIL-125/Ti 3 C 2 –2 followed the pseudo-second-order kinetic model and reached equilibrium within 50 min, with a remarkable maximum adsorption capacity of 661.07 mg/g, clear superior to most reported adsorbents. The adsorption isotherm fitted the Langmuir model, indicating monolayer chemisorption. Furthermore, the material demonstrated excellent anti-interference ability and selectivity in the presence of various coexisting ions (except for Cu 2+ and Ca 2+ ) and humic acid, along with satisfactory regeneration performance (85.6% retention after 5 cycles). The adsorption mechanism involves strong coordination interactions between surface functional groups (-NH 2 , -OH) and UO 2 2+ , while the potential reducing ability of MXene also facilitates the partial reduction of U(VI) to the more stable U(IV), forming a dual fixation mechanism of ‘synergistic adsorption-reduction’. This work provides new insights and experimental evidence for designing efficient and stable MOF/MXene adsorbents for treating actual uranium-containing wastewater.

The development of iron-based heterogeneous Fenton catalysts is often hindered by challenges including slow Fe 3+ /Fe 2+ cycling, limited interfacial electron transfer kinetics, and inefficient mass transport, leading to suboptimal catalytic efficiency. In this work, three distinct assembly strategies—hydrogen bonding, electrostatic self-assembly, and solvothermal methods—were utilized to fabricate MCuFe-MOF/PMMA@MXene (denoted as MPM) microspheres for the photo-Fenton degradation of methylene blue (MB). Notably, the microspheres fabricated via electrostatic self-assembly (designated E -MPM) exhibited a unique three-dimensional (3D) microsphere architecture. This structure significantly enhanced the adsorption capacity for pollutants and improved mass transfer, concurrently broadening the visible-light absorption range. The well-defined interfaces within the E -MPM microspheres facilitate the formation of multiple heterojunctions with favorable band alignment, which effectively promotes the generation and separation of photogenerated electron-hole pairs. Consequently, highly reactive free radicals are efficiently generated through the photo-Fenton process, the E -MPM microspheres demonstrated high catalytic activity, achieving a remarkable MB degradation efficiency of approximately 91.9% within 60 min at 4 g/L MB under visible-light irradiation. This study not only provides a fundamental insight into the design of bimetallic MOF/MXene-derived heterogeneous photocatalysts, but also broadens the application scope of MXene-based materials in advanced water treatment technologies.

3-dimensional (3D) Fe−Co−LDH/MXene composite was synthesized by in-situ synthesis and assembly of Fe−Co−LDH rod around MXene under hydrothermal condition. Due to the unique 3D configuration and good conductivity, the obtained Fe−Co−LDH/MXene modified glassy carbon electrode (Fe−Co−LDH/MXene/GCE) showed excellent electrochemical activity for As(III) detection. Via square-wave anodic stripping voltammetry, the response current on Fe−Co−LDH/MXene/GCE had good linear relationship with As(III) concentrations (1∼1000 ppt) with superior sensitivity (0.22 μA ppt −1 cm −2 ) and low detection limit (0.9 ppt). The mechanism of As(III) adsorption was demonstrated. The electrode showed excellent anti-interference ability. Real water sample analysis demonstrated the Fe−Co−LDH/MXene/GCE was deployable in aqua-system.

In this study, the RGO/CNTs/MXene aerogel-epoxy composites (RCM-EP) were fabricated via freeze drying following by resin perfusion process. RCM aerogel with different pore sizes and morphologies were regulated by changing concentration of MXene . In addition, mechanical properties and thermal behaviors of EP composites with RCM and dispersed fillers were comparatively investigated. The results show that the RCM-EP have a better mechanical strength and thermal properties due to outstanding dispersion performance, interfacial bonding and spatial thermal conductivity network. Simultaneously, tribological test results revealed the wear rate and friction coefficient of EP were reduced by 83.5 % and 53.1 %, respectively, with the incorporation of RCM aerogel . The RCM aerogel inside the EP matrix could improve the bearing capacity of composites and inhibit the accumulation of friction heat via 3D inter-crosslinked network. Moreover, the RCM aerogel was slowly released and participated in friction transfer during sliding process, constructing high-quality transfer film, which endowed the RCM-EP with distinguished tribological performance .

In this work, a novel adsorbent for the removal of hexavalent chromium (Cr(VI)) in aqueous solution was successfully prepared by altering the 2D Ti 3 C 2 /chitosan composite with disodium ethylenediaminetetraacetate (EDTA·2Na) agent. The successful surface loading of chitosan on Ti 3 C 2 was demonstrated by various characterization methods, including scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR). The adsorption of Cr(VI) by Ti 3 C 2 -based composite under various circumstances was evaluated using batch adsorption experiments. The adsorption performance of the optimal sample for Cr(VI) was investigated in detail through different influencing factors, and the adsorption process was analyzed by adsorption kinetics and isotherm model. In addition, XPS analysis of adsorbents before and after adsorption showed that some Cr(VI) was reduced to Cr(III) during the whole process, which was conducive to reducing the biological toxicity of Cr(VI). The mechanism analysis showed that the adsorption was mainly electrostatic physical adsorption, supplemented by chemical reduction adsorption. Finally, through the regeneration cycle experiment, it was found that the adsorption rate of Cr(VI) remained above 80% after six repeated adsorptions, indicating that the composite material had good stability and might have certain practical application value in the treatment of Cr(VI)-containing wastewater.

Conductive ionic gels are considered as potential flexible sensing materials owing to their softness and biocompatibility. Nevertheless, pure ionic gels typically exhibit poor mechanical properties and low sensitivity. In this study, MXene and liquid metal (LM) are introduced for self-assembly to form a spring structure. The enhanced effect of the van der Waals force synergy between the two fillers increases the tensile resistance (925 %, 1091.5 kPa), compression resistance (75 %, 2534.3 kPa) and self-healing (∼90 % recovery) efficiency of the ionic gel. In addition, the conductive paths based on double fillers are greatly destroyed during the straining process, and show a very high gauge factor (15.47) because of their unique spring structure and weak viscous force between them. This study provides a new approach for the preparation of highly sensitive sensing materials for human body monitoring and applications in other domains.

MXene-based functional textiles have been widely studied and applied in many fields. However, the service stability of MXene combined with textile substrates in the environment is far from ideal, which makes its practical application a great challenge. Here we introduced gallic acid (GA), as natural reactive polyphenol compound to silk fibers through enzymatic polymerization, which significantly improved the durability of its conductivity. The small molecules of GA can covalently bind to the titanium atoms on the MXene nanosheets, and the tyrosine residues from silk fibroins can be enzymatically oxidized by horseradish peroxidase (HRP) and further coupled with GA simultaneously, thus forming a covalent cross-linked network on the fiber surfaces. Furthermore, the durable MXene-based textile was used to manufacture smart dual-driven thermal devices with temperature monitoring, which can judge the real-time temperature during heating by changes in its apparent color. More importantly, the textile with smart temperature visualization also offers good EMI shielding and superior UV resistance, while retaining its inherent moisture-wicking, breathable and softness. The present work provides a new insight for the preparation of MXene-based multifunctional textile, and the smart visualization of dual-driven heating shows promising applications in practical personal thermal management.

Efficient thermal management materials are important for the proper operation of integrated circuits. In this work, the high-yield preparation of hydroxylated boron nitride nanosheets (BNNSs) was achieved by high-temperature ablation followed by ultrasonic exfoliation without the use of highly toxic solvents. The small-sized BNNSs have similar phonon vibration properties as the large-sized MXene , and they self-assemble by electrostatic adsorption on PMMA particles to form hybrid spheres. The appearance of thermal percolation threshold indicates the successful construction of thermal conductivity pathway. The exclusion effect is more pronounced for PMMA microspheres with a larger radius, and the best thermal conductivity of 4.13 W/m·K was achieved for the composite with 20 wt% nanosheet filling. The composite exhibited good thermal performance both in the finite element model and when used as an LED heat sink. Furthermore, the incorporation of fillers can also effectively improve the thermal stability and mechanical properties of the composite. Our study provides a facile and environmental exfoliation approach of h-BN and a new strategy for the preparation of high thermal conductivity electronic packaging materials.

MXene film electrodes for supercapacitors, assembled with MXene nanosheets as structure units, inevitably suffer from self-restacking, which severely restrains ion transport kinetics and results in insufficient active site utilization and poor rate capability. Herein, an in situ foaming strategy employing the accumulated gas generated during the etching of sacrificial templates, combined with the confinement between the MXene film, has been proposed to fabricate pores between stacked MXene sheets and along the vertical direction of the film. The surface chemistry of the foamed film was further modified by alkali washing treatment to replace hydrophobic –F groups with hydrophilic –OH groups to improve electrolyte penetration and introduce more active sites. The resultant porous MXene film electrode exhibits a greatly improved specific capacitance (354.1 F g−1 at 5 mV s−1) and unparalleled rate capability (with a capacitance retention of 96.1% at 2000 mV s−1). This work demonstrates a facile but efficient method for the construction of porous MXene films, simultaneously providing insights into the promising applications of MXenes.
