The corrosion of ancient bronze relics and protection measures after excavation are of great importance to the study of historical and cultural heritage. At present, the bionic superhydrophobic surface anticorrosive coating is one of the main anticorrosive measures of bronze cultural relics. It aims to construct a barrier to prevent the contact between corrosive media and bronze to reduce the invasion of corrosive media. However, due to structural defects such as micropores in a single organic coating, corrosive media (O2, Cl–, and H2O) can penetrate the coating to the metal matrix. Nanomaterials such as MXenes and metal–organic frameworks (MOFs) can fill structural defects such as microholes and microcracks of the coating, thereby improving the density of the coating. Therefore, to improve the performance of organic waterborne polyurethane (WPU) coatings with good chemical protection, nanomaterial ZIF-8/Ti3C2Tx was introduced based on the organic–inorganic hybrid theory. Finally, the coating was modified by 1H,1H,2H,2H-perfluorodecyltriethoxysilane, and the organic–inorganic composite coating was prepared. Characterizations of the composite coating were performed via Fourier transform infrared spectroscopy, X-ray diffraction, Brunauer–Emmett–Teller method, field-emission scanning electron microscopy/energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. Colorimetric measurements and reversibility experiments of the coating were also evidenced. According to the electrochemical impedance spectroscopy assessments, the |Z|0.01 Hz value of the F-WPU@ZIF-8/Ti3C2Tx composite coating in a 3.5 wt % NaCl solution, which was higher compared to other composite coatings. Moreover, the icorr value of the F-WPU@ZIF-8/Ti3C2Tx (3.344 × 10–6 A cm–2) composite coating is reduced by 2 orders of magnitude compared with F-WPU@ZIF-8 and F-WPU@Ti3C2Tx coatings. As a result, this organic–inorganic F-WPU@ZIF-8/Ti3C2Tx composite coating has good anticorrosion properties to bronze without causing an obvious color difference change and has potential application prospects in various metal material fields.

The proliferation of micro/nanoplastics (MNPs) has emerged as a pivotal environmental issue, largely due to their potential for human exposure. Consequently, the development of sensitive and efficient detection methodologies is paramount for elucidating their environmental footprint. Here, we report a novel three-dimensional (3D) surface-enhanced Raman scattering (SERS) sensor, which integrate Ti 3 C 2 T x /TiO 2 /W 18 O 49 semiconductor heterostructure, for the rapid and sensitive detection of MNPs in environmental matrices. The sensor's unique layered architecture and efficient charge transfer mechanism endow it with high sensitivity. It has demonstrated remarkable detection capabilities, achieving a sensitivity of 10 −8 M for Rhodamine 6G (R6G), equating to an enhancement factor (EF) of 2.33 × 10 6 . This level of sensitivity allows for the detection of polystyrene (PS) microplastics at concentration as low as 25 μg/mL, with a relative standard deviation (RSD) of 12.58 %, signifying superior reproducibility. Moreover, the sensor's fingerprinting capabilities enable the identification of a variety of MNPs, including polyethylene (PE) and polyethylene terephthalate (PET), thus facilitating the analysis of complex MNPs mixtures. The sensor's applicability to real-world samples was confirmed through the quantitative detection of PS microplastics in rainwater, soil, and industrial wastewater, with a detection limit of 25 μg/mL and exhibiting good linearity. It is concluded that the 3D SERS sensor is a promising tool for the rapid and precise detection of MNPs across diverse environmental matrices. The advent of this technology marks a significant leap forward in environmental analysis, providing a robust method for the monitoring of MNPs pollution.

Friction damage is always a major threat to the wide application of smart anticorrosion coatings. Here, the tribological properties of a smart Ti 3 C 2 T x -based epoxy coating (MLT@EP) is adjusted by the reasonable collocation of mesoporous silica nanocapsules loading onto Ti 3 C 2 T x -based plane (MLT). MLT@EP not only maintains good smart anticorrosion, but also has remarkable anti-friction and anti-wear properties. Its friction coefficient exhibits a low and steady trend, and the wear rate arrived at 1.14 × 10 −5 mm 3 /N·m, which is decreased by 58.3 ∼ 93.3 % compared to control groups. The excellent tribological properties are mainly attributed to the synergistic effect of MXene-based lubrication film, high resistance to plastic deformation, and strong internal interaction.

Considering the vital physiological functions of dopamine (DA) and uric acid (UA) and their coexistence in the biological matrix, the development of biosensing techniques for their simultaneous and sensitive detection is highly desirable for diagnostic and analytical applications. Therefore, Ti3C2Tx/rGO heterostructure with a double-deck layer was fabricated through electrochemical reduction. The rGO was modified on a porous Ti3C2Txelectrode as the biosensor for the detection of DA and UA simultaneously. Debye length was regulated by the alteration of rGO mass on the surface of the Ti3C2Txelectrode. Debye length decreased with respect to the rGO electrode modified with further rGO mass, indicating that fewer DA molecules were capable of surpassing the equilibrium double layer and reaching the surface of rGO to achieve the voltammetric response of DA. Thus, the proposed Ti3C2Tx/rGO sensor presented an excellent performance in detecting DA and UA with a wide linear range of 0.1–100 μM and 1–1000 μM and a low detection limit of 9.5 nM and 0.3 μM, respectively. Additionally, the proposed Ti3C2Tx/rGO electrode displayed good repeatability, selectivity, and proved to be available for real sample analysis.

Nano-enzymes are increasingly used in forensic identification, biochemical testing, food regulation, environmental pollution monitoring and other fields. However, the construction of enzyme cascade catalytic systems based on nano-enzymes with multiple enzyme activities presents both opportunities and challenges. Ti3AlC2 is a common MXene with a graphene-like structure, which has the features of a large specific surface area, good electrical conductivity, excellent catalytic properties, and easy functionalization. Moreover, after being functionalized, Ti3AlC2 can exhibit excellent peroxidase-like activity. Therefore, in this work, a bimetallic Fe–Ni@Ti3C2Tx nano-enzyme with both peroxidase-like and oxidase-like activities was synthesized, and three synergistic catalytic mechanisms of Fe–Ni@Ti3C2Tx were verified. A colorimetric sensor was constructed based on Fe–Ni@Ti3C2Tx for the detection of H2O2 to test its feasibility for practical applications. The prepared colorimetric sensor had a wide linear range (50–6000 µM) and a low detection limit (14.606 µM). In addition, the selectivity, stability and reproducibility of the prepared colorimetric sensor were acceptable. This study laid a foundation for the simple preparation and practical application of a bimetallic nano-enzyme with various enzyme activities.

Piezoelectric nanogenerator (PENG) for practical application is constrained by low output and difficult polarization. In this work, a kind of flexible PENG with high output and self-polarization is fabricated by constructing CsPbBr 3 –Ti 3 C 2 T x heterojunctions in PVDF fiber. The polarized charges rapidly migrate to the electrodes from the Ti 3 C 2 T x nanosheets by forming heterojunctions, achieving the maximum utilization of polarized charges and leading to enhanced piezoelectric output macroscopically. Optimally, PVDF/4wt%CsPbBr 3 /0.6wt%Ti 3 C 2 T x -PENG exhibits an excellent voltage output of 160 V under self-polarization conditions, which is higher than other self-polarized PENG previously. Further, the working principle and self-polarization mechanism are uncovered by calculating the interfacial charge and electric field using first-principles calculation. In addition, PVDF/4wt%CsPbBr 3 /0.6wt%Ti 3 C 2 T x -PENG exhibits better water and thermal stability attributed to the protection of PVDF. It is also evaluated in practice by harvesting the energy from human palm taps and successfully lighting up 150 LEDs and an electronic watch. This work presents a new idea of design for high-performance self-polarization PENG.

The rapid development of modern wireless communication technology makes electromagnetic wave pollution increasingly serious, necessitating the development of high-performance electromagnetic wave-absorbing materials. This study introduces a Ti 3 C 2 T x MXene hybrid carbon foam (HCF) that exhibits a tunable and efficient electromagnetic wave absorption performance. The HCF features a porous, multilayered structure, which enhances its multi-reflection properties, and a heterogeneous interface between the carbon foam and MXene boosting its dielectric loss. By regulating the content of MXene, the ratio of polarization loss to conduction loss can be regulated to achieve better impedance matching. As a result, the HCF demonstrated superb electromagnetic wave absorption performance with RL min = −72.25 dB and EAB max = 6.55 GHz. Furthermore, the minimum absorption frequency domain could be tuned within 8–14 GHz by varying the MXene content. The performance in radar wave absorption and electromagnetic-thermal conversion (ramp rate 85.81 °C/s from RT to 200 °C) proves that HCF is an efficient and reliable electromagnetic wave absorber, suitable for radar technology, microwave heating, and communication systems applications.

MXenes have shown great potential for supercapacitor electrodes due to their unique characteristics, but simultaneously achieving high capacitance, rate capability, and cyclic stability along with good mechanical flexibility is exceptionally challenging. Here, highly enhanced capacitance, rate capability, and cyclic stability, as well as good mechanical flexibility for T3C2Tx MXene-based supercapacitor electrodes are simultaneously obtained by engineering the electrode structure, modifying the surface chemistry, and optimizing the fabrication process via an optimized integration approach. This approach combines and more importantly optimizes three methods that all require a calcination process: carbonizing in situ grown polymer (“Cpolymer”) on the MXene, alkali treatment (“A”), and template sacrificing (“P”); and the optimized processes lead to more abundant active sites, faster ion accessibility, better chemical stability, and good mechanical flexibility. The obtained P-MXene/Cpolymer-A electrodes are binder-free and self-supporting and not only have good mechanical flexibility but also demonstrate much larger capacitances and better rate performance than the pristine MXene electrode. Specifically, the P-MXene/CPAQ-A electrode (PAQ: quinone-amine polymer) achieves a high capacitance of 532.9 F g–1 at 5 mV s–1, together with superior rate performance and improved cyclic stability (97.1% capacitance retention after 40 000 cycles at 20 A g–1) compared with the pristine MXene (79.6% retention) and P-MXene-A (77.3% retention) electrodes. In addition, it is discovered that carbonizing in situ grown polymers can variously remove the −F group and the removal effect can be accumulated with that by the alkali treatment.

Succinonitrile has shown significant promise for application in polymer electrolytes for solid-state lithium metal batteries due to its high ionic conductivity at low-temperature. However, the use of Succinonitrile is limited due to its corrosion of Li metal. Herein, we report a solid polymer electrolyte with high ionic conductivity (2.17 × 10 −3 S cm −1 , 35 °C) enhanced by Ti 3 C 2 T x . Corrosion of the Li anode is prevented due to the Succinonitrile molecules being efficiently anchored by Ti 3 C 2 T x . Meanwhile, the coordination environment of Li + is weakened due to the introduction of competitive coordination induction effects into the polymer electrolyte, resulting in efficient Li + conduction. Furthermore, the mechanical properties of the electrolyte are enhanced by modulating the ratio of Ti 3 C 2 T x to suppress the growth of Li dendrites. Therefore, Li||Li symmetric batteries deliver stable cycling up to 8000 h at 28 °C. LiFePO 4 ||Li full batteries exhibit excellent cycling stability of 151.7 mAh g −1 with a capacity retention of 99.3% after 300 cycles. This work not only presents a new idea to suppress the corrosion of the Li anode by Succinonitrile but also provides a simple, feasible, and scalable strategy for high-performance Li metal batteries.

The microwave-assisted hydrothermal method has facilitated the straightforward and efficient production of nanoscale Ce x Zr 1−x O 2 /Ti 3 C 2 T x composites. This technique has greatly shortened the synthesis time several hours required by conventional hydrothermal method to merely 10 min. Due to the unique mechanism of microwave-hydrothermal synthesis, composites with excellent crystallinity, uniform particle size, and superior degradation capabilities can be obtained without calcination. Our investigation systematically explores the influence of various factors including mineralizer concentration, dispersant types, synthesis duration, cerium-to-zirconium ratio, as well as MXene content on the material properties. Optimal degradation of 2-chloroethyl ethyl sulfide (2-CEES), sulfur mustard simulants, is achieved using PEG1000 as the dispersant, a cerium-to-zirconium ratio of 1:2, along with 15 mL of MXene, resulting in a remarkably short half-life of only 6.5 min. Furthermore, it is confirmed that the incorporation of cerium atoms into ZrO 2 lattice, forming a solid solution that is deposited onto the interlayer and surface of Ti 3 C 2 T x nanosheets, with the composite particles measuring approximately 5.01 nm. The reduced size and increased specific surface area, coupled with the synergistic effects of oxygen vacancies and acid-base sites, ultimately contribute to the hydrolysis and elimination reactions occurring on 2-CEES. This research offers fresh perspectives on the development of novel materials for the degradation of chemical warfare agents.

Transplant-associated bacterial infections, especially the formation of bacterial biofilms, frequently lead to persistent infections and even transplant failure. Herein, a near-infrared laser-triggered nanosystem with antibacterial and anti-biofilm activities is constructed by loading S-nitrosothiols (RSNO) onto Ti 3 C 2 T x nanosheets, which are then mixed with poly-L-lactic acid (PLLA) powders to prepare porous PLLA/Ti 3 C 2 T x -SNO scaffolds. Especially, the excellent photothermal property of the scaffold is expected not only to eliminate bacterial biofilms but also to trigger RSNO molecules to in situ release nitric oxide (NO) gas under near-infrared laser irradiation. Moreover, the removal of the biofilms facilitates more NO to enter and kill the deep bacteria through nitridation damage, thus realizing the synergistic antibacterial capabilities of photothermal and NO gas therapies. The experimental results showed that the photothermal conversion efficiency of the scaffold reached 39 %. Combining with the in situ NO release, the scaffold presented excellent anti-biofilm and antibacterial activities, with antibacterial rates of 93.6 % and 94.9 % against E. coli and S. aureus , respectively. This work is expected to solve the dilemma of treating bacterial infections in deep tissues, providing reference for the clinical treatment of transplant-associated bacterial infections and even extending to the treatment of other deep refractory infections.

Molybdenum disulfide (MoS2) has great potential as an anode material for lithium-ion batteries due to its graphite-like layered structure and high specific capacity (669.0 mA h g−1). However, challenges such as volume expansion during lithium storage have impeded its utilization. The combined alteration of MoS2 and MXenes has demonstrated its efficacy as a modification technique. In this study, a green and facile phase engineering strategy has been implemented for the synthesis of MoS2/Ti3C2Tx nanocomposites. Ti3C2Tx was rapidly prepared by the fluorine-free molten salt etching method, and then the MoS2/Ti3C2Tx composite was synthesized by the one-pot method. Fluffy and open petal-like interconnect structures were constructed by combining few-layer MoS2 nanosheets with Ti3C2Tx substrate. The introduction of the substrate material (Ti3C2Tx) provides a uniform growth platform for MoS2 nanosheets, and Ti3C2Tx, acting as the supporting material, imparts enhanced structural stability to the composite. Theoretical calculations indicate that this configuration may result in a reduction of the diffusion energy barrier of Li+ from 0.78 eV to 0.19 eV, as well as an enhanced electron transfer. This composite material exhibits enhanced capacity performance, achieving 460.6 mA h g−1 at 0.1 A g−1 after 100 cycles. This approach offers valuable insights into the synthesis of additional high-performance composite materials.
