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.

Solid polymer electrolytes (SPEs) have been considered the most promising separators for all-solid-state lithium metal batteries (ASSLMBs) due to their ease of processing and low cost. However, the practical applications of SPEs in ASSLMBs are limited by their low ionic conductivities and mechanical strength. Herein, we developed a three-dimensional (3D) interconnected MXene (Ti 3 C 2 T x ) network and Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) particles synergistically reinforced polyethylene oxide (PEO)-based SPE, where the association of Li + with ether-oxygen in PEO could be significantly weakened through the Lewis acid-base interactions between the electron-absorbing group (Ti–F, −O–) of Ti 3 C 2 T x and Li + . Besides, the TFSI − in lithium salts could be immobilized by hydrogen bonds from the Ti–OH of Ti 3 C 2 T x . The 3D interconnected Ti 3 C 2 T x network not only alleviated the agglomeration of inorganic fillers (LLZTO), but also improved the mechanical strength of composite solid electrolyte (CSE). Consequently, the assembled Li||CSE||Li symmetric battery showed excellent cycling stability at 35 ℃ (stable cycling over 3000 h at 0.1 mA cm −2 , 0.1 mAh cm −2 ) and −2 ℃ (stable cycling over 2500 h at 0.05 mA cm −2 , 0.05 mAh cm −2 ). Impressively, the LiFePO 4 ||CSE||Li battery showed a high discharge capacity of 145.3 mAh/g at 0.3 C after 300 cycles at 35 ℃. This rational structural design provided a new strategy for the preparation of high-performance solid-state electrolytes for lithium metal batteries.

Metal corrosion and mechanical wear result in a serious decrease in the service life of marine engineering equipment. Carbon-based quantum dots (CDs) are often used as corrosion inhibitors or lubricants due to their ease of functionalization and quantum size effect. However, the protection efficiency of CDs is limited by weak adsorption capacity, and additional doping of heteroatoms such as N and S is usually needed to enhance the adsorption. Here, Ti 3 C 2 T x quantum dots (MQDs) were synthesized by using two-dimensional Ti 3 C 2 T x sheets containing abundant functional groups on the surface as precursors. The corrosion inhibition efficiency of MQDs with a concentration of 400 mg L −1 reached 94.2 %, and the coefficient of friction and wear rate were reduced by 67.6 % and 83.2 %, respectively, compared with the single NaCl solution. Surface analysis showed that MQDs blocked the penetration of corrosive species via forming a protective film on the steel surface through the formation of Ti–O–Fe coordination bonds. Notably, the thickness of protective film was affected by the pH of solution, reaching a maximum thickness of 215 nm at the NaCl solution with a pH of 7. Finally, density functional theory and molecular dynamics simulations were utilized to deeply reveal the adsorption mechanism of MQDs. This study provides new insights into the role of MQDs as dual-functional additives, which is of great significance in promoting the development of multifunctional marine engineering protective materials.

Given their high theoretical capacity, alloy-based anodes are promising candidates for lithium-ion batteries (LIBs) to meet the stringent demand of today's portable electronic devices and electric vehicles. However, the intrinsic limitations of volume expansion and irreversible pulverization lead to the sharp capacity decay and short cyclic life of the LIBs. Liquid metal (LM), possessing an inborn large capacity and inheriting deformability as liquids, can fundamentally avoid a large volume change during the electrochemical reactions. Herein, we report a facile strategy to self-assemble 2D Ti3C2Tx MXene into a 3D architecture, and simultaneously in situ encapsulate eutectic gallium indium (EGaIn) within the individual “MXene cell”. Inside the cell, the extraction of lithium ions from the ternary solid alloy brings LM back to the binary liquid state, enabling a self-healing process of the cracked or pulverized structure; outside the cell, the elastic network of the Ti3C2Tx skeleton buffers the volume expansion of the lithiated EGaIn. The as-prepared LM-Ti3C2Tx anode exhibited a superior rate capability (489 mA h g−1 at 5 A g−1) and excellent cycling stability (409.8 mA h g−1 after 4500 cycles at 5 A g−1, 90.8% capacity retention). Furthermore, we demonstrated that the reversible liquid–solid phase transformation and the formation of a distinct indium core/gallium shell structure is responsible for its self-healing properties. This work shows great potential for solving the inherent volume expansion problems of alloy-based anode materials.

The developments in hydrogen evolution reaction (HER) and supercapacitor technologies for electrochemical energy storage and conversion have received considerable attention. Although MoS 2 is electrochemically active for both HER and supercapacitors, limited active sites, slow ionic transport, and poor conductivity lead to its poor capacitance and electrocatalytic activity . Herein, hierarchical Ti 3 C 2 T x /MoS 2 /Ti 3 C 2 T x @CC (TMT@CC) composites were well-designed as electrodes for both HER and supercapacitors. Flexible TMT@CC electrodes with an area as large as ∼ 80 cm 2 and optimal mass-loading of 17.9 mg cm −2 were achieved. The inner layer Ti 3 C 2 T x in the composites provides ideal nucleation sites for the growth of MoS 2 arrays, and the outermost Ti 3 C 2 T x effectively anchors the vertically arrayed MoS 2 . The hierarchically vertical structure provides strong interfacial coupling and shortens ion diffusion paths, leading to high stability and fast ion/electron transport kinetics. Due to such a synergistic effect, the flexible binder-free TMT@CC electrodes exhibited high areal capacitance (5.06 F cm −2 at 5 mA cm −2 ) for supercapacitors and low overpotential (119 mV versus RHE at 10 mA cm −2 ) for HER catalyst. Furthermore, a high energy density of 0.125 mWh cm −2 at a power density of 1.5 mW cm −2 has been achieved from the TMT@CC-based symmetric supercapacitor . Our strategy can be expanded to other vertically arrayed hierarchical structures as electrode materials of efficient HER and supercapacitors.

A flexible sensor can be applied to monitor human motion, which can further be engineered with soft robotics to monitor their motion in the real time. However, to realize deformation detection with high-sensitivity in soft robots while simultaneously maintaining a high linearity and cyclic stability of the sensor yet remains as an unmet challenge. Herein, we fabricated strain sensors exhibiting a buckle and a sandwich like structure by spraying MXene (Ti 3 C 2 T x )/carbon nanotubes (CNTs)/fluoro-rubber composite materials onto a 200 % pre-stretched flexible rubber substrate. The resulting strain sensors displayed a wide range of detection (e.g., 1–150 %), high sensitivity (gauge factor (GF) for up to 461), good linearity, fast response time (21.2 ms), large stretching (150 %) as well as, excellent repeatability and stability. This sensor can further monitor the human physiology and the motion of the body. We also developed a soft robot with integrated sensors that enabled it to crawl like a caterpillar while leveraging its sensing function to detect its status in the real time. Conclusively, these hybrid strain sensors may have broad implications for robotics as well as wearable sensors for health monitoring and physiological recordings.

We report the fabrication of a lithiophilic Ti 3 C 2 T x MXene-modified carbon foam (Ti 3 C 2 T x -MX@CF) for the production of highly-stable LMBs that regulates Li nucleation behavior and reduces the volume change of a lithium metal anode (LMA). The 3D CF skeleton with a high specific surface area not only reduces the local current density to avoiding concentrated polarization, but also provides enough space to absorb the volume expansion during cycling. The excellent lithiophilicity of Ti 3 C 2 T x -MX produced by its abundant functional groups reduces the Li nucleation overpotential, guides uniform Li deposition without the formation of Li dendrites, and maintains a stable SEI on the anode surface. Consequently, a Li infiltrated Ti 3 C 2 T x -MX@CF symmetrical cell has an excellent cycling stability for more than 2 400 h with a low overpotential of 9 mV at a current density of 4 mA cm -2 and has a capacity of 1 mA h cm -2 . Furthermore, a Li- Ti 3 C 2 T x -MX@C||NCM111 full cell has a capacity of 129.6 mA h g -1 even after 330 cycles at 1 C, demonstrating the advantage of this method in constructing stable LMAs.

For wearable thermal management, phase change materials (PCMs) with solar-thermal conversion capacity are highly desired. However, traditional solid–liquid PCMs suffer challenges such as inherent solid stiffness, liquid leakage, and limited motion sensing capability. Herein, the flexible POE elastomer functions as a continuous supporting phase encasing n-octadecane in these innovative Ti3C2Tx MXene/polyolefin elastomer (POE)-based phase change foaming films (FPPMs), which have high flexibility and form stability, superior solar-thermal conversion efficiency, and sensitive motion detection. The supercritical carbon dioxide (scCO2) foaming technique was employed to enhance the flexibility and thermal insulation performance of the synthesized flexible phase change films. The FPPMs demonstrated a relatively high energy storage density (147.6 J/g), excellent form stability, superior thermal management performance, and remarkable flexibility (tensile stress up to 1000 kPa). Additionally, the incorporation of single-layer Ti3C2Tx MXenes significantly enhanced the solar-thermal conversion efficiency (up to 86.94%) and improved the motion detection sensitivity of the PCM films. The FPPMs can be employed as a strain sensor to detect various human motions, including facial expression, wrist bend, elbow bend, and finger bend.

A gold nanoparticle (AuNP)-Ti 3 C 2 T x -MXene-poly(diallyldimethylammonium chloride) (PDDA)-reduced graphene oxide (rGO) composite was prepared for electrochemical detection of hexavalent chromium (Cr (VI)). Firstly, Ti 3 C 2 T x -MXene was prepared by HF etching of aluminum titanium-carbide (Ti 3 AlC 2 ), and AuNP-MXene composite was prepared by self-reduction method. Then, the PDDA functionalized rGO (PDDA-rGO) was prepared by hydrothermal reduction method. Finally, the AuNP-Ti 3 C 2 T x was assembled on PDDA-rGO by the electrostatic interaction, and an AuNP-Ti 3 C 2 T x -PDDA-rGO composite was obtained. The composition and morphology were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and Raman spectroscopy. The electrochemical behavior of Cr (VI) on the composite modified electrode was studied carefully. The results showed that PDDA-rGO can be used as a good carrier to firmly load AuNP-Ti 3 C 2 T x by electrostatic interaction. The simultaneous introduction of AuNP and Ti 3 C 2 T x enhanced the electrochemical activity of the composite. Under the synergistic action of various components, the composite showed strong catalytic activity for the electrochemical reduction of Cr(VI). The linear range of amperometric detection of Cr(VI) was 2.0 × 10 −8 –1.1 × 10 −5 mol/L and 1.1 × 10 −5 –3.9 × 10 −4 mol/L. respectively. The detection limit is 1.0 × 10 −8 mol/L (S/N = 3). The composite electrode had the characteristics of low detection limit, high sensitivity and wide linear range, and can be used for quantitative determination of Cr (VI) in water samples.

MXenes show potential applications in sustainable energy due to their distinct layered structure, large surface area, adjustable surface chemistry and good conductivity, but the big challenge still remains in achieving both high specific capacitance and excellent stability. Herein, ternary strategy of 0D/1D/2D composite was proposed to realize high-performance supercapacitors (SCs) by synergy effect of silver nanoparticles and silver nanowires with Ti 3 C 2 T x . The enhancement in interlayer spacing, specific surface area and electrochemical conductivity resulted in abundant electrochemical active sites and improved ionic accessibility. Therefore, the ternary electrode exhibited excellent specific capacitance and superior cyclic stability, and it showed a specific capacitance of 796.6F g −1 at 2 mV s −1 , more than twice of 387.7F g −1 for Ti 3 C 2 T x . Moreover, the capacitance retention for ternary electrode was 98.2% after 10,000 CV cycles at 50 mV s −1 , comparable to 99.2% for Ti 3 C 2 T x . Furthermore, the symmetric SC with ternary electrode demonstrated specific capacitance of 109F g −1 at 2 mV s −1 with capacitance retention of 96.1% after 10,000 cycles, highlighting great potential for sustainable energy.

Hydrogen plays a vital role in zero-carbon energy systems and lithium-ion battery health monitoring, while its safe utilization faces a critical challenge in achieving high-accuracy room-temperature detection with fast response speed. Herein, Ti 3 C 2 T x ternary composites decorated with Pd and SnO 2 nanoparticles (MPS) are successfully synthesized via a facile approach at 80 ˚C with a high hydrogen sensitivity based on a synergetic effect. Within the MPS composites, the dissociation energy barrier for hydrogen molecules can be drastically reduced with the existence of Pd nanoparticles, boosting the ionization of active hydrogen atoms at the heterointerface between SnO 2 and MXene via the hydrogen spillover effect. The isomorphous substitution of Ti 3+ by Sn 4+ generates abundant holes at the heterointerface, and the built-in electric field formed at the heterointerface subsequently promotes the recombination of these holes with the electrons generated during hydrogen ionization. Benefitting from the series of reaction, the optimal response of 73.5% is obtained with fast response/recovery time of 47 s/36 s upon exposure to 200 ppm H 2 at room-temperature. In addition, an outstanding linearity (R 2 =0.9908) is achieved within a range between 5 and 200 ppm, resulting in a superior LOD of 1.96 ppm. The MPS composite gas sensor simultaneously exhibits exceptional selectivity and cycling stability, shedding light on the new perspective of high-performance room-temperature gas sensing.

In this study, an innovative dual-functional zero-dimensional/two-dimensional carbon dots/monolayer Ti 3 C 2 T X (CDs/mon.Ti 3 C 2 T X ) heterojunction material was developed for sensitive fluorescence detection of histamine (HA) and visual monitoring of food freshness. Through electrostatic adsorption and hydrogen bonding, CDs were uniformly anchored onto the surface of mon.Ti 3 C 2 T X , forming a stable 0D/2D heterojunction structure. This architecture not only facilitated efficient charge separation but also promoted the interaction with and enrichment of HA, thereby enhancing the fluorescence response. In the fluorescence detection mode, the CDs/mon.Ti 3 C 2 T X heterojunction exhibited an excellent linear response to HA in the concentration range of 0.01–5 mg/mL ( R 2 = 0.9925), with a detection limit of 0.0065 mg/mL, demonstrating acceptable sensitivity and good stability. Moreover, the heterojunction enabled visual monitoring of food freshness through distinct color changes under natural light. By integrating fluorescence-based HA detection with visual freshness monitoring, this work provides an efficient, and practical strategy for biogenic amine detection in food and freshness evaluation of perishable seafood, highlighting its promising potential for food quality and safety assessments.
