Ternary copper-based Cu 3 SbSe 4 compound has emerged as a promising thermoelectric material. However, its practical application is limited by relatively low thermoelectric performance, primarily due to inferior electrical properties. In this work, the Cu 3 SbSe 4 -based composites with incorporated 2D MXenes ( i.e. , Ti 3 C 2 T x ) were synthesized by combining mechanical alloying with spark plasma sintering technique. The introduction of 2D Ti 3 C 2 T x nanosheets significantly enhanced the Seebeck coefficient, which is ascribed to the energy-dependent carrier scattering. Resultantly, an optimized PF ~ 1.1 mWm −1 K −2 can be realized in the bulk composite with x = 1.5. All composite samples exhibited low thermal conductivity in high temperature, attributed to enhanced interfacial phonon scattering. As a result, the best ZT value of 0.59 at 623 K is obtained for the bulk Cu 3 Sb 0.98 Sn 0.02 Se 4 /1.5 vol % Ti 3 C 2 T x composite, which increases by 31% compared with that of the matrix. This study demonstrates that incorporation of 2D MXenes into ternary copper-based compounds is an effective strategy to enhance their TE performance.

The Si-P nanohybrids, as an underlying candidate for the anode material of the next-generation lithium-ion batteries (LIBs), possess a high theoretical specific capacity of 2900 mAh g −1 but decays rapidly owing to the large volume change during lithiation/delithiation. Meanwhile, two-dimensional transition metal carbides (MXenes) with outstanding conductivity and specific crystal structure have been revealed with a relative low Li + diffusion barrier, which exhibits underlying application prospects in the area of energy storage and can be particularly utilized as the conductive matrix for realizing the outstanding performance of lithium storage. Herein, we employ an MXenes (Ti 3 C 2 T x )-buffer strategy to improve the electrochemical properties of the traditional Si-P anode by a relatively simple mechanical ball-milling method. Obvious chemical bonds between Si-P and Ti 3 C 2 T x have been confirmed for as-prepared Si-P/Ti 3 C 2 T x composites, where P nanolayer acts as an intermediate layer and guarantees the composite integrity and the tight contact between red phosphorus, Si, and Ti 3 C 2 T x matrix. Moreover, the Si-P/Ti 3 C 2 T x composite electrode, in comparison with Si-P composite and Si, exhibits an enhanced rate performance (632.4 mAh g −1 at 5A g −1 ) and a higher reversible capacity (980.8 mAh g −1 after 500 cycles at 500 mA g −1 ), indicating it’s a promising candidate for advanced LIBs anode. Graphical abstract The high-performance chemically bonded double-conductive protective layer lithium-ion battery anode was developed by mechanical ball-milling strategy.

Although ammonia gas sensor research has been developed for a long time, room temperature flexible ammonia gas sensors with high sensitivity and selectivity are still hot research topics. 2D transition metal carbides and nitrides (MXenes) have combined their versatile surface chemistry and high metal conductivity to show their enormous sensing potential. Herein, developing a room temperature nanocomposite based on 2D MXenes materials and cationic polyacrylamide (CPAM) with high gas response and flexibility targeting the construction of high-performance ammonia sensors is focused on. Thanks to the hydrogen bond composition, ohmic contact with the interdigitated electrodes, and excellent mechanical properties, the CPAM/Ti 3 C 2 T x -based ammonia sensors exhibit high ammonia selectivity, faster response–recovery rate (12.7/14.6 s), excellent flexibility, and long-term mechanical stability at room temperature. The synthesis of the CPAM/Ti 3 C 2 T x nanocomposites offers a lasting inspiration for developing high-performance flexible gas sensors.

Humidity-responsive actuators (HRA) have garnered significant interest across various domains. Since 2020, MXene have been extensively studied for their potential in HRA, demonstrating remarkable performance. Thus far, more than 70 MXene materials have been found. However, no systematic research regarding the distinctions in their applications in the field of HRA has been carried out, limiting the exploration of their broader potential. Herein, a systematic investigation of the HRA performance within the MXene (Nb 2 CT x , V 2 CT x , Ti 3 C 2 T x , and Nb 4 C 3 T x ) family has been conducted. The influences of atomic layer number, oxygen content, transition metal elements, film thickness, and moisture gradient on the actuation performance are thoroughly examined. It is demonstrated that the number of atomic layers plays an indispensably critical role in both the bending angle and the response/recovery time. Nb 2 CT x and V 2 CT x with fewer atomic layers show excellent performance. At 50% relative humidity, their maximum bending angles reach 210° and 202° respectively. The HRA are exemplified by the creation of a bionic butterfly and an intelligent switch, showcasing its broad application potential.

The conversion of CO2 into fuels and feedstock chemicals via photothermal catalysis holds promise for efficient solar energy utilization to tackle the global energy shortage and climate change. Despite recent advances, it is of emerging interest to explore promising materials with excellent photothermal properties to boost the performance of photothermal CO2 catalysis. Here, we report the discovery of MXene materials as superior photothermal supports for metal nanoparticles. As a proof-of-concept study, we demonstrate that Nb2C and Ti3C2, two typical MXene materials, can enhance the photothermal effect and thus boost the photothermal catalytic activity of Ni nanoparticles. A record CO2 conversion rate of 8.50 mol·gNi–1·h–1 is achieved for Nb2C-nanosheet-supported Ni nanoparticles under intense illumination. Our study bridges the gap between photothermal MXene materials and photothermal CO2 catalysis toward more efficient solar-to-chemical energy conversions and stimulates the interest in MXene-supported metal nanoparticles for other heterogeneous catalytic reactions, particularly driven by sunlight.

In this work, Ti 3 C 2 –Cl is introduced into poly(3,4-ethylenedioxythiophene): poly(4-styrenesulfonic acid) / single-walled carbon nanotubes (PEDOT: PSS/SWCNT, noted as PPSC) films to prepare ternary thermoelectric films of PEDOT: PSS/SWCNT/Ti 3 C 2 –Cl (PPSCT). The microscopic morphology, structures, and thermoelectric properties of PPSC and PPSCT films show that the introduction of Ti 3 C 2 –Cl results in a tendency of decreasing electrical as well as thermal conductivity , and the Seebeck coefficient is increased. When the content of Ti 3 C 2 –Cl reaches 8 wt%, the conductivity, Seebeck coefficient, and thermal conductivity of the PPSCT films reach the optimum values of 1683 S/cm, 21.69 μV/K, and 14.97 W/mK, respectively, and the power factor (PF) and thermoelectric figure of merit (ZT) are 79.23 μW/mK 2 and 1.58 × 10 –3 . The UPS and Hall effect results reveal that the improvement of the Seebeck effect of PPSCT mainly results from the ternary interfacial energy barrier as well as the change of carrier concentration. In addition, the wearable electronics devices demonstrate an output voltage of 4.5 mV and an output power of 54.36 nW under a 50 K temperature difference. The device displays a good monitoring sensitivity by reaching an output voltage of 0.6 mV at a 7 K temperature difference between the skin and the environment.

Background Triple-negative breast cancer (TNBC) has a high early recurrence rate and poor prognosis. Given its insensitivity to traditional systemic chemotherapy, there is an urgent need for new therapeutic strategies for effective treatment. This paper reports the development of a novel two-dimensional MXene composite nanoplatform for efficient synergistic chemotherapy and photothermal therapy of TNBC.Results To achieve surface functionalization of MXene, we developed a surface nanopore engineering strategy, enabling the uniform coating of a thin mesoporous silica layer on the two-dimensional Ti3C2 MXene surface. This strategy endows MXenes with well-defined mesopores for on-demand drug release/delivery and enhanced hydrophilicity/dispersibility. Systematic in vitro and in vivo evaluations demonstrate that Ti3C2@MSNs have high active targeting capability upon entering tumors, and through the synergistic chemotherapy of the mesoporous shell and the photothermal therapy of the Ti3C2 MXene core, tumors can be completely eradicated with no significant recurrence.Conclusion This study provides a new strategy for developing MXene-based composite nano drug delivery systems to effectively combat TNBC.

A novel electrochemical sensor based on titanium carbide (Ti 3 C 2 ) and cobalt porphyrin (CoTMPyP) nanocomposite was developed to detect catechol (CC). X-ray diffraction (XRD), transmission electron microscopy (TEM), energy-dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM) methods were used to characterize the CoTMPyP/Ti 3 C 2 nanocomposite and illuminate the electrochemical oxidation process, as well as electrochemical techniques such as electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and differential pulse voltammetry (DPV) were measured. The results indicate that the introduction of CoTMPyP greatly enhanced the electron transfer capability and maintained high stability, good reproducibility, and interference resistance. Moreover, it has a lower detection limit (2.5 μM) in the range of 5–268 μM and has greater application potential in the detection of CC. Hence, Ti 3 C 2 nanocomposites are considered as a candidate material for combination with carbon materials and have potential applications in environmental analysis and catechol detection.

For hydrogen evolution via overall water splitting, conveniently linked hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) catalysts are greatly sought. Thus, a three-step growth-conversion approach is used to create a particular type of Co2V2O6·2H2O/ZIF-L@MXene/NF in order to create a bifunctional water splitting catalyst. The strong coupling between Co2V2O6·2H2O/ZIF-L as a precursor to produce OER active species and a MXene that promotes mass/charge transfer greatly improves the performance of the catalyst. The as-prepared Co2V2O6·2H2O/ZIF-L@MXene/NF exhibits a low OER overpotential of 224 mV@50 mA cm−2, an HER overpotential of 98 mV@10 mA cm−2, and an overall water splitting overpotential of 1.478 mV@10 mA cm−2. To accomplish total water splitting, the electrolyser can also be powered by a solar cell (1.5 V). This research will help to create non-noble metal-based electrocatalysts that are effective and economical.

MXenes are a large class of two-dimensional (2D) materials widely studied recently since they have good water solubility and are able to tune the work function (WF) of materials without changing their electronic characteristics. Based on this, aqueous solution-processed indium-free zinc tin oxide (ZTO) thin-film transistors (TFTs) have been fabricated under an annealing temperature of 300 °C and successfully optimized. This optimization is achieved by fabricating a channel layer into a homojunction structure (MXene doped ZTO/ZTO) to form a two-dimensional electron gas (2DEG). Through doping the specific concentrations of Ti3C2Tx MXenes into the upper layer ZTO thin films, the TFTs exhibit enhanced field-effect mobilities (μFE) of 10.77 cm2 V−1 s−1 and 13.06 cm2 V−1 s−1 as well as a large on/off current ratio of more than 108. Moreover, compared with the undoped double-layer ZTO TFTs, the homojunction devices show better stability, mainly resulting from the transformation in leading conduction mode. Finally, through applying the homojunction channel on the solution-processed aluminum oxide (AlOx) dielectric layer, the μFE exhibits a further enhanced value of 28.35 cm2 V−1 s−1. This is the first report to apply MXenes to the channel layer of TFTs and to fabricate solution-processed ZTO thin films via an aqueous solvent under 300 °C.

Iodine intake remains a major public health concern, as both iodine excess and deficiency are related to adverse effects on health. Therefore, developing simple and economical methods to detect I − is still in great demand. Herein, we constructed a visual I − sensing platform based on the uncoated Ag–Ti 3 C 2 nanohybrids using methyl orange (MO) as a colorimetric indicator . Plasmonic nanostructures are frequently employed in colorimetric analysis , but uncoated Ag nanoparticles (NPs) are unstable because their surface energies are usually high. Considering that Ag NPs can be etched by I − via forming Ag–I bond, we introduce Ag–Ti 3 C 2 nanohybrids because uncoated Ag NPs with immaculate surfaces are more conducive to binding with I − and being etched. Dissolved O 2 molecules adsorbed on Ti 3+ of Ti 3 C 2 MXenes enable the in situ generation of H 2 O 2 by iodine-etching of uncoated Ag–Ti 3 C 2 nanohybrids. ∙OH radicals promote the degradation of MO through a self-driven Fenton-like process, exhibiting the color variation from orange to transparent. Under optimal conditions, the absorbance of MO at 465 nm decreases linearly with the concentration of I − in the range of 0.5–300 μM, with a limit of detection as low as 0.31 μM. This work opens the feasibility of iodine-etching of Ag in developing novel probes for facile colorimetric determination of I − .
