In pursuing efficient photocatalytic systems, nature-inspired photocatalysis has emerged as a promising strategy to optimize charge transfer and surface reactions. Inspired by the structure and function of plant leaves, a leaf-like hierarchical heterostructure is constructed. ZnIn 2 S 4 nanosheet arrays are anchored on the integrated Ag nanowires network with Ti 3 C 2 T x MXene support, during which process sulfur vacancies (V S ) are formed due to the anti-strong metal-support interaction. The ZnIn 2 S 4 nanosheet arrays supported by Ti 3 C 2 T x serve as mesophyll to absorb photons and convert solar-to-chemicals, the Ag nanowires embedded in the interface of ZnIn 2 S 4 and Ti 3 C 2 T x function as veins to shuttle the charge carriers for the surface redox reactions, and the V S on ZnIn 2 S 4 resemble stomata to facilitate the adsorption of reactants. Furthermore, the formed V S are able to reduce the thermodynamic barriers in photocatalytic reactions. The synergistic effect of these functional components enables hydrogenation of several nitroaromatic compounds, and exhibits a photocatalytic H 2 evolution rate of 1119.4 µmol g⁻¹ h⁻¹ under visible-light irradiation, which is ≈7.9 times as high as that of pure ZnIn 2 S 4 . This study highlights the pivotal role of functional design inspired by nature in advancing solar-to-chemical conversion and paves the way for the development of next-generation photocatalysts in green chemistry and H 2 energy applications.

A dual-mode (colorimetric/electrochemical) aptasensor was developed for ZEN detection. • Au@Ti 3 C 2 T x MXene@MoSe 2 was synthesized to enhance electrode conductivity and surface area. • RCA was integrated to generate G-quadruplexes for both electrochemical and colorimetric readouts. • Electrochemical mode achieved 1.23 fg/mL LOD; colorimetric mode enabled convenient visual screening. • The sensor exhibited excellent selectivity, stability, and recoveries (89.6–106.2%) in real samples. Zearalenone (ZEN), a nonsteroidal mycotoxin produced by Fusarium fungi, widely contaminates cereals and their derived products, posing a serious threat to human health. In this study, a highly sensitive dual-mode (colorimetric and electrochemical) aptasensor for ZEN was constructed. The sensor employs rolling circle amplification (RCA) to efficiently generate long single-stranded DNA rich in G-quadruplex sequences, combined with an electrode modified with an Au@Ti 3 C 2 T x MXene@MoSe 2 nanocomposite, thereby achieving synergistic signal amplification and dual readout. In the electrochemical mode, the RCA product is anchored through hybridization between the primer and the capture probe on the electrode surface, where it adsorbs abundant methylene blue to produce a square wave voltammetry (SWV) response. In the colorimetric mode, the G-quadruplex structures self-assemble with hemin to form peroxidase-mimicking DNAzymes, which catalyze the TMB chromogenic reaction to generate a visual signal. Experimental results showed that the electrochemical mode achieved a detection limit as low as 1.23 fg/mL (detection range: 10 −3 -10 4 pg/mL), while the colorimetric mode exhibited a detection limit of 64.89 fg/mL (detection range: 1 pM-10 μM). The aptasensor demonstrated excellent selectivity, good stability, and satisfactory reproducibility for ZEN, with spiked recoveries ranging from 89.6% to 106.2% in real corn flour and beer samples. This dual-mode sensing platform effectively eliminates single-mode interferences through signal cross-validation, providing a reliable technical means for the accurate and rapid detection of trace ZEN in food safety.

Incorporating nanomaterials for a thin film nanocomposite (TFN) layer has been verified effective to improve the separation performance of nanofiltration (NF) membranes, whereas the poor compatibility between nanomaterials and polyamide (PA) matrix leads to a decrease in the salt rejection and pollution resistance. In this study, inspired by a new interface-bridging idea, Ti 3 C 2 T x was bonded with tannic acid-Fe(III) (TA-Fe(III)) complexes, and then incorporated into a PA matrix for the first time to obtain a novel TFN NF membrane. The introduction of TA-Ti 3 C 2 T x was found to effectively reduce the diffusion of piperazine, and thus result in the induction of a thinner, lower roughness, more hydrophilic, and defect-free PA layer. With the addition of 0.015 wt% TA-Ti 3 C 2 T x , the TFN membrane obtained the highest water permeability of 12.17 L m −2 h −1 bar −1 , almost twice that of the pristine membrane, with a high Na 2 SO 4 rejection above 97 %. In addition, the TA-Ti 3 C 2 T x -filled TFN membranes were verified to exhibit excellent antifouling performance and pressure resistance with a high durability, which is crucial for the practical application in salinity water treatment. This study provides an effective strategy to tailor the interfacial microstructural of nanoparticle-filled NF membranes for superior divalent-salinity-water separation.

Assembling two-dimensional (2D) MXene nanosheets into monolithic three-dimensional (3D) structures is an efficient pathway to transfer the nanoscale properties to practical applications. Nevertheless, the majority of the preparation schemes described in the literature are carried out at relatively high temperatures, which inevitably leads to the notorious high-temperature oxidation issue of MXenes. Preparing MXene-based hydrogels at lower temperatures or even room temperature is of great research importance. In this study, we report a novel and efficient room-temperature gelation method for fabricating 3D macro-porous Ti 3 C 2 T x MXene/reduced graphene oxide (RGO) hybrid hydrogels, using anhydrous sodium sulfide (Na 2 S) as the primary reducing agent and l -cysteine as the auxiliary crosslinker. This room-temperature preparation technique successfully prevents the oxidation issue of MXenes and generates porous aerogels with excellent structural robustness after freeze-drying. As the self-standing anode for sodium-ion storage, the optimized 3D Ti 3 C 2 T x MXene/RGO electrode possesses a specific capacity of 152 mAh/g at 0.1 A/g and good cycling stability with no significant capacity degradation after 500 cycles, which is significantly higher than that of the vacuum-filtered MXene film. This work demonstrates a straightforward room-temperature gelation method for constructing 3D MXene-based hydrogels to avoid the oxidation of MXenes, and casts new insight on the mechanism of the graphene oxide (GO)-assisted gelation.

Ti3C2Tx MXene has a high specific surface area and high conductivity, and can be used in the field of humidity sensing. By controlling the surface termination and microstructure of the material, it is expected to improve the humidity sensing performance of Ti3C2Tx MXene. In this paper, we report a method of electrolytic intercalation treatment of Ti3C2Tx MXene in NaOH solution. Theoretical and experimental results show that this method can remove the original F terminations from the surface of Ti3C2Tx MXene and form a large number of OH and O terminations. The partial oxidation of the surface and the replacement of terminations and the insertion of Na+ lead to the change of the Ti3C2Tx MXene layer morphology from flat to curly and significantly improve the hydrophilicity and resistance. The curly flake structure constructs a fast channel for the entry and exit of water molecules which improves the hydration/dehydration efficiency of the material; the enhanced hydrophilicity of the material sharply reduces the resistance of the material after moisture absorption, which significantly improves the responsiveness of Ti3C2Tx MXene to humidity. The curly flake Ti3C2Tx MXene humidity sensor has an ultra-high sensitivity of S = 1.2 × 105 (two orders of magnitude higher than that of the reported humidity sensor based on MXene), with a fast response rate (2 s), good repeatability and stability (4 weeks), and it can be used for the analysis of human respiration rate, and also for non-contact sensing detection of the human body and environmental humidity detection.

Gold nanorods (Au NRs)/Ti 3 C 2 T x composites were prepared by self-assembly method as surface enhanced Raman scattering (SERS) substrates. Due to strong electrostatic interaction , Au NRs are evenly arranged on the surface of Ti 3 C 2 T x nanosheets , forming rich SERS hotspots. Au NRs/Ti 3 C 2 T x have high sensitivity and good reproducibility for the determination of organic dyes such as rhodamine 6G, crystal violet and malachite green. The detection limits were 1 × 10 −13 , 1 × 10 −13 and 1 × 10 −12 M, respectively. The relative standard deviations of samples in 40 areas were 4.57 %, 2.79 % and 3.47 %, respectively. The synthesized SERS substrate is sensitive to adenine. For adenine molecules in the range of 1 × 10 −5 –1 × 10 −9 M, SERS results show that the peak intensity is linear with adenine molecular concentration, and the detection limit can be as low as 1 × 10 −9 M. In addition, adenine in aqueous solution has good anti-interference ability to other nucleic acids with similar structure, such as guanine, cytosine and thymine. Therefore, Au NRs/Ti 3 C 2 T x are expected to become a potential substrate for unmarked, rapid and sensitive SERS detection of adenine in the field of bioanalysis.

To conquer the trade-off dilemma of the nanofiltration membranes for both high permeability for water and high rejection for pollutants has long been highly concerned. In this work, TiO 2 and Bi 2 S 3 nanoparticles were evenly dispersed successively into the interlayers of Ti 3 C 2 T x nanosheets, and then filtered onto cellulose acetate support membranes. The as-obtained composite membranes exhibited a maximum water flux of 374.4 L m −2 h −1 bar −1 , and a high rejection ratio for RhB, GR, MB and BSA at 97.8–100%, apparently higher than those of the Ti 3 C 2 T x and the related membranes in literature. Such a high separation capacity was found quite stable for various dye-containing aqueous solutions, even in a high salinity environment of 5 wt% NaCl. Interestingly, 25% NaCl salt was also rejected accompanying the almost complete rejection of dye pollutants. After the filtering process, the membrane fouling of fouled Ti 3 C 2 T x /TiO 2 /Bi 2 S 3 membranes was verified quite lower than that of fouled Ti 3 C 2 T x /TiO 2 and Ti 3 C 2 T x membranes. Furthermore, the flux recovery rate of the fouled composite membrane could reach 92.1% after washing under visible light, which could be ascribed to the composition of heterojunction causing the red shift of diffuse reflectance UV–vis spectra and the narrowing of the band gap. This study provides a new idea for the preparation of highly permeable and rejective nanofiltration membranes, and lays a foundation for its high-capacity dye removal applications.

Wearable heaters have attracted growing attention for maintaining a relatively constant temperature of the human body in cold environments with near zero energy consumption. Herein, we developed a multifunctional laminated fabric with fascinating electro/solar-thermal conversion, thermal energy storage and thermal insulation properties. With cotton fabric as the substrate, MXene/polydimethylsiloxane (PDMS) conductive network was decorated on the upper layer, and carbon nanotube (CNT)/cellulose nanofiber (CNF)/paraffin (PA) aerogel phase change composites were assembled on the bottom layer. Attributed to the strong conductivity and light absorption of MXene and the light/thermal response of CNT and PA components, this wearable laminated fabric broke the limitation of intermittent solar photothermal heating, and integrated multiple heating modes to precisely heat the human body. Meanwhile, the low thermal conductivity of aerogel retarded heat loss. The laminated fabric can help people better adapt to a variety of complex and changeable environments such as cold winter, rainy days and nights. This study provides a promising and energy-efficient avenue for the development of all-day personal thermal management fabrics.

Exploring an efficient and stable adsorbent material for purification of toxic heavy metal ions wastewater is of great significance. However, as a typical heavy metal ions adsorbent, titanate can still improve in material synthesis, adsorption efficiency and the recyclability . Herein, a novel titanate-based adsorbent which composing of Ti 3 C 2 T x MXene-derived hydroxy-rich titanate and cellulose was fabricated for efficient removal of toxic heavy metal ions. Owing to the similar stratified structure, the conversion from Ti 3 C 2 T x MXene to titanate is energy-saving and easy to achieve. In addition, the inherited hydroxy-rich property is beneficial to improve the adsorption efficiency of the derived titanate. Furthermore, the introduction of cellulose as a structural regulator to fabricate the titanate/cellulose membrane could greatly alleviate the problem of difficult recycling of powder adsorbent. Thus, the constructed Ti 3 C 2 T x -derived hydroxy-rich titanate/cellulose membrane adsorbent (M-NTO/CM) exhibits high Cu 2+ adsorption capacity of 2.63 mmol g −1 and can reach the adsorption equilibrium in only 5 min. Better yet, there has also been a significant improvement in acid resistance and recyclability of the M-NTO/CM relative to traditional titanate. In short, M-NTO/CM derived from Ti 3 C 2 T x MXene can be used as an advanced membrane for convenient and efficient purification of heavy metal ions from the wastewater.

Photothermal conversion behavior has a vital application to disease therapy, water purification, or uncontacted heaters. The fabrication of high-performance photothermal conversion materials especially for near-infrared (NIR) light and microstructures has attracted a great deal of attention. Among numerous substances, MXene as a new type of 2D material with semi-metallic and unique electromagnetic properties presents a broader absorption of light and even a typical plasmonic absorption near the NIR-I area (808 nm), which has made it suitable for photothermal conversion. Here, we propose a facile approach for preparing a Ti3C2Tx/ionic liquid ink with a high photothermal conversion efficiency. The as-prepared ink has showed good wettability of various substrates as well as the high sensitivity of 808 nm NIR light irradiation and a wide range of thermal variation. After packing the ink into a gel pen refill, the flexible thermal chips could be easily obtained just by pen writing on the soft surface with the designed size, which also have become an optimal candidate for the thermal alarm system.

The porous structure of three-dimensional NiO microspheres on titanium carbide (NiO/Ti 3 C 2 T x ) is prepared by calcination of Ni-MOF/Ti 3 C 2 T x in the air. The crystalline structure and morphology of the obtained hybrid are characterized with various tools such as X-ray photoelectron spectroscopy and X-ray diffraction, scanning electron microscope, transmission electron microscope, and Brunauer-Emmett-Teller surface analyzer techniques. As-prepared NiO/Ti 3 C 2 T x hybrid is used for two noteworthy applications in electrochemistry like supercapacitor and non-enzymatic hydrogen peroxide (H 2 O 2 ) sensor. NiO/Ti 3 C 2 T x electrode exhibited an enhanced specific capacity of 630.9C g −1 at a current density of 1 A g −1 in comparison to pure NiO (376.8C g −1 ). Furthermore, the H 2 O 2 sensing performance of the NiO/Ti 3 C 2 T x modified glassy carbon electrode is evaluated in 0.5 M of NaOH solution and the electrode showed a low detection limit of 0.34 μM with a wider range of linear response 10 μM to 4.5 mM. The higher specific surface area and porosity of NiO/Ti 3 C 2 T x allow more electro-active site for electrochemical redox reactions in the direction of H 2 O 2 sensing and supercapacitor. Moreover, Ti 3 C 2 T x prevents from fouling in 3D porous network and leaching effect, and beneficial for easy access of electrolyte ions and efficient electron transport to the electrode surface resulted in improved electrochemical applications.

Synthesis of fluorescent carbide-derived carbons (CDCs) remains a big challenge for material scientists. Herein, we report an unprecedented method for the synthesis of amphiphilic carbide-derived graphene quantum dots (GQDs) from layered Ti 3 C 2 T x MXene using solvothermal treatment of Ti 3 C 2 T x MXene in dimethylformamide (DMF). Our findings indicate that DMF can simultaneously act as reaction media and nitrogen-doping agent for the formation of highly fluorescent carbide-derived GQDs. The resulted GQDs with uniform size distribution exhibit excellent dispersibility in both hydrophilic solvents (e.g., water, DMF, and ethanol) and in hydrophobic solvents (e.g., chloroform and toluene). With their superior properties of bright and tunable photoluminescence , low cytotoxicity, good photostability and chemical inertness , the carbide-derived GQDs are promising for applications in fluorescent ink, light-emitting composites and cellular imaging as demonstrated in this paper. This work opens a new route towards the large-scale synthesis of high-quality GQDs, paving the way for their versatile applications.
