Thin-film interference with a Fabry–Pérot cavity is a classic approach to generating structural colors for anti-counterfeiting, sensors, and aesthetical demands. However, an absorbing layer capable of balancing the reflectance and absorption bands remains elusive, thereby limiting the chromatic and luminant tunability of structural coloration. Here wide-color-gamut films are reported with MXene as the absorbing layer in a simple trilayer configuration for vivid structural colors, outperforming conventional metal- and semiconductor-based films. It is demonstrated that the ‘lossy’ refractive indices of different metallic MXene compositions broaden the absorption bandwidth of multilayer films and maintain the high reflectance, enabling a substantial and complementary gamut with high tunability beyond the area of sRGB color space. Various structural color films/patterns based on MXenes showcase the compatibility for different scenarios. The results accompanied by theoretical calculations provide insights into the fundamental understanding of light-MXene interaction in coloration. The unique optical absorbance and solution processibility of the MXene family offer a versatile platform for the physical manipulation of light beyond conventional manufacturing approaches.

Bipolar membrane electrodialysis (BMED) efficiently transforms salts into acids and bases, with bipolar membranes (BPMs) playing a pivotal role. This study pioneers high-performance BPMs via a layer-by-layer casting/spraying technique, incorporating sulfonated polysulfone cation-exchange layers, polydopamine-modified MXene (PDA-Ti 3 C 2 T X ) interfacial layers, and quaternized polyphenylene oxide anion-exchange layers. PDA-Ti 3 C 2 T X exhibits remarkable catalytic activity, promoting water dissociation. The BPMs exhibit exceptional interfacial compatibility, alkali resistance, and long-term durability. At 80 mA · cm −2 , the BPMs manifest reduced transmembrane voltages (1.54 ∼ 2.80 V) compared to control samples (Blank BPM: 7.70 V; 0.75 %-Ti 3 C 2 T X -BPM: 5.51 V). Post-BMED salt conversion, the 1.00 %-PDA-Ti 3 C 2 T X -BPM displays the lowest final voltage drop (9.9 V), akin to the commercial SSBP-1 (9.8 V). The 0.75 %-PDA-Ti 3 C 2 T X -BPM attains the highest OH – concentration (0.094 mol·L -1 ) and current efficiency (98.79 %), surpassing SSBP-1 (0.090 mol·L -1 , 94.47 %). The BPMs demonstrate superior energy consumption (2.00 ∼ 2.49 kWh kg −1 ) compared to SSBP-1 (2.94 kWh kg −1 ). This investigation delineates efficient and stable BPMs for BMED applications.

In this study, Ti 3 C 2 MXene nanofragments with a size distribution of about 20 nm were laden on the well-characterized bacteriophages via electrostatic bonding , introducing a new antibacterial agent as a modified virus vector to be used in high-risk bacterial environment. At > MIC of MXene, the MXene-functionalized bacteriophage would be much more active in attacking the bacteria because of the high specificity for host receptors’ recognition and targeting ability of bacteriophage and bacterial surface negative charge when comparing to the phage alone. Also, the induced positive surface moieties drive MXene nanofragments toward the negative surface charge of bacteria. The main mechanisms are the specific targeting capacity of bacteriophages, often by lysing the host and bursting out, and the physical interaction of MXene nanofragments with the bacterial cell membrane, which may rupture the cell wall in microbial death. The results described that the Ti 3 C 2 MXene significantly enhanced the bacteriophage adsorption rate and stability over long-standing cultivation in aquatic environments providing superior antibacterial efficacy against the bacterial cells target. The Ti 3 C 2 MXene-laden bacteriophage demonstrated a fast, efficient attaching to bacterial host cells, high antibacterial potential, and reduced 99.99% of the artificial contamination in water samples. Interestingly, no re-growth of target bacteria was observed in the samples during the experiment period, and the count of bacteria constantly remained below the detection threshold. This research raises attention in proposing a novel antibacterial agent to be synthesized through a simple one-step technique devoid of shortcomings of post-treatments in conventional antibacterial treatments.

Hydrogen fuel has been embraced as a potential long-term solution to the growing demand for clean energy. A membrane-assisted separation is promising in producing high-purity H 2 . Molecular sieving membranes (MSMs) are endowed with high gas selectivity and permeability because their well-defined micropores can facilitate molecular exclusion, diffusion, and adsorption. In this work, MXene nanosheets intercalated with Ni 2+ were assembled to form an MSM supported on Al 2 O 3 hollow fiber via a vacuum-assisted filtration and drying process. The prepared membranes showed excellent H 2 /CO 2 mixture separation performance at room temperature. Separation factor reached 615 with a hydrogen permeance of 8.35 × 10 −8 mol·m −2 ·s −1 ·Pa −1 . Compared with the original Ti 3 C 2 T x /Al 2 O 3 hollow fiber membranes, the permeation of hydrogen through the Ni 2+ -Ti 3 C 2 T x /Al 2 O 3 membrane was considerably increased, stemming from the strong interaction between the negatively charged MXene nanosheets and Ni 2+ . The interlayer spacing of MSMs was tuned by Ni 2+ . During 200-hour testing, the resultant membrane maintained an excellent gas separation without any substantial performance decline. Our results indicate that the Ni 2+ tailored Ti 3 C 2 T x /Al 2 O 3 hollow fiber membranes can inspire promising industrial applications.

Lithium, an emerging mineral of critical global significance, is recognized as a strategic resource by major economies worldwide, leading to an increased demand for this essential element. The extraction of lithium from rich sources, such as seawater and brine, has become commonplace. Among various liquid lithium extraction techniques, the lithium-ion sieve (LIS) adsorption method has attracted substantial attention owing to its simplicity, high recovery rate, and relatively low energy consumption. Despite significant advancements in LIS technology, the powdery nature of these materials poses challenges to handling and recycling, leading to inevitable adsorbent loss and limited practical applications. LISs are typically recycled through powder shaping, but the commonly employed shaping methods may result in a reduction in the adsorbent’s adsorption capacity. Therefore, it is urgent to develop a technology that can not only realize the recycling of LISs but also avoid the loss of the adsorbent’s adsorption capacity. We synthesized a titanium-based LIS (HTO) hybrid membrane by incorporating 2D MXene, known for its excellent properties across various applications. The incorporation of MXene into the membrane significantly increased the pore structure, enhancing adsorption site exposure and facilitating Li + migration. The HTO/MXene@PVC hybrid film demonstrated favorable adsorption properties, with an Li + adsorption capacity of 25.4 mg·g −1 within 24 h. Additionally, the film exhibited notable selectivity capacity and maintained its adsorption capacity above 90 % even after eight adsorption–desorption cycles, indicating excellent cycling performance. This study introduces a novel design concept for adsorbents, specifically for extracting Li + from liquid lithium sources, offering new insights for the development of Li + adsorbents aimed at enhancing lithium recovery.

As a typical hetero-MXene, Ti 3 CN MXene has attracted great attentions owing to its ultrafast carrier dynamic and unique nonlinear optical response. However, the photo-response of pristine Ti 3 CN is unsatisfied due to the fast carrier recombination. Herein, multi-layer Ti 3 CN MXene is modified with well-dispersed Bi quantum dots, where the Ti 3 CN@Bi heterojunction can not only tune the optical absorption but also introduce energy transfer channels. The built-in electric field endows Ti 3 CN@Bi self-powered response behavior and the performance can be further enhanced by tuning external conditions. As demonstrated, the Ti 3 CN@Bi-based photodetectors exhibit high photocurrent density (18.24 µA cm −2 ) and excellent photoresponsivity (18.32 mA W −1 ). In addition, the device shows fast response and outstanding stability (0.002% for each cycle), holding great potentials for practical applications. Hence, this work not only highlights the broad prospects of MXene-based heterojunction, but also provides great value for other optoelectronic device applications.

Photocatalytic technology with high oxidative activity has been considered promising for eliminating fouling of nanofiltration (NF) membranes when used in organic pollutant removal. Herein, we report a photocatalytic self-cleaning NF membrane composed by two dimensional Ti 3 C 2 T x MXene and NaTaO 3 nanoparticles with excellent permeability and antibiotics removal efficiency. Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) were used to verify the successful preparation of the photocatalytic self-cleaning membrane. The membrane with the NaTaO 3 nanoparticles loading of 8 mg (NM-8) exhibited excellent rejection (>99.67%) and water permeability (90.79–112.50 L m −2 h −1 ·bar −1 ) for tetracycline hydrochloride (TC), ciprofloxacin (CIP), methylene blue (MB), and 2-mercaptobenzothiazole (MBT). The removal efficiencies of the membrane for TC, CIP, MB, and MBT during the photocatalytic degradation process were 75.18%, 70.13%, 90.04% and 93.12%, respectively. Moreover, the chemical and optical properties were investigated by zeta potential, water contact angle, and UV–vis spectrum. The mechanism of photodegradation of pollutants by the prepared NaTaO 3 @Ti 3 C 2 T x MXene membranes was further elucidated. This work not only deepens the construction of photocatalytic NF membranes using two dimensional materials, but also provides a new strategy for the efficient removal of antibiotics from wastewater.

Two-dimensional layered material of Ti 3 C 2 has been used to improve the hydrogen desorption properties of LiBH 4 . The results of temperature-programmed dehydrogenation (TPD) and isotherm dehydrogenation (TD) demonstrate that adding the Ti 3 C 2 contributes to the hydrogen storage performance of LiBH 4 . The dehydrogenation temperature decreases and the dehydrogenation rate increases with increasing the adding amounts of Ti 3 C 2 . The onset dehydrogenation temperature of LiBH 4 + 40 wt% Ti 3 C 2 composite is 120 °C and approximately 5.37 wt% hydrogen is liberated within 1 h at 350 °C. Furthermore, the activation energy of LiBH 4 + wt.% Ti 3 C 2 is also greatly reduced to 70.3 kJ/mol, much lower than that of pure LiBH 4 . The remarkable dehydrogenation property of the LiBH 4 + 40 wt% Ti 3 C 2 may be due to the layered active Ti-containing Ti 3 C 2 and the high surface area of MXene .

MXenes have emerged as promising electrode materials for supercapacitors based on their metallic conductivity, good hydrophilicity, rich surface chemistry, and excellent mechanical characteristics. However, the strong interlayer van der Waals forces induce significant layer restacking, which restrict complete exposure of MXenes’ surface active sites, impeding electron/ion transport and resulting in poor electrochemical performances. Herein, a porous MXene/carbon nanotube (CNT) film was prepared through a simple alkali-induced process. The developed porosity and the introduction of CNTs can effectively suppress the restacking of MXene nanosheets, promoting the effective utilization of the surface active sites of the MXene and facilitating fast ion/electron transportation. Consequently, the porous MXene/CNT film exhibited a high specific capacitance of 401.4 F g–1 at 1 A g–1 and a sustained capacitance of 336.2 F g–1 at an ultrahigh current density of 1000 A g–1, corresponding to an 83.8% capacitance retention. Furthermore, the film electrode demonstrated outstanding cycling stability, with a capacitance retention of 99.0% after 20,000 cycles at 100 A g–1, showing its significant potential for supercapacitor applications.

Phosphorus-nitrogen intumescent flame retardant (IFR) is one of the most promising halogen-free flame retardants in enhancing the fire safety of polypropylene (PP), but its efficiency needs to be further improved. Herein, a novel single-component polyphosphazene IFR containing pentaerythritol caged phosphate (PEPA) functionalized titanium carbide nanosheet (MXene), named PZS-MXene, was prepared. When the amount of PZS-MXene was 25 wt%, PP/PZS-MXene classed a UL-94 V-0 rating with the limiting oxygen index of 32.7%. Compared with PP, its peak of heat release rate, total heat release rate and total smoke production rate were reduced by 74.5%, 33.0%, and 19.8%, respectively. The flame-retardant mechanism revealed that PZS-MXene quenched high-active free radicals to inhibit the degradation of PP during the combustion. MXene rapidly catalyzed the carbonization of PZS to form high-quality intumescent char layer on its surface. Besides, MXene acted as the supporting skeletons and exerted the layered barrier effect to improve the compactness of the intumescent char layer, thus effectively inhibited the degradation and combustion of PP. This work provided new insights for the efficient halogen-free flame-retardant PP.

Increasing the efficiency of charge transfer and separation efficiency of photogenerated carriers are still the main challenges in the field of semiconductor-based photocatalysts. Herein, we synthesized g-C 3 N 4 @V 2 C MXene photocatalyst by modifying g-C 3 N 4 using V 2 C MXene. The prepared photocatalyst exhibited outstanding photocatalytic performance under visible light. The degradation efficiency of methyl orange by g-C 3 N 4 @V 2 C MXene photocatalyst was as high as 94.5%, which is 1.56 times higher than that by g-C 3 N 4 . This was attributed to the V 2 C MXene inhibiting the rapid recombination of photogenerated carriers and facilitating rapid transfer of photogenerated electrons (e − ) from g-C 3 N 4 to MXene. Moreover, g-C 3 N 4 @V 2 C MXene photocatalyst showed good cycling stability. The photocatalytic performance was higher than 85% after three cycles. Experiments to capture free radicals revealed that superoxide radicals (·O 2 − ) are the main contributors to the photocatalytic activity. Thus, the proposed g-C 3 N 4 @V 2 C MXene photocatalyst is a promising visible-light catalyst.
