The photocatalytic conversion of biomass utilizing two-dimensional (2D) MBene as co-catalyst represents an exemplary approach for the sustainable production of syngas and lactic acid, capitalizing on the renewable resources of biomass carbon and solar energy. In this study, CrB MBene was synthesized via in-situ exfoliation in an HCl aqueous solution and subsequently integrated with Cd 0.8 Zn 0.2 S through an in-situ growth strategy, aiming to facilitate the photocatalytic co-production of lactic acid and syngas. Notably, the CZS/CrB-10 variant demonstrated a remarkable 12.3-fold enhancement in the hydrogen evolution rate (1746.6 μmol g −1 h −1 ) compared to standalone Cd 0.8 Zn 0.2 S, highlighting the exceptional co-catalytic efficiency and air stability of CrB MBene. Under optimal experimental conditions, the lactic acid yield and CO evolution rate attained 75.4 % and 917.8 μmol g −1 h −1 , respectively. The incorporation of CrB MBene as a co-catalyst was found to significantly improve sunlight utilization, enhance the separation and transfer of photogenerated charge carriers, and mitigate the recombination of electrons and holes. This research underscores the potential of CrB MBene as a promising and cost-effective co-catalyst, with implications for advancing artificial photosynthetic systems and the integration of photocatalytic biomass refining with water splitting technologies.

The intercalation of organic molecules is a promising approach to modulate the structure of 2D transition metal borides (MBenes), aiming to enhance charge transport and improve electrochemical performance in energy storage applications. However, key questions remain regarding how organic molecules with diverse functionalities penetrate and align between the MBene layer, as well as the mechanism of charge redistribution during intercalation. Addressing these questions is crucial for guiding the design of Organic-MBene heterostructures. To this end, a comprehensive approach combining theoretical calculations and experimental analyses was employed to explore the self-assembly mechanisms of organic molecules featuring N, O, S and tertiary amine end groups on the MoB-MBene surface. Experimental characterizations confirm that the interaction between MoB and organic compounds depends on the end groups. First principles calculations demonstrate that organic molecules tend to adopt a flat configuration on the MoB surface during molecular assembly. Calculations also reveal that the binding and charge transfer processes from organic molecules to MoB are highly dependent on the specific end groups, consistent with experimental observations. Furthermore, the effect of combining organic molecules with MoB on battery performance was further discussed, offering new insights for advancing the research and development of MBenes in aqueous battery systems.

Highly active and low-cost co-catalysts have a positive effect on the enhancement of solar H2 production. Here, we employ two-dimensional (2D) MBene as a noble-metal-free co-catalyst to boost semiconductor for photocatalytic H2 production. MoB MBene is a 2D nanoboride, which is directly made from MoAlB by a facile hydrothermal etching and manual scraping off process. The as-synthesized MoB MBene with purity >95 wt % is treated by ultrasonic cell pulverization to obtain ultrathin 2D MoB MBene nanosheets (∼0.61 nm) and integrated with CdS via an electrostatic interaction strategy. The CdS/MoB composites exhibit an ultrahigh photocatalytic H2 production activity of 16,892 μmol g–1 h–1 under visible light, surpassing that of pure CdS by an exciting factor of ≈1135%. Theoretical calculations and various measurements account for the high performance in terms of Gibbs free energy, work functions, and photoelectrochemical properties. This work discovers the huge potential of these promising 2D MBene family materials as high-efficiency and low-cost co-catalysts for photocatalytic H2 production.

Phthalates are a class of widely used endocrine-disrupting chemicals, presenting substantial health hazards upon their release into aquatic environments. Herein, the catalytic potential of two-dimensional transition metal borides (MBenes, including Fe 2 B 2 , MnB, MoB, and Mo 1.33 B) as co-catalysts for activating diverse peroxides in Fenton/Fenton-like oxidation processes, with particular emphasis on optimizing the Fe(III)/Fe(II) cycling efficiency. Under optimized conditions, the Fe 2 B 2 /hydrogen peroxide (H 2 O 2 ) system demonstrated superior catalytic performance, achieving complete degradation of dimethyl phthalate (DMP) within 15 min. This system exhibited pseudo-first-order rate constants that were 5.7–154.3 times higher than those of other MBenes/Fe(III)/H 2 O 2 systems, highlighting its exceptional catalytic efficiency. Notably, Fe 2 B 2 exhibited exceptional stability through five consecutive cycles, maintaining DMP degradation rates (∼100 %) with minimal boron leaching (∼1.05 mg/L). Mechanistic studies revealed a dual activation pathway. Surface-bound Fe(II) species decompose H 2 O 2 directly to produce hydroxyl radicals. Meanwhile, B–Fe–B bridges facilitate Fe(II) regeneration by transferring electrons from iron atoms or B B bonds in Fe 2 B 2 to dissolved FeOH 2+ species. This synergistic interaction establishes a self-sustaining catalytic cycle that significantly enhances the Fenton reaction kinetics. These findings establish Fe 2 B 2 MBene as dual-functional material that serves as both a sustainable dual-function catalyst and an efficient iron source, providing new perspectives for designing MBene-based catalysts for environmental remediation applications.

Solar-driven interfacial steam generation (SISG) is a promising cutting-edge technology for addressing challenges related to water scarcity and environmental issues. Solar-to-heat conversion is essential for this technology and highly relies on photothermal materials. Herein, we present a new class of two-dimensional (2D) layered photothermal materials, namely 2D transition metal boride MBene, to integrate thermally insulated nylon membrane to create SISG evaporator for solar steam generation. The MBene membrane gains broadband light absorption, effective heat localization and rapid water transport, which exhibits excellent solar steam generation performance with a high evaporation rate of 1.59 kg m -2 h −1 and efficiency as high as 96.66 % under one-sun irradiation. Significantly, the MBene membrane displays favorable robustness and flexible applications in steaming various contaminated wastewater sources (e.g. organic dyes, antibiotics, oil–water emulsions, heavy metal and acidic/alkaline solutions) at high rejection efficiency and outstanding durability. Meanwhile, the sustainable production of high-quality freshwater through solar desalination of seawater and brine solutions can be also achieved over this SISG system. The present study demonstrates a new photothermal conversion capability of MBene-based materials and its great potential in SISG applications.

Transition metal oxide CoO has attracted extensive attention as a potential anode material for lithium-ion batteries (LIBs) due to its impressive theoretical specific capacity. However, pristine CoO often suffers from structural collapse during cycling, resulting in reduced capacity. To address these challenges, we developed a method to in situ grow octahedral CoO nanoparticles on hierarchical multilayer MoB MBene. The matched layer gradients and heterojunction formation between CoO and MoB MBene effectively accommodate the volume expansion of CoO. Following 200 cycles at 100 mA/g, the CoO/MoB MBene electrode achieves a capacity of 819.8 mAh/g, a significant 2.58-fold performance improvement over pristine CoO. Even at 1000 mA/g, the composite retains a capacity of 601.3 mAh/g after 600 cycles, while the pristine material retains only 142.4 mAh/g. This breakthrough suggests CoO/MoB MBene composite holds great promise in improving the performance of LIBs and may pave the way for the development of advanced materials.

High rate tolerance and long cycle life represent the critical demand of the market for energy storage devices, known as one of major challenges for the development of rechargeable aqueous batteries. Herein, a layered Mo4/3B2T2 (where “T” denotes -O, -OH, and -F terminations) MBene (a transition metal boride) with in-plane ordered metal vacancies is first proposed as an iodine species host of an aqueous Zn‖I 2 battery, delivering a discharge capacity of 106.8 mAh g −1 at 25 A g −1 after 230 000 cycles and 80 mAh g −1 at 100 A g −1 , far exceeding those of all Zn‖I 2 batteries ever reported. The high performance is attributed to the strong affinity with iodine species and accelerated the redox kinetics by the conductive MBene with metal vacancies, as evidenced by the one-step conversion of I ‒ /I 0 without the generation of I 3‒ ions. This work unlocks a new route for the construction of other halide or sulfur electrode batteries with superior durability and kinetics.

Lowering the threat of antibiotics is a hot issue in environmental chemistry. To overcome this problem, a novel MBene-based adsorbent, DTT@BC@MoBT x , was designed by modification of bacterial cellulose (BC) using MoBT x MBene and 1,4-dithiothreitol (DTT). Several characterization methods, including Fourier transforms infrared (FTIR), X-ray photoelectron spectroscopy (XPS), and X-ray Diffraction (XRD), confirmed the successful synthesis of DTT@BC@MoBT x composite. It was discovered that the abundance of functional groups, higher specific surface area, and porosity were facilitative for DTT@BC@MoBT x adsorbents to indomethacin (IDM) and losartan (LP). The adsorption of IDM and LP well fitted to the pseudo-second-order kinetic model and Langmuir isotherm model, suggesting the single-layer chemisorption occurred on the adsorbent. The maximum sorption capabilities of the DTT@BC@MoBT x adsorbent were 1041.26 mg/g for IDM and 887.31 mg/g for LP, indicating excellent adsorption performance. The adsorption capacities of IDM and LP showed a slight decline after four consecutive adsorption-desorption tests, indicating excellent regeneration ability and stability. Interfering monoanionic (Na + and K + ) and monoanionic (Cl − and NO 3 − ) exhibited negligible impacts on IDM and LP elimination rates at all three concentrations. Additionally, it was discovered that metal ions had a greater ability for interference in a higher valency state (Mg 2+ , Ca 2+ , SO 4 2− , and CO 3 2− ) than in a lower valency state (Na + , K + , Cl − , and NO 3 − ). The adsorption processes of IDM and LP by the DTT@BC@MoBT x adsorbent involved hydrogen bonding and electrostatic attraction, as shown by FTIR and XPS analyses. This work offered a novel MBene-based adsorbent for the quick and effective adsorption of IDM and LP from water.

The measurement of fluctuations in the kinetic levels of the dopamine signal is important for the detection of the body's endocrine response to stressful stimuli. However, traditional dopamine measurements are prone to damage, while the stability of existing wearable sensors needs to be improved. To address this, a non-invasive, self-cleaning, and stretchable and flexible electrochemical sensor patch (i.e., sCMZ sensor) has been presented for a non-invasive, rapid, simple, and highly sensitive long-term and stable monitoring of dopamine levels in biofluids. Subsequently, an innovative “zipper” synthesis strategy was employed to successfully prepare a new generation of highly selective and environmentally friendly MBene-based heterojunction-like nanozymes (MBAzy), they thereby enabled a highly sensitive in situ detection in the detection range of 512 pM – 125 mM (LOD = 4.44 pM). Innovative combination of bionic snake-shaped flexible electrodes and self-cleaning antibacterial electrodes for long-term monitoring of the human body's condition. Unlike previous studies, this study reveals the circadian rhythm of dopamine in human urine and its changes under different stress states, clarifies the significant difference between long-term and short-term stress on neurotransmitter levels, and explores the weak correlation between stress and fatigue, which provides new perspectives for the study of psychophysiology and related diseases.

MBene, an emerging two-dimensional material generated from bulk ternary metallic boride (MAB phase), has gradually attracted increasing research attention. However, the fabrication of MBene is still a great challenge, resulting in no literature reported about the application of MBene in energy storage fields (e.g. lithium-ion batteries). It is not advisable to adopt the same HF etching strategy which is generally used for the fabrication of MXene owing to the severely corrosive and toxic properties of the HF acid. Here, a fluorine-free hydrothermal-assisted alkane solution etching method is used to prepare the two-dimensional (2D) MoB MBene from MoAlB. The 2D MoB MBene as an anode material in LIBs exhibits a high electrochemical performance, the results exhibit a reversible specific capacity of 144.2 mAh g −1 after 1000 cycles at the current density of 2 A g −1 , which is higher than many reported MXene anodes. This fluorine-free method provides a promising green strategy for exploring series of MBene materials for a wealth of application fields.

Addressing the global freshwater crisis demands advanced solutions where solar-driven interfacial evaporation (SDIE) shows promise, yet integrated photothermal-photocatalytic synergy within a single platform remains fundamentally challenging. An accordion-like Mo 2 AlB 2 MBene is pioneered and engineered into a crosslinked MBene/Polyvinylachohol (PVA)/meso-tetra (4-carboxyphenyl) porphyrin (TCPP) composite membrane (MPTM) that synergistically unifies solar harvesting and catalytic degradation. This architecture leverages accordion-like MBene nanosheets and interfacial porphyrin coordination to establish a dynamic hydrophilic network with exceptional broadband absorption (93.3% average, 200–2500 nm). Through Schottky junction formation and charge redistribution, the system achieves unprecedented solar evaporation rates (2.24 kg m − 2 h −1 under 1 sun) while concurrently generating reactive oxygen species (•OH/•O 2 − ) that degrade 98.7% organic pollutants (10 ppm rhodamine B) in 2 h. The MPTM sustains > 85% evaporation efficiency during long-term stability operation (Bohai seawater, 200 h) with < 4% efficiency decay, establishing a new paradigm for solar-powered water purification.

Improving the room temperature ionic conductivity of solid-state polymer electrolytes for lithium batteries is a big challenge. Exploring new composite polymer electrolytes is one of the important solutions. Herein, a new inorganic two-dimensional layered metal boride nanomaterial (MBene) was first applied to the polymer electrolyte. The hyperbranched cross-linking composite polymer electrolyte is prepared by free radical polymerization of double bond modified MBene and hyperbranched ether with double bonds in the presence of PVDF-HFP and lithium salt. c provided by the two-dimensional layered material and the characteristics of adsorbing lithium salt anion. As a result, the room temperature ionic conductivity of DBMBene-DBHPG-PH CPEs reaches 9.35 × 10–4 S cm–1. Combination of ATR-FTIR spectra, XANES spectra, and DFT calculation reveals the influence of MBene on ion transport. Dendrite-free growth with high reversibility can be maintained for more than 2000 h by lithium plating/stripping in lithium symmetric batteries. The solid electrolyte can be adapted to LFP and LMFP, NCM523 high-voltage cathode materials. It is worth mentioning that the assembled pouch cell also can run stably for 150 cycles at 0.1 C, showing higher cycle capacity. This work not only demonstrates a novel MBene-based composite polymer electrolyte and provides an effective strategy to prevent the aggregation of inorganic fillers in polymer electrolyte but also exhibits excellent application prospects of two-dimensional layered MBene material in solid polymer electrolyte for high-energy density solid-state lithium batteries.
