Two high-performance PEs are constructed by encapsulating liquid electrolytes within crosslinked polymer networks. • The as-prepared PEs exhibit high ionic conductivity and highly reversible Mg plating/stripping behavior. • The solvation structure of liquid electrolytes under confinement within crosslinked polymer networks is elucidated. • The intrinsic origin of the influence of liquid electrolytes on the electrochemical performance of PEs is revealed. Developing polymer electrolytes (PEs) with high ionic conductivity and compatibility with Mg metal anodes remains a key challenge for solid-state rechargeable magnesium batteries (RMBs). Herein, two PEs, G3-PE1 and G4-PE1, were prepared by immobilizing highly active MgCl 2 -AlCl 3 -triethylene glycol dimethyl ether (MgCl 2 -AlCl 3 -G3) and MgCl 2 -AlCl 3 -tetraethylene glycol dimethyl ether (MgCl 2 -AlCl 3 -G4) liquid electrolytes within crosslinked polymer networks, respectively. Benefiting from the retention of the solvation structure of the liquid electrolytes and the structural support provided by the crosslinked polymer networks, both G3-PE1 and G4-PE1 exhibited high ionic conductivity and stable electrochemical performance. At 30 °C, the ionic conductivities of G3-PE1 and G4-PE1 reached 2.14 × 10 −3 and 1.07 × 10 −3 S cm −1 , respectively, with corresponding Mg 2+ transference numbers of 0.5801 and 0.4267. Moreover, Mg//Mg symmetric cells employing these PEs maintained stable cycling for over 1500 h at a current density of 25 μA cm −2 . Compared with G4-PE1, G3-PE1 exhibited weaker Mg 2+ -ether coordination, resulting in superior electrochemical performance. The Mo 6 S 8 //G3-PE1//Mg full cell delivers a discharge capacity of 54.6 mAh g −1 after more than 350 cycles at 0.1C, demonstrating excellent cycling stability. Immobilizing highly active liquid electrolytes within crosslinked polymer networks therefore provides an effective route for developing high-performance PEs for RMBs.

en This link goes to a English section zh This link goes to a Chinese section Lithium–sulfur batteries have attracted extensive interest owing to their exceptionally high theoretical energy density and environmental benignity. However, their practical performance remains severely constrained by intrinsic challenges, including the polysulfide shuttle effect and large volume expansion during cycling, which markedly compromise energy efficiency and fall far short of the requirements for commercialization. To address these challenges, we modify a commercial separator (PP) with a dual-transition-metal Mo 2 Nb 2 C 3 MXene, whose surface terminations are precisely regulated via distinct etching strategies, thereby substantially enhancing the electrochemical performance of lithium–sulfur batteries. Compared with cells employing the pristine commercial separator, all PP@Mo 2 Nb 2 C 3 -based cells deliver superior rate performance at a high current density of 3C. Notably, the PP@Mo 2 Nb 2 C 3 -Cl cell retains a high discharge capacity of 589 mAh g −1 after 200 cycles, nearly doubling that of the cell with the commercial PP separator (307 mAh g −1 ). At all tested C-rates, the PP@Mo 2 Nb 2 C 3 -based cells delivered higher discharge capacities than those employing the commercial PP separator. Overall, modification of Celgard 2500 with the dual-transition-metal Mo 2 Nb 2 C 3 MXene effectively suppresses the polysulfide shuttle, enhances sulfur utilization, and substantially prolongs the cycle life of lithium–sulfur batteries. This work provides valuable insights into the rational design and application of MXenes as functional modifiers for advanced lithium–sulfur batteries. 摘要 en This link goes to a English section zh This link goes to a Chinese section 锂硫电池因其高理论能量密度和对环境友好受到广泛关注,但其在工作中产生多硫化物引起的穿梭效应、体积膨胀等问题严重影响电池的效率,远不足以达到商业化的要求。针对这些问题,本文研究了双过渡金属Mo 2 Nb 2 C 3 MXene对商用Celgard 2500进行改性,通过不同的刻蚀方法调控Mo 2 Nb 2 C 3 MXene端基,进而有效提升了锂硫电池的性能。与商用Celgard 2500隔膜相比,所有基于PP@Mo 2 Nb 2 C 3 的电池在3C倍率下均表现出更优异的倍率性能。值得注意的是,PP@Mo 2 Nb 2 C 3 -Cl电池在200次循环后仍保持589 mAh g −1 的高放电比容量,几乎是使用商用Celgard 2500隔膜电池(307 mAh g −1 )的两倍。在不同倍率下,PP@Mo 2 Nb 2 C 3 电池均表现出比使用商用Celgard 2500隔膜电池更高的放电比容量。总体而言,采用双过渡金属Mo 2 Nb 2 C 3 MXene对Celgard 2500隔膜进行改性,能够有效抑制多硫化物穿梭,提高硫利用率,并延长锂硫电池的循环寿命。这项工作为合理设计和应用MXene作为先进锂硫电池的功能改性材料提供了有价值的见解。

MoO 3 has been recognized as a potential photocatalyst for photocatalytic ammonia synthesis from N 2 in sacrificial reagent assisted half-reaction system, but is lacking in both sluggish kinetics of N 2 reduction due to the absence of efficient active sites and low practicality originated from high cost sacrificial reagent. Herein, aiming to simultaneously bolster N 2 reduction reaction kinetics and improve practicality, oxygen vacancy-enriched MoO 3-x nanoplates was prepared as photocatalyst for green photocatalytic ammonia synthesis by using abundant cellulose in nature as the sacrificial reagent. Under light irradiation, MoO 3-x photocatalysts simultaneously achieve ammonia production and the conversion of cellulose into high-value chemicals, and the highest NH 3 generation achieves 21.4 μmol g -1 ·h -1 under 300 W Xe lamp irradiation in cellulose solution. The excellent photocatalytic activity of MoO 3-x can be ascribed to the positive role of oxygen vacancy, which provides abundant active sites for ammonia synthesis. Meanwhile, the oxygen vacancy induces the generation of Mo 5+ in MoO 3-x , which inhibits the reduction of MoO 3-x to water-soluble H x MoO 3 , resulting in the high structure stability of MoO 3-x . This work provides new insight for the development of defect-engineered photocatalysts for green ammonia synthesis coupled with sustainable cellulose valorization.

Electrochemical uranium extraction represents a powerful means to achieve the recovery of uranium resources from nuclear wastewater, but the formation of a complex between fluoride and uranyl in common wastewater severely decreases the extraction efficiency. Herein, the isolated uranyl was predoped in O-vacancy-containing molybdenum oxide (U-MoO3–x, x < 3) to efficiently electrochemical extract uranium from fluoride-containing nuclear wastewater. In this system, the doped isolated uranyl and the vacancy of the O can strongly bind with the fluorine and uranyl in uranyl fluoride (UO2Fx), respectively, enabling the synergistic trapping of dominant species in fluoride-containing nuclear wastewater. With the coexistence of high concentration of fluoride (3 g/L), the U-MoO3–x nanosheets exhibited a removal efficiency of 95.3% for uranium, which was much higher than that of MoO3–x. Furthermore, the U-MoO3–x nanosheets displayed robust uranium extraction performance with a negligible influence of pH variations, interfering ions, and U/F ratios. This work provides a new strategy of preintroduction of uranyl species for promoted electrochemical uranium extraction in a complex environment.

Efficient oil-water separation remains a major challenge in oily wastewater treatment, highlighting the need for advanced materials that combine superwettability, structural durability, and long-term recyclability. Here, we develop a hierarchical ZOMO-PAA@CuC2O4NR@CM membrane via sequential chemical oxidation, oxalic acid etching, and spray-coating of ε-Keggin-type Na-ZnM ZOMO nanoparticles within a polyacrylic acid (PAA) matrix. The resulting architecture couples CuC2O4nanorods with hydrophilic ZOMO-PAA coatings to achieve superhydrophilicity and underwater superoleophobicity. Structural characterization confirmed uniform nanoparticle dispersion, high crystallinity, and robust framework integrity. The membrane exhibits ultrafast water spreading (0°), underwater oil contact angles above 150°, and sliding angles as low as 4°, enabling broad-spectrum oil repellence, antifouling, and self-cleaning. The as-prepared membrane efficiently separates both surfactant-free and surfactant-stabilized emulsions, including aliphatic and aromatic oils stabilized by cationic, anionic, and non-ionic surfactants, with high water fluxes (1695–2675 L·m−2·h−1and ~900 L·m−2·h−1, respectively) and separation efficiencies above 99.1%. The membrane further demonstrates chemical stability under acidic, alkaline, and saline conditions, alongside consistent oil–water separation behavior across multiple cycles. These findings establish ZOMO-PAA@CuC2O4NR@CM as a robust and scalable platform for advanced oily wastewater treatment.

Adopting compostable materials that return to nature akin to organisms can mitigate concerns regarding the ecological footprint associated with the widespread deployment of soft robots across various fields, including medicine, agriculture and environmental exploration. Nevertheless, current implementations are constrained by the lack of reliability of sustainable soft actuators, difficulties in achieving multifunctionality of biodegradable electronics, and uncertain eco-compatibility of by-products. Here we address these challenges by providing a framework that integrates sophisticated transient inorganic electronics with durable yet degradable elastomer (polyglycerol sebacate) and polyanhydride-based adhesive in compostable soft embodiments. Our soft electronic fingers withstand over 1,000,000 actuation cycles and feature 21 high-density electronic components that enable proprio-/exteroceptive sensing and environmental intervention. The high survival rates of oats germinated in soils containing feedstock composted from not only polymers but also electronic materials, such as Si, Mo and Mg, indicate that our robot is seamlessly integrated into the ecosystem. All these advances bridge the gap between sustainability and performance in soft robots.

Molybdenum is an expensive rare metal with many application, however discharged effluents containing Mo(VI) ions from various industries constitute potential hazards to human health and the ecosystem. Thus, it is demanded to develop appropriate methods to separate and recover molybdenum from industrial wastewater. In the present work, polyethyleneimine (PEI) functionalized magnetic silicon (PEI@SiO 2 @Fe 3 O 4 ) nanocomposite was synthesized by a facile approach (60 °C, 1 h), and then for the first time used as the sorbent for efficient removal and recovery of Mo(VI) ions. The prepared PEI@SiO 2 @Fe 3 O 4 nanocomposite was then characterized using Fourier transform-infrared spectrometer, scanning electron microscoper, etc. Investigations of adsorption performances of the PEI@SiO 2 @Fe 3 O 4 demonstrated its high adsorption capacity of 409.8 mg/g at 298 K and fast adsorption kinetics with an equilibrium time of 45 min, while the sorption process was spontaneous, endothermic and well fitted by Langmuir isotherm and the pseudo-second order kinetic model. The possible adsorption mechanisms include coordinate bonds and electrostatic interaction. The sorbed Mo(VI) ions were completely eluated off from PEI@SiO 2 @Fe 3 O 4 sorbent using a Na 3 PO 4 solution (20 g/L) within only 2 min. Outstanding reusability of PEI@SiO 2 @Fe 3 O 4 was illustrated after seven adsorption–desorption cycles with only 7 % loss in sorption capacity. The PEI@SiO 2 @Fe 3 O 4 was then applied to the treatment of real wastewaters containing Mo(VI), and very satisfactory results were achieved. These results suggest that the PEI@SiO 2 @Fe 3 O 4 nanocomposite is a potential sorbent for removing and recovery of Mo(VI) from wastewater.

The development of efficient photocatalytic systems for hydrogen peroxide (H 2 O 2 ) production from pure water remains a huge challenge due to rapid charge recombination and insufficient redox capability in single-component photocatalysts. Herein, we successfully constructed the S-scheme oxygen-vacancy-enriched MoO 3 quantum dots (Ov-MoQDs)/sulfur-vacancy-rich Zn 3 In 2 S 6 (Sv-ZIS) heterostructures by coupling Sv-ZIS nanosheets with Ov-MoQDs. The optimized 3Ov-MoQDs/Sv-ZIS sample achieves an outstanding H 2 O 2 production rate of 85.8 ± 3.1 μM under visible light illumination for 1 h in the pure water, which is about 3.5 and 45.1 times higher than those of Sv-ZIS and Ov-MoQDs, respectively. Through comprehensive in situ and ex situ characterizations combined with theoretical calculations, we demonstrate that the enhanced activity stems from efficient charge separation and transfer across the heterogeneous interfaces via an S-scheme mechanism. Furthermore, the H 2 O 2 photosynthesis over Ov-MoQDs/Sv-ZIS heterostructures is found to proceed through a two-step single-electron oxygen reduction reaction (ORR) pathway. This work provides valuable insights into the rational design of advanced heterostructured photocatalysts for sustainable chemical synthesis.

Driven by the rapid advancement of electronic devices and wireless communication technologies, there is an urgent demand for high-performance microwave absorbing materials. In this work, one-dimensional MoO 2 /C composites were synthesized through an in-situ polymerization-pyrolysis strategy. By precisely tuning the pyrolysis temperature, remarkable microwave absorption performance was achieved. The resulting material exhibits a minimum reflection loss of −59.1 dB at a matching thickness of 1.7 mm and delivers an effective absorption bandwidth of 5.6 GHz at 2.0 mm. Furthermore, it demonstrates a radar cross-section of 27.08 dB·m² at a 0° scattering angle. Comprehensive experimental and theoretical analyses reveal that the enhanced electromagnetic wave attenuation is primarily attributed to one-dimensional interfacial polarization at the interfaces between MoO 2 nanorods and porous carbon layers, as well as efficient axial electron transport pathways. This work presented a viable strategy for the preparation of one-dimensional MoO 2 -based dielectric microwave absorption materials.

Electrocoagulation is progressively becoming an ecologically friendly water treatment method owing to its lack of secondary pollution, high active ingredient concentration, high treatment effectiveness, simple equipment, and simplicity of automated control implementation. Herein, electrocoagulation is offered as a method for treating wastewater containing azo dyes using a revolutionary flexible electronic fabric that can be mass-producible at a reasonable price. A computer-controlled machine embroiders 316L stainless steel fiber (316L SSF) onto an insulating fabric to manufacture a flexible electronic device of cathode and anode with a monopolar arrangement on the fabric surface. Using methyl orange (MO) solution to simulate azo dye wastewater, the decolorization rate of 500 ml MO reached 99.25% under the conditions of 50 mg·L −1 initial mass concentration, 120 min electrolysis time, 15 mA·g −1 current density, 1 cm electrode spacing, 0.1 mol·L −1 NaCl, pH 7.6, 200 r·min −1 rotational speed of the stirrer, and 22−25 °C room temperature. In addition, it is feasible to embroider flexible electronic fabrics with varied sizes and numbers of electrodes based on the amount of treated sewage to increase the degradation rate, which has significant practical application value.

The construction of the materials with one-dimensional (1D) hollow structure using Metal-organic frameworks (MOFs) as the templates has attracted much attention for applied in various fields. Herein, MOF-derived 1D Ru/Mo co-doped Co 3 O 4 hollow microtubes have been obtained via a simple solvothermal method . The as-synthesized samples are characterized by using XRD, FESEM , TEM , XPS, PL and BET. The sensing measurement reveals that when doping amount of Mo and Ru is 1% and 0.3%, the Co 3 O 4 sample exhibits the best sensing performance. Specially, 0.3% Ru/Mo-Co 3 O 4 sample exhibits high responses of 126–100 ppm TEA at a low operating temperature of 160 °C, which are about 18.5 times than that of pure Co 3 O 4 . Furthermore, it shows rapid response/ recovery speed (5 s/7 s), good selectivity and repeatability as well as excellent long-term stability. The good TEA sensing performance is attributed to the construction of 1D hollow architecture and synergistic effect of Ru/Mo co-doping. Thus, it is expected to be a promising sensing material for high-performance detection of TEA gas. In addition, this work provides an useful inspiration for preparation of MOF-derived materials with 1D hollow architecture for achieving excellent performance in various fields.

Fluorinated-defective titanium dioxide (F-TiO2−x) was successfully synthesized by fluorination of TiO2 through the hydrothermal method. The microstructure and physicochemical properties of the catalyst were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and UV–vis diffuse reflectance spectroscopy (UV–vis DRS). As expected, F-TiO2−x demonstrates high photocatalytic activity and stability on dye degradation. Results indicated that fluorine element can effective for stabilizing Ti3+ and oxygen vacancies on the surface of F-TiO2−x. With the increase in the amount of hydrofluoric acid (HF) added, the photocatalytic performance of the prepared material is first increased and then decreased, and the catalyst shows the best performance when the amount of HF added is 0.3 mL. For three different dyes, the catalysts all showed a certain photocatalytic degradation performance, and the degradation effect of rhodamine B was the best.
