In this work, a facile strategy for embedding graphene (GR) nanosheets into carbon-coated MoSe 2 (MoSe 2 @C@GR) hybrid nanofibers has been developed by a simple electrospinning route. One dimensional nanofibers have excellent structural stability resulting from strong tolerance to stress change. The highly conductive graphene nanosheets play an excellent coating effect on MoSe 2 to inhibit the growth of MoSe 2 nanosheets on the nanofiber surface and enhance the conductivity of hybrid nanofibers, which substantially improves the rate performance and cycle stability of carbon-coated MoSe 2 (MoSe 2 @C) nanofibers. In particular, the MoSe 2 @C@GR electrode delivers a high discharge capacity of 366.9 mAh g −1 after 200 cycles at 0.2 A g −1 , meanwhile exhibits superior rate performance. The analysis of Nyquist plots reveals that the addition of graphene nanosheets can greatly strengthen the kinetics of electrode reaction and the electrochemical activity.

Transition metal dichalcogenides (TMDCs) are considered as the potential electrocatalysts for hydrogen evolution reaction (HER) owing to the two-dimensional (2D) geometry and tunable band gap. However, both the inefficient electron transferring and high Gibbs free energies for hydrogen adsorption (ΔG H *) in MoSe 2 limit its further improvement in catalytic performance. Herein, the few-layered 1T@2H–MoSe 2 composite nanosheets are synthesized by one-pot hydrothermal reaction . It is found that the morphology and composites of nanosheets could be influenced by hydrothermal reaction parameters. As compared to pure 2H–MoSe 2 , 1T@2H–MoSe 2 electrode exhibits remarkable activity for HER with a low overpotential (118 mV), small Tafel slope (65.8 mV·dec −1 ) as well as large electrochemical active area (C dl = 37.5 mF cm −2 ) in acid electrolytes. Density functional theory (DFT) calculations demonstrate that ΔG H * of 1T@2H–MoSe 2 (0.232 eV) is much lower than these of pure 1T-MoSe 2 and 2H–MoSe 2 . It could be ascribed to both the optimized charge transfer and increased density of active sites in 1T@2H–MoSe 2 nanosheets.

The acquisition of real-time temperature monitoring during photothermal therapy is significant to prevent unnecessary damage to healthy tissues. However, owing to complexity and diverse factors in microenvironment of cells, there still remain considerable challenges in achieving noninvasive temperature measurement and manipulation in therapeutic process. Herein, biocompatible Nd-doped MoSe 2 nanosheets have been developed on the premise of excellent photothermal effect, which manifest desirable photoluminescence and distinct temperature self-monitored capability in near-infrared I and II bio-windows. Based on thermally coupled energy levels of Nd ions, the real-time monitoring on temperature changes in intracellular environment can be realized which provide instant temperature feedbacks to avoid side effects from hyperthermia. Exclusive of detrimental elements such as F and Pb, the objective nanosheets manifest satisfactory biosafety and can induce effective tumor ablation under near-infrared irradiation with photothermal conversion efficiency up to 40.8%, providing an innovative vision for developing more precisely and safely photothermal approaches.

Transition metal dichalcogenides (TMDs) as materials for aqueous zinc-ion batteries (ZIBs) have received a lot of interest because of their large theoretical capacity and unique layered structure. However, the sluggish kinetics and inferior cyclic stability limit the usefulness of ZIBs. In the present investigation, the interlayer spacing enlarged MoSe 2 hollow nanospheres comprised of nanosheets with ultrathin shells have been successfully synthesized through a combined strategy of template assistance and anion-exchange reaction. The hierarchical ultrathin nanosheets and hollow structure effectively suppress the agglomeration of pure nanosheets and ameliorate volume fluctuations induced by ion migration during (dis)charging/charging. The interlayer expansion provides good channels for the transport of Zn 2+ ions and speeds up the insertion/extraction of Zn 2+ . In addition, in-situ carbon modification can significantly improve electronic conductivity. Therefore, the electrode prepared from MoSe 2 hollow nanospheres with enlarged interlayer spacing not only exhibits outstanding cycle stability (capacity retention of 94.5% after 1600 cycles) but also exhibits high-rate capability (266.1 mA h g −1 at 0.1 A g −1 and 203.6 mA h g −1 at 3 A g −1 ). This work could provide new insights into the design of cathode using TMDs of hollow structure for Zn 2+ storage.

Sodium-ion batteries are a promising substitute for lithium batteries due to the abundant resources and low cost of sodium. Herein, honeycomb-shaped MoSe 2 /reduced graphene oxide (rGO) composite materials are synthesized from graphene oxide (GO) and MoSe 2 through a one-step solvothermal process. Experiments show that the 3D honeycomb structure provides excellent electrolyte penetration while alleviating the volume change during electrochemical cycling. An anode prepared with MoSe 2 /rGO composites exhibits significantly improved sodium-ion storage properties, where a large reversible capacity of 215 mAh g −1 is obtained after 2700 cycles at the current density of 30.0 A g −1 or after 5900 cycles at 8.0 A g −1 . When such an anode is paired with Na 3 V 2 (PO 4 ) 3 to form a full cell, a reversible specific capacity of 107.5 mAh g −1 can be retained after 1000 cycles at the current of 1.0 A g −1 . Transmission electron microscopy, X-ray photoelectron spectroscopy and in situ X-ray diffraction (XRD) characterization reveal the reversible storage reaction of Na ions in the MoSe 2 /rGO composites. The significantly enhanced sodium storage capacity is attributed to the unique honeycomb microstructure and the use of ether-based electrolytes. This study illustrates that combining rGO with ether-based electrolytes has tremendous potential in constructing high-performance sodium-ion batteries.

BACKGROUND Antibiotic pollution in aquatic environments poses significant threats to human health and ecosystems by promoting the spread of antibiotic resistance. RESULTS This study investigates the use of MoSe 2 -based bimetallic composite selenides (MoSe 2 /CoSe 2 and MoSe 2 /MnSe) to activate peroxymonosulfate (PMS) for the oxidation of levofloxacin (LEF), a model fluoroquinolone antibiotic. The composites were synthesized via a solvothermal method and characterized using SEM, TEM, XRD, and XPS, confirming the formation of heterojunction interfaces and the presence of active metal sites. Catalytic performance tests demonstrated that MoSe 2 /CoSe 2 and MoSe 2 /MnSe significantly enhanced LEF degradation, achieving removal efficiencies of 92.98% and 89.4%, respectively, compared to 49.07% with MoSe 2 alone. Optimization of reaction parameters revealed that PMS dosage, catalyst dosage, and pH critically influence degradation efficiency. Reusability tests confirmed the catalysts' stability over multiple cycles with minimal loss in activity. Electron paramagnetic resonance (EPR) and radical quenching experiments identified sulfate radicals (SO 4 •- ) as the primary active species driving LEF degradation. CONCLUSION This work provides a robust theoretical foundation for the application of SR-AOPs in wastewater treatment, highlighting the potential of MoSe 2 -based composites in mitigating antibiotic contamination. © 2025 Society of Chemical Industry (SCI).

Development of highly-efficient heterostructured photocatalysts capable of fully utilizing full solar spectrum has emerged as a focal point in photocatalytic H 2 evolution from water splitting. Herein, Mn 0.2 Cd 0.8 S/MoSe 2 composite was successfully constructed by attaching full-spectrum responsive MoSe 2 nanospheres on surface of Mn 0.2 Cd 0.8 S polyhedra via in-situ hydrothermal process. The optimal Mn 0.2 Cd 0.8 S/MoSe 2 -5wt% composite photocatalyst yielded the H 2 evolution rate of 34.31 mmol g –1 h –1 under full-spectrum light, significantly surpassing the activities obtained under near-infrared (NIR), ultraviolet (UV), visible (Vis), Vis-NIR and UV-Vis light alone. This outstanding property could be attributed to the synergetic effects of p−n heterojunction and photothermal effect, effectively accelerating interfacial charge transfer, elevating reaction system's temperature and expediting surface reaction, thereby promoting the photocatalytic reaction of Mn 0.2 Cd 0.8 S. This study offers a valuable perspective on utilizing MoSe 2 to construct an efficient photothermal-assisted photocatalysis system.

The exploration of high-performance, low-cost, and dual-function electrodes is crucial for anion exchange membrane water electrolysis (AEMWE) to meet the relentless demand for green H2production. In this study, a heteroatom-doped carbon-cage-supported CoSe2@MoSe2@NC catalyst with a formicarium structure has been fabricated using a scalable one-step selenization strategy. The component-refined bifunctional catalyst exhibited minimal overpotential values of 116 mV and 283 mV at 10 mA cm−2in 1 M KOH for the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), respectively. Specifically, rationally designed heterostructures and flexible carbonaceous sponges facilitate interfacial reaction equalization, modulate local electronic distributions, and establish efficient electron transport pathways, thereby enhancing catalytic activity and durability. Furthermore, the assembled AEMWE based on the CoSe2@MoSe2@NC bifunctional catalysts can achieve a current density of 106 mA cm−2at 1.9 V and maintain a favorable durability after running for 100 h (a retention of 95%). This work highlights a new insight into the development of advanced bifunctional catalysts with enhanced activity and durability for AEMWE.

We report an electrochemical non-enzymatic method for hydrogen peroxide (H2O2) detection based on Ag nanoparticle-decorated MoSe2 (Ag/MoSe2-500) hybrid nanostructures. These hybrid nanocomposites are easily prepared by in situ reduction of Ag+ on the surface of MoSe2. Benefiting from the strong synergy of Ag nanoparticles and MoSe2 nanosheets in enhancing electrical conductivity, the Ag/MoSe2-500 hybrid nanostructures perform excellent sensing activity for H2O2 electrocatalytic reduction with a wide linear range of 0.02–15.2 mM, a high sensitivity of 400.0 μA mM−1 cm−2 and a low detection limit of 0.39 μM (S/N = 3). Furthermore, the sensor displays satisfactory reproducibility and stability and is applicable for practical quantitative analysis of H2O2 in milk and orange juice samples. In a word, Ag/MoSe2-500 nanocomposites are promising candidates for non-enzymatic H2O2 sensing in the fields of biology and food science.

Single-component transition metal selenide (TMSe) hosts still struggle to balance the adsorption of lithium polysulfides (LPSs) and their catalytic conversion. Herein, a heterostructure host (MoSe 2 -CoSe@C) with an intra-spherical interwoven architecture was synthesized via impregnation-chemical vapor deposition. Benefiting from the synergy of adsorptive MoSe 2 and conductive CoSe, the heterointerface induces electron transfer from CoSe to MoSe 2 , upshifting the d-band center to enhance LPSs adsorption. Compared with their single-component hosts, the MoSe 2 -CoSe@C notably reduces the energy barriers of sulfur redox reactions, decreasing those for Li 2 S oxidation by 31.45 kJ mol −1 and for Li 2 S 4 reduction by 191.67 kJ mol −1 . Additionally, Co acts not only as a core component of the heterostructure but also induces the conversion of carbon-based materials into carbon nanotubes at high temperatures, thus forming a unique interwoven network. This network not only ensures efficient electron transport and inhibits the agglomeration of active components, but also increases the contact area between the host and active sulfur, thereby enhancing the number of effective catalytic sites. Consequently, the MoSe 2 -CoSe@C/S cathode achieves a discharge specific capacity of 582.1 mAh g −1 at a current density of 5C, with only 0.07% capacity decay per cycle over 200 cycles at 4C. This work provides a strategy to construct high-performance adsorption-catalytic hosts for lithium‑sulfur batteries (LSBs).

Establishing advanced sodium-ion batteries (SIBs) with high energy density and eco-friendly electrode materials are still far from satisfactory due to the large-size of sodium-ions and sluggish redox kinetics during electrochemical processes. Herein, a novel ultrafast kinetics net electrode assembled via MoSe 2 /MXene heterojunction is synthesized by a simple hydrothermal method followed by thermal annealing. Featuring the Van der Waals force interaction between MoSe 2 and MXene , the volumetric change during the sodium ions insertion/extraction courses is effectively restrained, and the reaction kinetics is greatly enhanced further. Meanwhile, both the high electrical and ion conductivity (lower diffusion barrier between Na + /MXene ~0.066 eV) provided by the unique MXene based net heterostructure of our hybrid materials, as evidenced by DFT calculations, are beneficial to the transportation of sodium ions, thus enabling an outstanding rate and long-cycling capability. As a result, the fabricated cells exhibit high reversible capacities of 490 mAh g −1 at 1 A g −1 , as well as 250 mAh g −1 at a high current of 10 A g −1 with a coulombic efficiency of 99.8%, indicating the excellent electrochemical performance of our hybrid materials, especially at high current. This novel net MoSe 2 /MXene heterostructure, combined with our simple synthesis strategy together, are expected to have great potential in sodium-ions storage application.

The bottleneck of alkaline hydrogen evolution reaction lies in the kinetically sluggish brought from multistep reaction processes involving water adsorption and dissociation, as well as hydrogen adsorption. In this work, we successfully synthesized o-CoSe 2 /c-CoSe 2 heterostructures anchored on MoSe 2 nanosheets to powerfully promote reaction processes. As an electrocatalyst , it exhibits a low overpotential of 112 mV at 10 mA/cm 2 and a Tafel slope of 96.9 mV/dec for an alkaline hydrogen evolution reaction . Moreover, the as-prepared catalyst can behave as both cathode and anode for overall water splitting , which only requires 1.61 V cell voltage at 10 mA/cm 2 . Significantly, the cell voltage can be further reduced to 1.53 V at 10 mA/cm 2 for water electrolysis under the simulated solar irradiation owing to such a semiconductor-based heterostructure that facilitates the separation of photogenerated charges. Here, the improving overall performance of this ternary electrocatalyst is attributed to the multifunctionality and synergistic interaction of different components in this heterogeneous material . The work provides a novel strategy to design active catalysts simultaneously using electric energy and solar energy for effective water splitting.
