Ice formation on equipment and infrastructure surfaces can lead to severe damage and operational disruptions, necessitating advancements in passive anti-icing technologies to enhance de-icing efficiency. Superhydrophobic materials offer notable improvements, such as minimal water affinity and reduced ice adhesion. However, their practical application is hindered by limited durability and vulnerability to cold and humid conditions. This study presents the development of a micro-nanostructured ZrN/MoSe 2 photo-electrothermal superhydrophobic composite coating, which exhibits physical and chemical self-cleaning capabilities both day and night. This innovative coating rapidly heats due to the combined effects of solar absorption and Joule heating. It reaches 89.4 °C in 600 s under simulated sunlight and 81 °C with a 15 V electrical input in 300 s. With a contact angle exceeding 155°, it demonstrates superior self-cleaning abilities. Moreover, the coating retains its exceptional anti-icing and de-icing properties even after exposure to mechanical stress, abrasion, and harsh chemical environments. It can rapidly melt ice from surfaces in just 66 s at −20 °C under one sun, achieving a 76 % efficiency in photo-thermal de-icing. Electro-thermal de-icing tests reveal that the coating can melt ice in 55 s with an 87 % efficiency. These promising features, attributed to the unique properties of ZrN nanoparticles and MoSe 2 nanosheets, significantly provide substantial advancements in superhydrophobic coating technologies. They offer the potential for large-scale production and enhanced performance in ice management.

Nitro-aromatic explosives existing on the surface of the Earth are difficult to degrade, and they greatly harm the ecological environment and human security. Herein, we successfully conducted the large-scale synthesis of novel flower-like MoSe2 3D microspheres and nanospheres by a simple hydrothermal method. The two types of MoSe2 3D spheres had a high crystal quality with abundant nanosheets, and their diameters were approximately 1.5 μm and 300–400 nm, respectively. The Brunauer–Emmett–Teller (BET) and UV-vis diffuse reflectance spectra (UV-vis DRS) analyses revealed that the specific surface area and the band gap of MoSe2 microspheres and nanospheres were 33.3 m2 g−1 and 1.68 eV and those of the nanostructures were 13.6 m2 g−1 and 1.52 eV, respectively. Moreover, two different morphologies of MoSe2 were used for the degradation of nitrobenzene (NB), p-nitrophenol (PNP) and 2,4-dinitrophenol (2,4-DNP) through a photocatalytic process. The results demonstrated that the three nitro-aromatic explosive solutions NB, PNP and 2,4-DNP (40 mg L−1) could be completely degraded by MoSe2 3D microspheres under visible-light irradiation in 3.5 h, 1.5 h and 2.5 h, and the degradation time for MoSe2 nanospheres was 4.5 h, 2.5 h and 4 h, respectively. The mechanism of the photocatalytic reaction was also investigated in detail, and the photocatalytic degradation process was found to follow the pseudo-first-order kinetics. Our study demonstrated the potential application of MoSe2 microspheres as a photocatalyst for the degradation of nitro-aromatic explosives and other organic contaminants.

This study proposes a novel and efficient Ag quantum dots (QDs)/MoSe 2 @two-dimensional transition metal carbide/nitride (MXene)/copper foam (CF) composite electrode to address the challenge of electrocatalytic degradation of antibiotics in water. The electrode formed a unique electron donor–acceptor system by loading Ag QDs and heterostructured nanosheets on CF, significantly facilitating charge transfer and segregation at the interface. The catalytically active sites at the edges and defective locations of MoSe 2 in conjunction with the two-dimensional MXene structure, which formed an efficient electron transfer channel, promoted the electron transfer from the interior to the surface and accelerated the hydrogen adsorption and reduction reactions. Moreover, the charge redistribution at the interface of Ag QDs and MoSe 2 @MXene formed interfacial dipoles, increasing the active sites on the catalyst surface and promoting the generation of cathodic atomic hydrogen (H*). Under optimal conditions, the degradation rate of tigecycline (TGC) reached as high as 90.1 % ± 2.4 % within 60 min. The anode-generated OH and HClO, along with the cathode-generated H, further promoted the degradation of TGC through co-catalysis. The degradation pathways were analyzed using density-functional theory (DFT) calculations and liquid chromatography-mass spectrometry (LC-MS) techniques. Moreover, toxicity analysis of the degradation products was carried out to ensure the safety of the treated wastewater discharge. A reflux continuous effluent reactor was also designed to achieve high degradation efficiency and low energy consumption after stable operation, laying the foundation for industrial applications. This technology provides new ideas for the design of green, efficient, stable, and low-consumption electrocatalytic reactors and contributes to a sustainable future environment.

Sn-based perovskite materials with nontoxic, low cost, and unique structure have attracted much attention. However, their efficiency only reaches 14.09% due to the higher carrier recombination rate and short carrier lifetime in photovoltaic applications. Herein, the interfacial electronic structure, optical absorption, interfacial charge transfer mechanism, and photovoltaic performance of the CsSnBr 3 /MoSe 2 perovskite heterostructure are systematically investigated by theoretical calculation and experimental observation. The results indicate that the strong coupling and hybridization of interfacial electronic states can lead to a narrowing bandgap, which induces an excellent optical absorption of the CsSnBr 3 /MoSe 2 perovskite heterostructure in the visible spectrum. Excitingly, the charge transfer at the interface forms a built-in electric field, which can effectively promote the interfacial charge transfer between CsSnBr 3 (001) and MoSe 2 monolayer, complying with a Z-scheme mechanism. Moreover, the photovoltaic performance of the CsSnBr 3 /MoSe 2 heterostructure significantly enhances due to excellent light absorption and Z-scheme system for extending carrier lifetime. An effective strategy for designing highly efficient Sn-based perovskite solar cells is reported.

Metallic MoSe 2 with distinct platinum-like electronic configuration and compelling band gap structure exhibits zero approaching Gibbs free energy for H atom, hence can be approved as an ideal cocatalysts for H 2 evolution. However, the reports on MoSe 2 cocatalyst still leaves much room. Here, two dimensional ultrathin MoSe 2 nanosheets bedecked Zn 0.5 Cd 0.5 S nanoparticles were reported as efficient photocatalyst, in which metallic MoSe 2 nanosheets cocatalyst will do duty for electron sink to promote the separation of charge carriers and prolong the electrons lifetime, thus benefiting the improved photocatalytic H 2 evolution activity. As a result, Zn 0.5 Cd 0.5 S/MoSe 2 composite with an optimized 9 wt% MoSe 2 presents a higher H 2 evolution activity of 4853.3 μmol g -1 h −1 , 3.57 folds of pure Zn 0.5 Cd 0.5 S sample (1361.0 μmol g -1 h −1 ). Meanwhile, the greatly enhanced photo-reduction efficiency for toxic heavy metal Cr (VI) ion by Zn 0.5 Cd 0.5 S/MoSe 2 composite further certifies the promoted separation of electron- hole pairs. These results turned out that MoSe 2 is qualitied as candidate to serve as promising co-catalyst for photocatalyst energy conversion and decontamination.

Nano heterostructures relying on their versatile construction and the breadth of combined functionality have shown great potential in energy storage fields. Herein, 2D sandwiched MoSe 2 /TiO 2− x /graphene nano heterostructures are designed by integrating structural and functional effects of each component, aiming to address the rate capability and cyclic stability of MoSe 2 for sodium ion capacitors (SICs). These 2D nano heterostructures based on graphene platform can facilitate the interfacial electron transport, giving rise to fast reaction kinetics. Meanwhile, the 2D open structure induces a large extent of surface capacitive contribution, eventually leading to a high rate capability (415.2 mAh g −1 @ 5 A g −1 ). An ultrathin oxygen deficient TiO 2− x layer sandwiched in these nano heterostructures provides a strong chemical-anchoring regarding the products generated during the sodiation/desodiation process, securing the entire cyclic stability. The associated sodiation/desodiation mechanism is revealed by operando and ex situ characterizations, which exhibits a strong solid electrolyte interphase (SEI) dependence. The simulations verify the dependent sodiation products and enhanced heterostructural chemical-anchoring. Assembled SICs based on these nano heterostructures anode exhibit high initial Coulombic efficiency, energy/power densities, and long cycle life, shedding new light on the design of nano heterostructure electrodes for high performance energy storage application.

High-performance sodium-ion batteries (SIBs) are highly expected in the field of large-scale static energy storage due to the low expenditure and abundant sodium resource. However, the sodium storage performance of anode materials for SIBs has suffered from the foot-dragging reaction kinetics arising from large-size Na + during intercalation/deintercalation, which imposes more stringent requirements on the morphology and structure of the potential anode electrodes. Herein, we successfully designed and synthesized a three-dimensional (3D) heterojunction as anode material for SIBs, which assembled by interlayer-expanded MoSe 2 nanosheets perpendicularly anchored on the nitrogen-doped branched TiO 2 @C nanofibers (MoSe 2 @NBT@CNFs). Not only does the branched TiO 2 @C nanofibers suppress the severe self-aggregation of MoSe 2 nanosheets but also buffer the volume expansion during the cycling process. Moreover, an expanded interlamellar distance of MoSe 2 nanosheets accelerate sodium ion diffusion, and strong chemical interactions between MoSe 2 nanosheets and carbon nanofibers are conducive to improve the charge-transfer kinetics and reinforce the structural durability. As might be expected, the MoSe 2 @NBT@CNFs anode can deliver excellent cycling performance with high reversibility (315.2 mAh g 1 after 800 cycles at 2 A g 1 ) and remarkable rate capability (194.2 mAh g 1 at 30 A g 1 ). The rational design strategy could offer guidance for developing high-performance metal chalcogenide-based electrode materials for SIBs.

Herein, a novel asymmetric supercapacitor (ASC) with high energy density is fabricated based on the NiSe@MoSe2 nanosheet arrays and the nitrogen-doped pomelo mesocarps-based carbon nanosheet (N-PMCN) as a positive electrode and a negative electrode, respectively. The novel NiSe@MoSe2 nanosheet arrays are designed and prepared by a facile one-step hydrothermal growth method from nickel foam as a nickel precursor and nucleation framework. The N-PMCN is prepared using simultaneous CaCl2 activation and urea nitrogen-doped processes from thepomelo mesocarps as a biomass-based carbon precursor. Because of the unique nanosheet array architecture of NiSe@MoSe2 and interconnected sheet-like porous morphology with high nitrogen content (∼9 wt %) of N-PMCN, they exhibit a maximum specific capacity of 128.2 mAh g–1 and high specific capacitance of 223 F g–1 at a current density of 1 A g–1. Moreover, the assembled novel NiSe@MoSe2//N-PMCN ASC device with a maximum operating voltage of 1.65 V has demonstrated a high energy density of 32.6 Wh kg–1 at a power density of 415 W kg–1 and outstanding cycling stability with 91.4% capacitance retention after 5000 cycles in aqueous electrolyte.

Transition metal dichalcogenides (TMDCs) are considered to have remarkable electromagnetic (EM) wave attenuation due to their perfect dielectric property and graphene-like structure, but they still often fail to function due to impedance mismatch problems. Here, using a multilayer coating strategy, we prepared flower-like Fe 3 O 4 @SiO 2 @MoSe 2 absorbers with core–shell structure. SiO 2 can form the Fe 3 O 4 -SiO 2 and SiO 2 -MoSe 2 heterogeneous interfaces when it is applied to the Fe 3 O 4 surface as an impedance matching layer in the Fe 3 O 4 @SiO 2 @MoSe 2 composite, increasing the interfacial polarization loss to the absorber. In addition, Fe 3 O 4 @SiO 2 as a magnetic core also reduces the relative density of the substance compared to Fe 3 O 4 . Products with the absorption performance of various electromagnetic waves were produced by varying the amount of magnetic components (Fe 3 O 4 @SiO 2 ) in the absorber. With a minimal reflect loss (RL) of − 51.86 dB and an effective absorption bandwidth (EAB, RL < -10 dB) of 4.96 GHz at a matching thickness of 1.8 mm, the Fe 3 O 4 @SiO 2 @MoSe 2 (sample S3) demonstrated exceptional properties in EM wave absorption. In addition, we synthesized Fe 3 O 4 @MoSe 2 and determined its RL value and maximum EAB (EAB max ) in order to highlight the significance of the impedance matching layer SiO 2 . Fe 3 O 4 @MoSe 2 appears to perform less well than Fe 3 O4@SiO 2 @MoSe 2 in terms of EM wave absorption, with a minimal RL value of -50.20 dB and an EAB max of only 2.00 GHz at the matching thickness of 4.8 mm. The remarkable properties in EM wave absorption of Fe 3 O 4 @SiO 2 @MoSe 2 is the result of the combined effect from impedance match and loss mechanisms of various compositions, so the component SiO 2 has a non-negligible function as an impedance matching layer. This study has blazed the trail for developing the lightweight and excellent performance of absorbers.

The improvement of surface reactivity in noble-metal-free cocatalysts is crucial for the development of efficient and cost-effective photocatalytic systems. However, the influence of crystallinity on catalytic efficacy has received limited attention. Herein, we report the utilization of structurally disordered MoSe 2 with abundant 1T phase as a versatile cocatalyst for photocatalytic hydrogen evolution. Using MoSe 2 /carbon nitride (CN) hybrids as a case study, it is demonstrated that amorphous MoSe 2 significantly enhances the hydrogen evolution rate of CN, achieving up to 11.37 μmol h −1 , surpassing both low crystallinity (8.24 μmol h −1 ) and high crystallinity MoSe 2 (3.86 μmol h −1 ). Experimental analysis indicates that the disordered structure of amorphous MoSe 2 , characterized by coordination-unsaturated surface sites and a rich 1T phase with abundant active sites at the basal plane, predominantly facilitates the conversion of surface-bound protons to hydrogen. Conversely, the heightened charge transfer capacity of the highly crystalline counterpart plays a minor role in enhancing practical catalytic performance. This approach is applicable for enhancing the photocatalytic hydrogen evolution performance of various semiconducting photocatalysts, including CdS, TiO 2 , and ZnIn 2 S 4 , thereby offering novel insights into the advancement of high-performance non-precious catalysts through phase engineering.

Developing composite materials with a rational composition structure has been a critical strategy to obtain superior electromagnetic (EM) wave absorption materials. CoNi/MoSe 2 composites were synthesized by a two-step method in this work. Firstly, the flower-like MoSe 2 was synthesized by hydrothermal method , and then the CoNi alloy was loaded on the MoSe 2 surface by an electroless plating method. It is worth noting that in this paper, PdCl 2 was not used for activation during the electroless plating process, and the flower-like structure of MoSe 2 was not destroyed. In order to investigate the effect of different Co/Ni molar ratios on the absorption performance of the CoNi/MoSe 2 composites, three samples with Co to Ni molar ratios of 1:3, 1:1, 3:1 and two other samples with only one metal (Ni or Co) were prepared. The analysis results show that the minimum reflection loss(RL) value of Ni/MoSe 2 is −18.01 dB and the maximum effective absorption bandwidth(EAB) of Co/MoSe 2 is 2.16 GHz. In comparison, the CoNi/MoSe 2 composite exhibits the best EM wave absorption performance when the Co/Ni ratio is 1:3, and the minimum RL can reach −48.6 dB at a matching thickness of only 1.8 mm. And when the matching thickness is 1.4 mm, the broadest EAB is 3.76 GHz. Therefore, this work provides a new research idea for the design of broadband and efficient EM wave absorbers.
