Vanadium dioxide (VO₂) undergoes reversible metal–insulator transitions at critical temperature of 68 °C, rendering it promising for tunable electromagnetic applications. Here, Cr-doped VO₂/Ethyl cellulose (EC) composites are synthesized to raise the transition temperature to 87 °C while retaining shielding effectiveness values of 9.9–26.3 dB (X-band) and 10.2–25.2 dB (Ku-band). Notably, the surface temperature of material plateaus at 70 °C after exposure to one sun for 10 min, preventing passive phase transitions under light exposure. This work provides valuable insights into the design of intelligent electromagnetic interference shielding materials with active thermal regulation capabilities.

In this approach, the VO 2 nanoparticles have been successfully fabricated via combusting the low-cost precursor solution consisted of NH 4 VO 3 , C 2 H 6 O 2 and C 2 H 5 OH. By the XRD, TEM and XPS analysis, it can be found that the synthetic monoclinic VO 2 is single crystal and no impurity is defined. After dispersing the VO 2 nanoparticles into the polymer, the solar modulation of VO 2 -based composite film is up to 12.5% with luminous transmission and haze around 62.2% and 0.5%, respectively. In other words, the composite films show high performance of thermochromic properties. This could open an efficient way to fabricate low-cost and large-scale VO 2 (M) nanoparticles and thermochromic films.

VO 2 is considered as a promising anode material for lithium ion batteries , owing to its high theoretical capacity and fast ion-transfer rate. However, the development of VO 2 is hindered by the severe issues of poor electrical conductivity , large volume changes and low energy density . In this study, nano-micro structure VO 2 /CNTs spheres are well designed and successfully synthesized through a one-step solvothermal method, where the carbon nanotubes are inlayed throughout the whole microspheres . This unique structure enables carbon nanotubes to improve the ion and electron conductivity of VO 2 . Besides, it can achieve a high tap density (> 1.3 g cm 3 ) of VO 2 /CNTs electrode, which is higher than nanomaterials (< 1.0 g cm 3 ), and compatible with the current commercial anode materials. The Li + storage behavior of VO 2 /CNTs is studied systematically in the potential range 0.01–3.0 V, it can obtain a high reversible specific capacity of 537.6 mA h g −1 at the current density of 0.05 A g −1 . Furthermore, the lithium insertion/extraction reaction mechanism of nano-micro structure VO 2 /CNTs is clarified. The results demonstrate that the nano-micro structure relieves the volume changes during charge/discharge cycling. Therefore, it provides an insight to create functional materials with nano-micro structure for a wide range application.

The synergistic integration of photocatalytic nanomaterials with hydrogel matrices has emerged as a promising strategy for sustainable wastewater treatment due to their biocompatibility, stability, and cost-effectiveness. In this study, a multifunctional hydrogel was fabricated through a green synthesis route by embedding Fe₃O₄@VO₂–polydopamine (PDA) composites into a sodium alginate (SA) network via a two-step cross-linking process. Fe₃O₄ nanoparticles were synthesized by co-precipitation, followed by water bath growth of Fe₃O₄@VO₂ and in situ PDA deposition to improve interfacial stability and charge transfer. The resulting Fe₃O₄@VO₂-PDA-SA/H hydrogel exhibited excellent magnetic recoverability, high photocatalytic efficiency, and structural robustness. Malachite green (MG) and tetracycline hydrochloride (TCH), representative contaminants from aquaculture wastewater, were employed as target pollutants. The composite achieved maximum photodegradation efficiencies of 98.39 % for MG and 87.03 % for TCH, with only moderate efficiency loss after five consecutive cycles (retaining 88.38 % and 61.03 % removal, respectively). Radical quenching experiments revealed that •OH and •O₂ − played dominant roles in pollutant degradation, confirming a synergistic photocatalytic mechanism. These findings demonstrate that Fe₃O₄@VO₂-PDA-SA/H not only ensures efficient and stable photocatalysis in complex aqueous environments but also offers facile recyclability, highlighting its potential as a practical material for advanced wastewater remediation.

The rapid advancement of infrared detection technologies poses formidable challenges to conventional stealth materials. However, most existing infrared stealth materials rely on a single mechanism-either surface emissivity modulation or thermal conduction blocking-which limits their capacity to deliver durable and stable performance. Herein, a novel vanadium dioxide (VO 2 )/aramid nanofiber (ANF)/polyvinyl alcohol (PVA) aerogel composite was successfully fabricated through a vacuum filtration and freeze-drying process. In this system, ANF and PVA form a robust support framework with exceptional mechanical properties, while VO 2 nanoparticles provide dynamic thermal camouflage properties. The resulting VO 2 /ANF/PVA aerogel exhibited a low density of 0.052 ± 0.002 g/cm 3 , minimal shrinkage rate of 3.5 ± 0.2 %, high porosity of 96.5 ± 0.3 %, substantial compressive stress (0.169 ± 0.001 MPa at 75 % strain), and extremely low thermal conductivity of 0.048 ± 0.003 W/(m·K). Notably, the aerogel demonstrated significant infrared emissivity modulation (from 0.92 to 0.6) across a temperature range of 15–100 °C. As a thermal camouflage coating, it reduced the radiative temperature of a 70 °C object to 17.9 °C while maintaining stable performance for over 2000 s. This study achieved synergistic optimization of material structure and functionality through design of composite structures, offering valuable insights for developing advanced adaptive stealth materials.

Vanadium dioxide (VO 2 ) material has been deemed as a potential anode candidate for aqueous lithium-ion batteries. Among its diversified polymorphs, the latest discovered VO 2 (D) receives the fewest reports on its application in energy storage. Herein, we successfully utilized a template-free solvothermal method to prepare VO 2 (D) submicron-spherical hierarchical structures, constructed with colibacillus-like nanorods . The VO 2 (D) submicron-spheres were applied as an active anode material into the aqueous lithium-ion battery, which exhibited suitable working potential. Furthermore, VO 2 (D)-based full cell with LiMn 2 O 4 as the cathode demonstrated high discharge capacity, good rate capability, and excellent cycling stability. The structural evolution, valence states of the VO 2 (D) electrode, and impedance variation of the full cell during cycling were investigated. The work reveals the potential of VO 2 (D) as a novel anode material for aqueous lithium-ion batteries.

Vanadium oxide has attracted extensive attention for electrochemical capacitors due to its wide range of versatility. However, due to the relative poor conductivity and chemical stability of vanadium oxide, severe losses of capacitance often occur during charge and discharge processes. Herein, a free-standing vanadium dioxide (VO 2 (B)) nanobelts/reduced graphene oxide (VO 2 /rGO) composite film was fabricated by assembly of VO 2 (B) nanobelts and rGO for supercapacitors. The flexible rGO sheets and VO 2 (B) nanobelts intertwined together to form a porous framework, which delivered a 353 F g −1 specific capacitance at 1 A g −1 , and after 500 cycles, the specific capacitance retention rate was 80% due to the enhanced conductivity of the VO 2 (B) nanobelts by rGO and increased transport of ions and electrons by the porous structures. An all-solid-state symmetrical supercapacitor was assembled from the VO 2 /rGO composites, which exhibited good energy storage performance with a maximum voltage of 1.6 V. The maximum power density is 7152 W kg −1 at the energy density of 3.13 W h kg −1 , ranking as one of the highest power densities for reported materials. In addition, after 10000 cycles, it still has a specific capacitance retention rate of 78% at 10 A g −1 .

Solar thermoelectric generation (STEG) is an excellent and environmentally-friendly way to convert thermal energy into electricity by utilizing Seebeck effect of thermoelectric material. However, how to overcome the rigidity and large output fluctuation of traditional STEG is the key to realize its large-scale application in self-powered devices. Herein, a smart light-driven flexible STEG system was designed and constructed through simple layered structure of VO 2 flexible film and carbon nanotube (CNT) thermoelectric modules. Based on the optical control characteristics of VO 2 flexible film due to the thermal crystal phase transformation, and the light capture, photo-thermal-electric conversion capabilities of CNT flexible film, the smart light-driven flexible STEG system exhibits good flexibility, light-thermal-electrical conversion and stable voltage output. In the above system, CNT, polyvinylidene fluoride (PVDF) as raw material and polyethyleneimine (PEI) as electron donor, p- and n-type flexible thermoelectric films and modules were constructed; VO 2 ultrafine powder was dispersed in polyvinylpyrrolidone (PVP), and the optical control VO 2 flexible film was obtained by simple spin coating on the flexible substrate. The system is so flexible that can be folded or bended to different shapes to adapt to different application environments. Furthermore, the intelligent light-driven flexible STEG system can obtain relatively stable voltage to prevent the damage of equipment caused by large voltage fluctuation and has great application potential in civil micro-self-powered devices.

Vanadium dioxide (VO 2 ) is a remarkable thermochromic material for application in adaptive infrared camouflage due to the reversible phase transition that is coupled with an abrupt change in infrared optical properties . However, the relatively high phase transition temperature and the unclear infrared optical modulation characteristics in the mid-infrared and far-infrared regions largely restrict its practical applications. Here, W-doped VO 2 nanoparticles were successfully prepared to reduce the transition temperature. When the effective doping amount of W was 1.70%, the transition temperature decreased to 43.2 °C. Importantly, the infrared properties of W-doped VO 2 nanoparticles were studied in both MWIR (3–5 μm) and LWIR (8–14 μm) thermal atmospheric windows, for the first time, which exhibited significant infrared optical changes, with emissivity variation of Δε = 0.17 and Δε = 0.28, respectively. These favorable results further promote the development of the adaptive camouflage.

Vanadium dioxide (VO 2 ) exhibits optical regulation properties in the solar band through a thermally induced insulator-to-metal phase transition near 68 ℃. Tungsten doping can decrease the VO 2 phase transition temperature ( Tc ) to near room temperature and enhance its applicability in smart windows for building energy saving. The optical regulation performance of tungsten-doped VO 2 (W-VO 2 ) is crucial for its smart window applications and varies with doping concentration. In this work, W-VO 2 nanoparticles were synthesized via a facile one-step hydrothermal method, and the effects of W doping on the Tc and particle morphology were systematically analyzed. This approach achieved a low Tc and improved optical performance without complex post-processing. The optical performance in the solar band was investigated with different doping concentrations ranging from 0.0 at to 2.0 at%. The sizes of the W-VO 2 nanoparticles ranged from 34.9 to 45.2 nm in diameter. The Tc decreased with increasing doping concentration and reached as low as 29.9 ℃ upon heating at a doping concentration of 2.0 at%. The W-VO 2 /PVP composite films exhibited excellent thermochromic performance. The luminous transmittance reached 52.71% and the solar modulation efficiency was up to 11.75% at a doping concentration of 1.0 at% and a volume fraction of 1.29%. These results demonstrate the potential of VO 2 nanoparticles in energy-saving smart window applications as a high-performance, low-cost material.

The use of electric-field to manipulate the transport properties of correlated oxides is promising for achieving nano-functional electronic devices. As a typical correlated oxide material, vanadium dioxide (VO 2 ) displays a special metal-insulator transition (MIT) at about 340 K. In this work, we select a water-free electrolyte gel, Li + /propylene carbonate, to achieve a non-volatile and reversible Li-doping and phase modulation in nano-VO 2 crystal film under gating voltages. Synchrotron characterizations indicate the originally insulating VO 2 undergoes an effective structure change and an increased V 3 d -O 2 p hybrid t 2 g -orbital occupancy, which is responsible for the metallic state formation as proved by first-principle calculation. The field-driving Li-doping shows pronounced facet dependence, indicating the existence of energetically favored channels for Li-ions diffusion along V-V chains as proved by dynamic stimulation. Our current findings will supply opportunities for the electric-field control of atomic sieve, correlated ionitronics and synaptic transistor.

Vanadium dioxide (VO2) is a key material for thermochromic smart windows that can respond to environmental temperature and modulate near-infrared irradiation by changing from a transparent state at low temperature to a more reflective state at high temperature, while maintaining visible transmittance. Here, we demonstrate for the first time that the Mott phase transition characteristics in VO2 nanoparticles can be remarkably modified by misfit strains occurring at the epitaxial interface between VO2 and the anatase TiO2 of VO2/TiO2 core–shell particles. The heteroepitaxial growth of the as-synthesized particles followed an unprecedented orientation relationship, and an epitaxial growth mechanism is proposed to explain this behavior. A relatively small theoretical coherent misfit (3–11%) and a moderate heating rate (20 °C·min–1) in the preparation of the core–shell structure were critically important from the thermodynamic and kinetic perspectives, respectively. The misfit-induced interfacial strain along the uniaxial cR axis increased the transition temperatures, especially on the cooling portion of the heating–cooling cycle, leading to a notably reduced transition hysteresis loop width (from 23.5 to 12.0 °C). Moreover, the optical band gap was also engineered by the interfacial effect. Such a reduced hysteresis showed a benefit for enhancing a rapid response for energy saving thermochromic smart windows.
