Application
Tungsten Dioxide Nanowires are designed for advanced applications due to their unique properties. While they exhibit a canary-yellow hue as a heavy powder and turn dark orange upon heating-returning to their original color upon cooling-they are insoluble in water but soluble in caustic alkalies and some acids with difficulty. These nanowires are noncombustible and are crucial in manufacturing tungstates, which are important for producing x-ray screens and fireproofing fabrics. Beyond these uses, they are integral in creating x-ray screen phosphors, fireproofing fabrics, and gas sensors, as well as serving as pigments in ceramics and paints. In innovative technological applications, Tungsten Dioxide Nanowires contribute to the development of electrochromic windows, smart windows, and semiconductors. Coupled with titanium dioxide, they could become efficient photocatalysts under visible light. Moreover, recent research highlights their potential as an anode material in high-performance lithium-ion batteries when used in a mesoporous nanocomposite form.
