Used as a precursor in sol-gel processes for preparing vanadium-containing oxide materials. It serves in the synthesis of catalysts for oxidation reactions, particularly in the production of maleic anhydride and sulfuric acid. Applied in coating technologies to produce electrochromic or conductive thin films due to vanadium oxide’s redox properties. Also utilized in the fabrication of sensors and energy storage materials, such as vanadium-based electrodes for batteries. Its reactivity with moisture allows controlled hydrolysis for nanostructured material development.
