· JVASP-5491· V2Se9

V2Se9 is a vanadium selenide compound that belongs to the family of transition metal chalcogenides. This material is primarily of research and development interest rather than an established commercial product, with potential applications in electronic, photonic, and energy storage systems where layered or tunnel-structured metal chalcogenides show promise for tunable electronic properties and catalytic behavior.
