· JVASP-27287· Nb2Se9

Nb₂Se₉ is a layered niobium selenide compound belonging to the transition metal chalcogenide family, characterized by a layered crystal structure similar to other metal dichalcogenides. This material is primarily of research interest rather than established industrial use, with potential applications in two-dimensional materials science, semiconductor devices, and catalysis, particularly where its layered structure and electronic properties could enable thin-film devices or electrochemical applications analogous to other TMD materials like MoS₂.
