VSe₂ is a layered transition metal dichalcogenide (TMD) compound composed of vanadium and selenium, belonging to the family of two-dimensional materials with a hexagonal crystal structure. This is primarily a research material rather than a mature commercial product, investigated for its semiconducting to metallic properties and potential in energy storage, catalysis, and electronic applications. Engineers consider VSe₂ for emerging technologies in battery electrodes, hydrogen evolution catalysts, and flexible electronics because its layered structure enables mechanical exfoliation and integration into van der Waals heterostructures, offering advantages over graphene for applications requiring tunable electronic band gaps and catalytic activity.
