Facile synthesis of vacancy-induced 2H-MoS₂ nanosheets and defect investigation for supercapacitor application.

ABSTRACT: In this paper, a 2D molybdenum disulfide (MoS₂) nanosheet is prepared via a one-step hydrothermal method as electrode material for supercapacitors. Meanwhile, a series of MoS_2-x nanostructures with sulfur vacancies have been successfully obtained in an Ar/H₂ mixed atmosphere at different annealing temperatures. The prepared materials were characterized by XRD, HR-TEM, Raman and XPS to identify their morphology and crystal properties. MoS_2-x assembled by interconnected nanosheets (MoS_2-x -700) provides a maximum specific capacitance of 143.12 F g^-1 at a current density of 1.0 A g^-1 with 87.1% of initial capacitance reserved after 5000 cycles. The outstanding performance of the annealed M
