Preparation of layered MoSe2 nanosheets on Ni-foam substrate with enhanced supercapacitor performance

Layered MoSe2 nanosheets were prepared on Ni-foam substrate with binder-free via a simple hydrothermal method. As the supercapacitor electrode material, the as-prepared materials showed high specific capacitance (1114.3 F g(-1)) and an extended long cycle life (maintain at least 104.7% after 1500 cycles) due to their specific structure, which showed significant potential for energy storage applications.
